Make sure that the processor does not make noise. Why is the computer system unit noisy and what to do? The main causes of computer noise
Probably every computer user, sooner or later, faced with the fact that the computer starts to make noise and work loudly. There are several ways to make your computer quieter. In this article, you will learn why your computer is noisy and how to make your computer quieter.
Why is the computer noisy
Main noise sources in computer:
- Fans (make noise when spinning fast)
- Hard drives (crack during operation)
- Drives (make a loud noise when they start reading/spinning the disc)
Main the reasons, because of which the computer starts to make noise:
- Overheat
- Thin body walls
- Loose computer components
- Wrong computer location
- Usage a large number small fans (less than 80mm)
- Wear and tear of computer components
Many of these causes are directly related to each other (for example, overheating and incorrect positioning of the computer) and in general result in a loud noise when the computer is running.
Now that we have determined why the computer is noisy, let's look at how to eliminate these causes and make a quiet computer.
Making the computer quieter
You can make a computer quieter both with the help of programs and actions with hardware components (the parts that make up a computer). In rare cases, it is possible to make the computer quieter without opening the system unit. Now we will look at the main ways and methods by which you can make your computer quieter.
Cleaning your computer from dust
The very first step to take if your computer starts to make noise is to clean it of dust. Dust clogs the fans and because of this, the temperature inside the case increases, and the fans start to work faster, because of this noise starts.
To clean the computer from dust, open the case, take a vacuum cleaner and, setting the vacuum cleaner to maximum power, collect dust from all fans (including those on the processor, video card and power supply) and motherboards. In no case do not touch the components of the system unit with a vacuum cleaner, you can damage them. Hold the vacuum cleaner tube in close proximity to computer components, but do not touch them.
In addition to a vacuum cleaner, you can use special cylinders with compressed air. You will simply blow off dust from computer components with them. Using air tanks is more efficient than vacuuming the system unit, but you have to pay for these tanks, although they are not so expensive.
Changing the fan speed
To reduce the noise emitted by computer fans, you can use the SpeedFan program. With it, you can change the fan speed, thereby reducing the noise of the computer. The program has a block of information that displays the temperature of various components of the computer.
And a block with the value of the fan speed, which you can change (pwm or speed).
So, we launch the SpeedFan program. Look at the temperatures. Now you need to run some resource-intensive program. It is best to run a resource-intensive game and play for 15 minutes to see and record the temperature values. If you are not a gamer, then you can run a movie in HD quality or some kind of test for computer performance. In general, you need to try to give the maximum load on the computer.
Record the temperatures under load and change the fan speed one by one. Start with 85%. Keep an eye on the temperature of the components not rising from changing the speed of the fans, and find the fan speed at which the computer runs quieter, but the temperature does not rise.
We reduced the speed, played, checked the temperature, if it hasn’t changed, then you can lower it again, etc.
Replacing thermal paste
Thermal paste is usually smeared with the junction of the processor with the cooler. Over time, it can lose its properties, which leads to overheating and increased fan noise. Replace the thermal paste and your computer will run quieter.
Chassis Fan Replacement
As a rule, fans are installed in any modern case. There must be at least two of them in order to remove heat well from the system unit. If the manufacturer has installed small or noisy fans, then the system unit will make extra noise. Replace small fans with larger ones with low noise (no more than 1200 rpm). It is best to use 120mm fans.
Body replacement
If you have a case with thin walls, then even if you have quiet fans installed, the noise will still be present. The case will not only let the noise from the fans through, but also vibrate from hard drive. It is better to replace such a case with a more expensive and durable one.
A good thick-walled case will let noise through if the case walls are not screwed in well enough. Check them and tighten the bolts.
Replace fan with heatsink
You can replace the fan on the processor with a heatsink. Thus, you provide passive cooling and reduce noise. But passive cooling is not suitable for powerful gaming computers. For very powerful computers, install water cooling.
Working with a hard drive
Many hard drives crackle and vibrate during operation. To reduce vibration, install rubber pads between the hard drive and the case. Typically, such gaskets are put on the screws that secure the hard drive to the case.
If the crackling in the hard drive appeared over time or became stronger, then this is one of the indicators that something is wrong with the hard drive. Check the status of the hard drive. If the hard drive is not in order, then it is better to replace it.
The hard drive can be replaced with an SSD drive that makes no noise at all.
Change the location of your computer
The computer should stand on level ground away from a heat source (battery, heater, etc.). Whatever the case vibrates, you can put rubber pads on the bottom of the case.
Do not place the system unit in closed cabinets and cabinets. So there will be no normal air circulation, and the computer will warm up.
Replace drive
If, when the drive is running (when you put in a disc), it starts to hum like a small factory, then the only way to solve this problem is to replace the drive with a quieter one.
If you are looking to purchase or build a new and quiet computer, please note the following:
- The body must be thick-walled
- Buy a larger case as these cases have better air circulation
- All fans must be large and low speed.
- Hard drives and drives must be attached to the case through rubber gaskets
- In the characteristics of the purchased components, pay attention to the level of noise emitted
Conclusion
Making a computer completely silent is extremely difficult, but you can make your computer quieter using the tips in this article.

What to do if the fan (cooler) is noisy? - you often have to deal with this issue. Before answering this question I propose to consider why the fan (cooler) is making noise. There are two reasons that contribute to the cause of fan (cooler) noise.
The first reason is the dust that has settled on the cooling radiator
The second reason is the wear of the fan itself
Fan noise due to settled dust on the laptop heatsink
Typically, a cooling fan is connected to a heatsink, which in turn is in contact with the object to be cooled, through a layer. In such cases, the dust deposited on the heatsink is the source of fan noise.
Noisy laptop fan. Why is the fan noisy?
Inside personal computer(system unit), many different fans are installed (we will look at how to find a fan that makes noise below), what can you say about a laptop whose cooling system is designed in such a way that one fan cools all devices at the same time (I have not seen a laptop , which has several cooling fans in the case).
The laptop's internal devices are cooled by a fan that fits snugly against devices that need cooling to run smoothly (such as the CPU, graphics chip).
Perhaps earlier, when your laptop was new, you did not notice how the cooling cooler works, but over time, the dust that has settled on the radiator cells cannot pass the air flow through it in full, and the fan has to “strain” to maintain temperature of devices, by increasing the speed of rotation thereof.
Over time, the fan noise can increase, and if you do not clean the laptop cooling system from dust in time, you will have to take it to a laptop repair service center. And believe me, the cost of repairing a laptop will cost many times more than a preventive one.
Solution. Fan noise in a laptop can be eliminated by cleaning the cooling system of dust and lubricating the cooling fan, and remember that blowing the cooling system is only a temporary way to eliminate the cause of overheating.
Noisy fan in the system unit. How to find a cooler that makes noise.
In the case of the system unit, it would seem simpler, it does not need to be disassembled as in the case of a laptop (apart from removing the side cover of the case), but there are many fans inside and it is more difficult to determine which fan makes noise. But do not despair, a cotton swab will help you if you are afraid to stop the rotating cooler with your finger.
To do this, you need to turn on the system unit with open lid, and stop the fans one by one in order to install the causative fan, which makes an increased sound during operation.
The cooling system of a computer is similar to the cooling system of a laptop in that the cooler is mounted on a heatsink, which, in turn, is attached to the cooling device through thermal paste. And the dust settled between the radiator and the cooler can also be a source of increased fan noise.
To eliminate noise, clean the radiator from dust and lubricate the cooler. For lubrication, use silicone grease or household machine oil, in no case use sunflower oil, it is not intended for this purpose.
If after cleaning the radiator and lubricating the fan, it is still noisy, then replacing the fan is inevitable.
Makes a lot of noise fan. Replacing a worn out fan
When fan noise is caused by wear on the fan bearing, replacement of the fan is inevitable. A worn out fan is characterized by a strong noise, which is accompanied by wear of the bearing, a radial beating of the impeller against the elements of the cooler housing appears. There is no need to wait until your fan stops, such a fan should be replaced.
A guide to reducing the noise level from the operation of a laptop, netbook, computer and other similar devices. The manual also describes how you can extend their service life.
General information about noise, what makes it and why you need to reduce it
The vast majority of modern technology makes a variety of noises during operation. They are very different: clicks, thin squeak, rumble and so on. Let us first understand where they come from, what publishes them.
The biggest source of noise is the cooling fan. The faster it rotates, the stronger and higher in tone the rumble from its work. If the bearing of the fan is worn out, then the hum becomes much stronger due to the imbalance of the impeller with the blades. The accumulation of dust on the blades also increases the noise level and also accelerates the wear of the bearings.
The second source of noise is the optical disc drive and hard drive. The optical disc drive emits a fairly loud hum. The higher the speed of rotation of the disk and the less balanced it is, the stronger the rumble. Winchester also emits a hum, but it is much quieter. Also, the hard drive makes clicks from time to time. This is due to the fact that there is a block of magnetic heads inside the hard drive. He moves very quickly, in jerks. This is how clicks are made.
So we went through the main sources of noise. Now let's figure out why it needs to be reduced.
The most obvious reason is that the noise is annoying and interferes with work. Few people like to work with a device that buzzes like a vacuum cleaner. In addition, many leave laptops and computers overnight for downloading. Excessive noise interferes with sleep.
A less obvious reason is the increased wear of the elements. It is quite logical that if the fan rotates faster, then the bearing that holds the impeller with blades will wear out faster. Not everyone will like the prospect of changing the fan every 1-3 years. With the winchester a similar story.
Why reduce the noise figured out. It remains to find out how it can be reduced. This will be discussed in this guide. First, let's look at how to reduce fan noise, and then how to make hard drive clicks quieter.
Fan Noise Reduction
Important notes on disassembling a laptop:
- Before disassembling the device, it is mandatory to disconnect the battery and power supply;
- When disassembling, it is highly desirable to use an antistatic wrist strap and mat;
- In addition to bolts, the plastic parts of laptops are often held in place by latches. You need to be careful with them;
- In many laptops, accessing the fan involves separating the halves of the laptop base. They are usually held together by bolts on the bottom of the laptop. On some models, they are held in place by bolts under the keyboard. To remove the keyboard, you often need to slide the latches at the top into the case. How to do this is shown in the material: How to remove the keyboard. Notebooks Acer Aspire ;
- Bolts in laptops are different. They may vary in both length and diameter. When disassembling, somehow remember or write down which bolt you unscrewed from where.
These are the main nuances. Don't worry, it's really not that hard.
Our goal is to get to the fan. Loosen the bolts:
and remove it:
Next, you need to remove the impeller itself with the blades. In some cases, it can simply be removed, and in some cases, to remove it, you must first remove the lock washer on the other side of the fan. Often this washer is located under the plug. Consider this whole process using the example of a conventional computer fan. In laptops, the fan has a completely similar design. First, remove the sticker above the plug, and then the plug itself:
Handle stickers with care. We still have to stick it back.
That's how we got to the retaining ring. It enters the groove on the shaft and has a small notch along the radius. We pry with something sharp and carefully remove:
Here we have removed the impeller:
Now you need to carefully clean it with a napkin or dust cloth:
After that, you need to remove the old grease from the impeller shaft and from the fan bearings. For better removal it is recommended to use alcohol or other solvents. If you decide to use acetone, then you should take into account that not all plastics tolerate it normally.
After removing the old grease, you can proceed to applying a new one. In our case, it is best to use bearing greases. When choosing a lubricant, it is worth considering the number of revolutions per minute. For our purposes, lubricants are suitable that are designed for a speed of up to 5-10 thousand revolutions per minute. Some lubricants have protective and restorative properties that can compensate for slight wear on fan bearings. You can easily find them in auto parts stores.
If you do not find the above lubricants, then you can use silicone, synthetic, mineral, machine oils. Since most fans do not contain proper oil seals to keep the oil in the bearing, it is not recommended to use too thin oil.
AT this example I used protective lubricant "Hado". Lubricate the bearing and fan shaft:
At the same time, you can clean the laptop heatsink from dust and other debris. In a not particularly neglected case, it may look like this:
Naturally, in order to somehow pump air through this lump of garbage, the fan must rotate faster and make more noise. The wear of the fan bearing is also much higher in this case. After cleaning, the radiator looks something like this:
Now you can put everything back together. If after a while the fan starts to hum again, this indicates a strong wear of the fan bearings. It is necessary to replace either the bearing itself, or buy a new fan. You can find it by the model number (located on the back of the fan) on various online auction sites. You can also contact the service center.
Consider now how to reduce the noise level of the hard drive.
Decreasing the volume of hard drive clicks
Another source of noise is the hard drive. As mentioned above, clicks during the rapid movement of the block with magnetic heads. Therefore, to make clicks quieter, you need to reduce the speed of movement of the hard drive heads. Reducing the speed of head movement will have a positive effect on the life of the hard disk. However, there are also disadvantages: with a decrease in the speed of movement of the heads, the search time slightly increases. For most tasks, this will not be noticeable.
Now let's figure out how you can reduce the speed of movement of the block of heads. Fortunately, everything has already been thought of for us. Hard drive manufacturers have invented such a function as: AAM. By changing the parameter value AAM, you can increase or decrease the speed of movement of the heads.
There are several utilities available to change this setting. The simplest and most convenient of them is quietHDD(/). Download, unpack and run this utility:
At the first start, the utility checks whether the value can be changed. AAM and APM. We right-click on the utility icon near the clock. In the menu choose Settings:
In the settings, go to the tab AAM Settings and move the sliders to the left. The top is in charge and the bottom sliders let you control AAM when the laptop is plugged in or running on batteries.
You can also go to the tab Manual Settings for testing, move the slider AAM to the left and press the button Set AAM Value:
On the tab misc. Settings check if there is a checkmark next to Enable AAM Control:
Click on apply
Check if the utility works. Right-click on its icon and look at the top line with AAM:
The AAM value actually went down to 128, the hard drive began to work a little quieter.
There is one more little touch left. To make the hard drive work less noisily (with a lower value AAM) is required for this utility to run in the background. You need to add it to the startup list so as not to turn it on every time you turn on the laptop.
To do this, first create an application shortcut on Desktop, and then transfer it to a folder in the menu Start:
That's all. Thank you for your attention.

A detailed description of how to solve hardware problems with turning on a laptop, with image defects, as well as many other problems at home.
Are you having a problem with your laptop? You don't know what to do? Then this material is for you. The solution to the problem should start from here. Here are the solutions typical problems with a laptop.
When extraneous and sometimes loud sounds are observed in the computer, you should give this importance in a timely manner, probably noisy cooler, the hard drive cracks or the BIOS gives certain signals about a hardware failure. When noises are observed in the cooler, the situation is almost always correctable and can be eliminated without serious financial outlays.
Why is the cooler noisy?
The cooler is a plastic fan that is installed on the radiator of heating elements, in particular, these are microprocessors. Thanks to its work, it is possible to efficiently remove heat and the processor can work normally, which cannot be achieved with certain malfunctions in the cooler. When the cooler makes a lot of noise, you must first determine the cause, and then proceed to solve the problem.
So there are several reasons for noise:
- Pollution. The most common problem, its characteristic symptom, is noise that was caused without any intervention in the computer. At the same time, the user has no idea why the noise is observed, since before everything was in order. With the accumulation of a large amount of dust and dirt on the cooler, it gradually loses its quality characteristics and starts making noise, clinging to the edges of the case. The problem is fraught with the fact that the blades will be damaged: broken, unevenly worn, which will lead to an unbalance of the device. In another case, constant mechanical action prevents the cooler from moving normally, and it stops, which leads to overheating and failure of the power supply, processor, video card;
- Lubricant. The cooler, like all moving parts, is lubricated, it uses a silicone type. Periodically, the oil should be added, otherwise sooner or later it will dry out. Another case is when a person adds lubricant to the fan too often and this causes it to become clogged. In some cases, WD-40 is used, which is categorically not suitable for this purpose (although many claim that it works, you will have to lubricate it every 1-4 weeks), you should buy special silicone oil;
- High speed cooler. In a normal situation, the computer independently determines at what speed the fan will spin. Some experts set parameters when the number of revolutions is always maximum, respectively, and noise occurs, as well as unproductive energy consumption. The user will simply have to reduce the number of revolutions or turn on automatic adjustment;
- Incorrect body mounting. Typically, coolers are installed on the case of a system unit or laptop, as well as on a processor heatsink. If the fasteners are loose, rattling will become noticeable, and, accordingly, certain problems with the performance of the fan and the quality of heat dissipation;
- A large number of coolers. New computers are increasingly equipped with coolers due to high performance and strong heat. If you have a case with 5 or more active cooling systems, then count on low level there is no noise, although it is worth checking, maybe the situation can be improved somewhat.
It is worth noting that the noise increases with a heavy load on the PC, for example, running games, demanding applications, and this is a normal behavior of the computer.
Decontamination and lubrication
So, what to do when the cooler makes noise? The problem is that we do not know if the cooler is noisy on the processor, in the power supply, video adapter, etc. Before proceeding with the cleaning procedure, it is necessary to determine which cooler is making the unpleasant noise.
In the case of a laptop, everything is somewhat simpler, it does not provide a large number of fans, so the noise almost always comes from a visible device that is located behind bars, usually from below or on the sides of the PC. But the laptop is harder to clean.
For a desktop computer, everything is somewhat more complicated, almost always it has at least 3 active cooling systems. To determine the culprit of an unwanted sound, it is enough to stop each cooler in turn with the touch of a hand and check for noise. First of all, you should start by stopping the fan on the central processor, then the video adapter, and, ultimately, on the power supply.
So, in order to eliminate noise, you should clean and lubricate the devices, consider the example of a stationary PC:
- Turn off the computer and disconnect the power from the system unit;
- Remove the side cover, usually the one on the left;
- There are several options here:
- If the noise is from the central processor, it is necessary to unscrew 4 bolts along the edges of the case with the fan and remove it, but first disconnect the cable from the motherboard (you may not disconnect it). On one side there is a sticker that needs to be carefully peeled off. In order not to bother, you can simply pour a few drops of silicone oil into the hole. It is necessary to clean the blades with a brush or brush, also remove contamination from the housing itself and the radiator;
- When noise comes from the video card, you need to clean it up. It should be noted right away that coolers are rarely clogged, since they are most often located at the bottom of the board, although not always. First of all, disconnect the video adapter by unscrewing the bolt that secures one of the sides to the frame. You may have to remove the protective cover from the device. Often the cooler mount is located under it, you will have to take a small screwdriver and insert it between the blades, unscrewing the bolts. Remove the connection cable and peel off the sticker. Clean off dirt and drip oil;
- Noise coming from the power supply is the most common cause of deviations. The main difficulty is that it is necessary to disassemble the block body. First of all, unscrew the 4 bolts holding the power supply together with the case (do not confuse with the cooler mounts). Then carefully remove it and unscrew 4 more bolts connecting the 2 parts together. Now unscrew the fan itself. Clean it with a brush and grease.
- Carefully clean the system unit from dirt in other places, otherwise the cooler will soon clog again;
- Now assemble and connect everything back;
- You can start your computer and enjoy quiet operation.
There is such a nuance here that a lot of used oil can accumulate inside the cooler itself, which has thickened and blocks its free movement. Then you will have to completely disassemble and clean the fan by prying a small latch in the hole under the sticker.
On a laptop, things are ambiguous, as each model has distinctive parsing methods. In order to get to the cooler, it is better to look at the corresponding disassembly instructions, and cleaning and lubricating occurs in the same way as on a PC.
How to reduce the speed in the cooler?
If the cooler is noisy in a laptop or desktop computer, then a simple reduction in speed may come in handy.
The easiest way is to go into the BIOS and set the Q-Fan Mode value to the standard. You can also use reobas, programs, for example, SpeedFan. The use of reobas is rarely justified, since you have to reach for it all the time, but you can adjust the speed at any time. The application makes settings directly from Windows.
Take care of your computer, and it will work for a long time and with high quality!
If you still have questions on the topic “Why is the cooler making noise and what to do in this case?”, You can ask them in the comments

Most computers are equipped with an air cooling system. This means that its parts are cooled by air currents that are created using fans. Sometimes trouble happens, and there is an alarming noise. In this article, I will tell you about why the cooler makes a lot of noise in a desktop computer and laptop, and how you can get rid of it.
Often you can find advice that if the cooler is very noisy, you need to reduce its rotation speed using special programs or through the BIOS. However, I would not recommend this to non-experienced users. Reducing the speed may cause overheating of parts with their further lethal outcome and expensive repairs.
Reason 1. Dust in the cooling system
If the cooler is making a lot of noise, then open your computer and take a look at the dust that has accumulated there. It is she who most often causes noise. So, the dust that has settled on the fan blades changes its centrifugal, from which it begins to buzz. Also, if dust interferes with the cooling airflow, the cooler has to spin faster to keep the parts cool.
Dust from a desktop computer or laptop can be removed with a small vacuum cleaner, hair dryer or brush. You can also use a cotton swab dipped in alcohol to remove old, hardened pieces of dust.
Be careful when cleaning dust. The computer must be powered off at this point. You can not make rough movements, so as not to damage anything inside. When using alcohol, do not allow it to get on the boards. After treatment with alcohol, the computer can only be turned on after 10-15 minutes.
Reason 2. Unlubricated cooler
If the cooler makes a lot of noise, the reason may be in the fan itself. If cleaning the dust did not help, then the bearing should be lubricated with oil. You can use machine oil for this.
To lubricate the cooler, you can not use automobile or vegetable oil, and even more so vaseline.
In order to lubricate the cooler, you can use a syringe with a needle or cotton wool. In most cases, you can not even remove the fan itself, but simply tear off the decorative sticker in the center - from here you can access the bearing.
Reason 3. Broken bearing
If the fan bearing is worn out, it will make noise. As a rule, the accompanying symptoms are the non-centered position of the cooler, and blades touching its body during rotation.
In this case, if the cooler makes a lot of noise, that's still good. In the worst case, it will stop and everything will overheat. Therefore, it is better not to wait for this and just change the fan.
Cracks in the fan blades can also be attributed to the category of the same reason. If they are found, you will also have to change the fan. True, this rarely happens.
Reason 4. Poorly fixed parts
It is possible that it is not the cooler that makes noise in your computer, but something else that gives in to vibrations from the rotation of the cooler. For example, if HDD or the disk drive is poorly fixed in the system unit, then they will vibrate and give an unpleasant noise. A similar situation may occur if the screws in the case or parts of the laptop are poorly tightened.
What is there to say. It happens that a cactus in a pot, placed on the case of the system unit, begins to vibrate so much that it interferes with work.
What noise is normal and what is abnormal
If the cooler makes a lot of noise, then first understand how much.
- The fan noise should be similar to the sound of a small draft. A little noise is normal.
- If during games or when running some heavy programs, the cooler makes a lot of noise, then this is normal, since the processor is under more stress and the fan starts spinning faster to cool it (although it will not hurt to clean the dust if it has not been done for a long time) .
And remember that the system unit makes more noise than any laptop. So, if your friend with a laptop has almost no noise, then do not rush to look for problems in your system unit - it should make more noise.
How to find out which cooler is noisy
With a laptop, everything is simple - in the vast majority of cases there is only one fan. But with a stationary computer it is more difficult - at least two fans: on the processor and in the power supply. And maybe more.
If the cooler in the system unit makes a lot of noise, then in most cases it helps to simply open the case, listen and understand the direction of the excess sound in order to find out the source. If this does not help, you can try a risky method - gently and briefly (for a moment) stop (slow down rotation) each of the fans by pressing on their center with your finger. However, this can be dangerous for iron, so try to just listen.
When a faulty cooler is found, proceed to treatment.
In this article, we will talk about what to do if the laptop heats up, makes noise, and periodically turns off.
AT last years ordinary users are increasingly abandoning the use of desktop computers, making a choice in favor of laptops. This is due to the fact that the laptop is more compact and mobile, and its performance does not lag behind a standard PC.
In turn, such a device has a specific structure, which is characterized by a number of disadvantages. First of all, this is a strong heating of the case during operation, accompanied by intense noise. There are many reasons why such problems occur, and they must be eliminated as soon as possible. More detailed information about this is provided below.
What should I do if my laptop is overheating?
The presence of various kinds of distortions on the display of a working laptop, excessive heating of the lower part of its case, as well as extraneous noises are an alarming sign and indicate the presence of an internal malfunction. Such problems must be fixed as soon as possible, otherwise the processor, graphics adapter and other parts are likely to overheat, which can lead to their complete inoperability.
A laptop can overheat for two reasons:
- Your laptop is clogged with a layer of dust, which also leads to a lot of noise and heat throughout the laptop system.
- There is no thermal paste on the central processor, or it has simply dried up and dried out.
But still, we note that both cases involve disassembling the device.
Dry or missing thermal paste on CPU and adapters
thermal paste located on the coolers of the video card and the central processor. It must be replaced with a new paste using a plastic card. If you have not previously performed such actions, it is better to ask for help from specialists, since the replacement procedure is specific.
The outer part of the fan is clogged with a layer of dust
The formation of dust, as a rule, is associated with the active operation of coolers. Very often, it accumulates on the cooling grates and makes it difficult for air to pass through. Therefore, dust should be removed regularly.
The hard drive has failed
Continuous operation of the laptop in some cases leads to the appearance of clicks that are not characteristic of its operation. These are symptoms of a hard drive failure or malfunction of the cooling radiators.
In most cases, the failure of a hard drive requires its replacement, since the resource of such devices is limited. Shocks and mechanical damage also negatively affect the condition of the disks and sometimes even lead to their complete inoperability.
Fans (coolers) clogged with dust and debris
If the source of outside noise is the cooler, it is necessary to check whether debris or foreign objects have got inside the case, and whether the grease on the bearings has dried up. Accordingly, it is necessary to lubricate the bearings with a specially designed composition and carefully clean the housing.
What should be done if extraneous noise is detected on a laptop?
- If the slightest signs of a malfunction of the device appear, promptly eliminate their cause.
- If it is not possible to clean the device yourself, contact the service center for help.
- Monitor the status of the CPU, video card and hard drives. Ensure their repair in time in cases of frequent heating and other malfunctions.
Well, on this we perhaps finish our article today.
It doesn't matter what model your fridge is, what matters is how it works. If the refrigerator makes noise, it is always unpleasant and raises concerns about its condition. But, even if the refrigerator is very buzzing or making noise, this does not mean at all that it is broken. Consider the causes of noise, the most common in practice, and ways to eliminate them.
Incorrect installation of the refrigerator
The situation is simple and common - you bought a new refrigerator, put it in the kitchen, but the noise from it is like from the old one. What's the matter? The reason is simple: you might not have checked the horizontal and vertical position of the refrigerator body. Due to skew, the compressor may make noise when the housing comes into contact with the pipeline or metal parts of other components. Or it may be that one of the adjustable legs of the refrigerator simply hangs in the air due to skew, and due to insufficient support, the unit body vibrates and makes unpleasant noises.
Elimination: How to reduce noise in this case? The position of the refrigerator is set using a conventional spirit level (building level). If it is not there, use a plumb line, which can be made from any thread and a weight of 20-50 grams. But even with a strictly vertical / horizontal position of the body, check the touch points of the legs to the floor. Perhaps the floor is uneven, and the leg that hangs in the air will have to be adjusted - for this, the legs are threaded.
The rather loud noise of the refrigerator due to the fact that the compressor is operating in limited capacity mode is the second most frequently eliminated cause. This is especially true for small-sized or furnished apartments.
If you have moved the refrigerator too close to the wall; if the refrigerator is furnished with close furniture; if the back of the cabinet (radiator) touches or is too close to a wall, the airflow to the condenser is difficult. Therefore, it is not cooled enough, creating an additional load on the compressor, which, in turn, starts to make noise from overloads - valves knock, the engine vibrates, transmitting vibrations to other components. In addition, a layer of ice gradually accumulates on the condenser, which can also touch other parts of the structure and make noise.
Elimination: In such a situation, you can reduce the noise of the refrigerator in understandable ways - move the unit away from the wall at least 20 cm, remove furniture or other objects that are too close, and also clean the back wall of the refrigerator. Remove the layer of dust, remove dirt from the compressor, condenser, radiator and piping, defrost the refrigerator so that the frost on the condenser (if any) can be removed. It is advisable to carry out preventive maintenance of the refrigerator at least once a month. All this can be done on your own, without resorting to the help of a professional refrigerator.
Compressor housing loose or loose
But what if the refrigerator makes noises or extraneous sounds all the time, but all of the above methods do not help? Check if the compressor is well fixed in its seat.
Elimination: In older models, the compressor is suspended on springs - their weakening or displacement to the side can cause noise from the contact of the engine housing with the metal of other parts. The pipeline from the refrigerator to the radiator is a good sound resonator. The refrigerator buzzes very strongly if the rubber gaskets under the compressor housing are worn out - they are crumpled or broken. Springs or gaskets need to be replaced.
It often happens the other way around - the refrigerator makes a lot of noise if, after installation, you did not remove the transport bolts of the compressor (the arrow points to them in the picture). These are long bolts Ø 12-16 mm, and they fix the compressor during transportation so that it does not break the pipeline and damage the casing itself. Here, too, everything is simple - remove the bolts, check the gaskets or springs for integrity.
Refrigerator fan defective
If the noise of the unit is very loud, check the operation of the refrigerator fans. This applies only to models with the "No Frost" system - they can even have two fans installed. One is for cooling the evaporator of the refrigerator compartment, the second is for cooling the evaporator of the freezer.
Your refrigerator is noisy - what to do to find the cause? With constant temperature fluctuations, the grease in the motor bearings dries out, and the refrigerator hums strongly from fan vibrations. Also, frost on the evaporator, which can form as a result of poor operation of the heating element or its breakdown, grows over time, and the fan blades begin to cling to it, and the refrigerator hums strongly.
Elimination: First, get rid of the ice crust on the evaporator - you can do it yourself. Then check the presence of grease in the fan bearings, add it. Bearings will most likely be bronze or brass, so lubrication is very necessary for them.
Malfunction of electrical circuits
The next reason why your refrigerator began to make extraneous noises is a malfunction of the electrical part.
- If the start-up relay fails, the refrigerator behaves aggressively - when it is turned on, it buzzes a lot, growls, and after a few seconds it turns off abruptly.
elimination: relay replacement - for this you will have to use the services of a professional if you cannot handle it yourself.
- The fan motor windings burned out - another reason why the refrigerator began to make a lot of noise when turned on.
elimination: check the windings with a tester for short circuit or resistance leakage to the motor housing. In both the first and second cases, the engine will have to be changed. Although there are cases when, in case of leakage to the case, it is enough to dry the engine thoroughly, and infinite resistance will be restored.
- Another reason why the refrigerator makes noise is the compressor motor burned out. You can check this by touching the case. You can hold your hand on a working compressor - it is not too hot, but just warm. If the case is overheated, then you need to check the engine.
Eliminate the cause of the noise: Same as with fan. But it will not be possible to dry the engine - it is pressed into the compressor, therefore - only a replacement.
- The evaporator heater burned out - this is the next reason why the refrigerator is noisy. Ice on the surface of the evaporator interferes with the normal operation of the compressor - in high load mode, the noise from the engine will be strong.
Moreover, the sound can be transmitted through the pipeline to the radiator, which will only enhance the sound effect. Also, with a thick layer of ice on the evaporator, the refrigerant is supplied to the compressor in a semi-liquid state, and this operation is called the “wet run” of the compressor. Working to the limit can cause water hammer and stop the compressor completely.
This is why the refrigerator buzzes - the position of the valves and the piston is violated, but the crankshaft continues to rotate, causing the refrigerator to make grinding and clanging sounds.
Troubleshooting: Check the heating element for serviceability - this can be done by checking the continuity of the circuit with a tester for an open circuit. If the heating element burned out, you can replace it yourself.
Clogged pipeline
What to do if the refrigerator continues to make noise and what else could be the problem? The throttle and the filter of the unit are usually clogged. This is expressed in a decrease in the production of cold and an increase in the load on the compressor, so the refrigerator makes noise and knocks along with the compressor.
elimination: Only call the refrigerator, as it is necessary to remove the blockage special equipment.
Refrigerant overdose
Why is the refrigerator knocking? When charging the unit's piping with refrigerant (this may be necessary), the refrigeration unit may mistakenly add an excess amount of freon. This will result in a noticeable reduction in refrigeration capacity, but this problem can be easily solved by bleeding off the refrigerant.
In such cases, you just need to watch how the refrigerator works for 2-3 hours and ask the master (if necessary) to bleed the refrigerant.
Video instruction
A short video tutorial on how to quickly and cheaply eliminate one of the causes of noise that a refrigerator can make. In the example, the cause of the noise was the mechanical contact of the pipeline with the body and radiator of the refrigerator. Due to the large area of the vibrating radiator, the noise was clearly audible, especially at night.
If you buy a branded model when choosing a refrigerator, you will be satisfied that the compressor works silently and the refrigerator does not knock. Even when all functions are turned on at once in new refrigerators, the noise level will be significantly lower, and the unit will work more reliably and longer than cheap models.
In contact with
Computer noise is tiring and makes it difficult to concentrate. Even if you are used to monotonous noise, it will probably bother other members of your family. Making a computer silent is almost impossible, but we will talk about how to reduce fan noise, reduce vibration and nullify extraneous sounds in the system unit.
Foreword
Before we talk about the causes of noise, we will give two tips regarding the placement and care of the PC:
1. Do not keep your computer in a hot place. For example, near a battery, heater, or under direct sunlight. In a stuffy room, the cooling system will be forced to operate at maximum speed, which will generate noise.
2. Regularly clean the system unit from dust. And most importantly, which is rarely talked about, keep the room clean. Then you will have to do less cleaning.
We list the possible sources of noise in descending order: from the most noticeable to the least significant.
CPU cooler
As a rule, this is the main violator of silence. If the CPU fan is buzzing, don't try to fix it. After an unsuccessful repair, it may stop altogether. In this case, the processor will overheat and may fail.
In many system units, processor coolers are buzzing not because they are out of order, but because of poor quality. These are noisy from the moment of purchase and, as a rule, do not cool well.
When choosing a CPU cooler, it's definitely not worth saving. You should purchase a fan from serious manufacturers. We recommend Zalman. Buying a quality cooler good heatsink, you will spend more money, but you will get reliability and silence in return.
From our experience, we can say that after replacing cheap coolers with heat sinks with high-quality ones, the idle temperature of the processor often dropped from 60-65 to 30-35 degrees Celsius.
Video card cooler
Replacing a cooler on a video adapter can be problematic if it is branded (non-standard). Here you have to select the most suitable size and screw it into the old radiator. On sale there are universal coolers with a set of fasteners of different sizes.
If you installed a cooler on a video card where it was not there before (silencer) and connected it to the power connector on the motherboard, then you can lower its speed using a resistor or replace the 12V wire with 5V.

Power Supply
Despite the fact that almost all models use 120-mm fans (which are considered quieter than 80 mm), power supplies also vary widely in terms of noise factor. One of the quietest and highest quality products are Chieftec, Thermaltake, AeroCool. But before buying a PSU, we advise you to carefully study it. specifications and specify the declared noise level in decibels.
Additional cooling of the body - blowing or blowing
In cheap cases, the blower fan can be the loudest of all. And the most annoying thing is that it often makes more annoying sounds than good. If the air circulation in a low-quality Chinese case happens “haphazardly”, then additional coolers will not really improve the situation. We advise you to turn off the additional cooling of the case, compare the temperature difference between the nodes before and after, and decide whether this is exactly what your system needs.
Rattle and vibration
Both the case itself and the radiators can rattle. Cheap cases have thin, curved walls and often don't fit snugly. The best thing to do, of course, is to buy a high-quality case. But if you do not want to spend money, you can try to solve the problem by finalizing the "box". Inspect the system unit and try to find out the source of the rattling. If the side cover on the back of the motherboard is rattling, glue a foam or rubber pad to it.
It also happens that the whole body vibrates. The cause is often an unbalanced CPU fan. Such a comrade should be replaced without options.
motherboard chipset cooling
Universal fan Titan for installation on a chipset or video card
The chipset fan usually doesn't make a lot of noise, except when it has failed. Here - the same moral: if the cooler has exhausted its resource, then it is better to replace it. Lubrication will not bring long-term results. You will only waste precious time, but in a few weeks you will again hear this terrible roar and crackle.
HDD
The noise of the hard drive is not very loud, but it can be no less annoying. The best solution to this problem is to install an SSD. There are no mechanics in it and therefore it works silently. As a bonus, you will get a measurable improvement in system response. So at this point, the solution is extremely simple. There would be money to buy a solid state drive.
If this option does not suit you, install rubber spacers between the mounting bolts and the chassis basket. We note right away that usually they are not able to remove the resonance completely.
You can also unscrew the hard drive from the basket and put it on a soft base. It is important here that its material and shape allow air to circulate under the drive. In general, this is a specific budget option. But this way you can eliminate the resonance problem from the HDD mechanics throughout the case.
DVD+-RW / Bluray
Let's mention the optical disc drive purely symbolically. First, they are already quite rarely used. And secondly, if the drive is working, then not all the time. So it's probably not that much of a problem. Here you can advise to use flash drives. It will be quieter and faster.
We hope these tips will help you reduce fan noise and eliminate extraneous sounds in your PC.
Each refrigerator buzzes during operation - the average noise level is 38-44 dB. If it makes more noise, uncomfortable conditions are created both in the kitchen and in other rooms. Sometimes the problem can be solved, but it happens that a lot of noise is simply a consequence of the operation of the compressor and other elements of the equipment. It is possible to determine the method and possibility of eliminating sounds that interfere with the owner of the refrigerator by finding out the cause of their appearance. Let's figure out why the equipment works loudly: it buzzes, makes noise, clicks, whistles and what to do about it.
What noise can not be called a problem
Not in every apartment or house you can find a modern refrigeration equipment, creating noise within acceptable levels - up to 40 dB. Sometimes owners of old but reliable models continue to use them, not paying attention to the buzzing compressor. In this case, the noise from the old Atlant or the even more outdated Biryus freezer is unlikely to be reduced to an acceptable level. For such technology, it is the norm.
You should react differently if noise is emitted by more modern models of well-known manufacturers - for example, Bosch or Samsung. If it becomes noisy only after starting the device that is disconnected from the power supply, this is also normal. But, when a new refrigerator continues to work loudly intermittently or constantly, it is worth looking for a problem, focusing on the nature of the noise and the situations in which it usually appears.
Sound character
To determine the causes of noise, you can focus on their nature. Listening to the buzz of technology, you can distinguish the following types of sounds:
- A hum or howl, reminiscent of the sound of a blizzard. Refrigerators begin to howl due to the operation of the compressor. The noise is complemented by the vibration of the case and other parts. When using two-compressor refrigerators such as Liebherr SBS 7252, the hum lasts longer.
- Strange sound like gurgling or gurgling. Sometimes the equipment begins to hiss, hum or grunt - most often the sound is heard when the compressor is turned on. This is because the new refrigerants are noisier than the older R12 and R134a brands.
- Whistling. Refrigerators can whistle when ice is touched by the fan blades - a problem that occurs if you do not defrost models for a long time without the No Frost mode.
- Buzz. The cause of the sound is a burnt out evaporator heater in the freezer. Due to the formation of a large amount of ice, the motor begins to constantly buzz and rattle loudly.
- Clicks. The reason is the operation of temperature relays. Usually they are ignored. But, if the refrigerator clicks harder, the technique may signal a problem, to eliminate which the relay is changed. The problem is often found with Ariston Hotpoint brand products.
- monotonous broadband noise. The fan is most likely the cause.
- A sound like ringing and rattling. The refrigerator may rattle or ring when not in the correct position.
Important! Some refrigerators may crack when placed too close to walls or radiators. The problem is solved for any refrigerator by moving a sufficient distance from them. And owners of such inexpensive models as Stinol may encounter a slight crack due to the expansion and contraction of the plastic walls of the refrigerator.
Situations in which extraneous sounds appear
Noise when turning on the refrigerator is not considered a serious problem - it is usually caused by the starting current required to start the compressor rotor. But, if an extraneous rattling sound also occurs when turning off, there is a possibility that the refrigerant pipes touch the casing or frame. You can reduce or completely eliminate the noise by detecting the touch and manually fixing the problem.
The refrigerator can make noise and buzz without ceasing due to compressor wear - the formation of backlash, abrasion of pistons or piston rings. Not a single model is immune from such a buzz, including products from the popular Indesit brand. If the parts are badly worn, engine decompression appears. At the same time, in addition to extraneous sounds, an increase in the operating time of the motor is noted. The problem should be fixed by repairing or replacing the engine.
Other key situations include:
- The equipment makes a lot of noise not only at the beginning of work, but also when it is turned off - the cause may be weakened compressor shock absorbers. Because of this, the vibration of the motor becomes more noticeable, and the noise is stronger when it stops. Noise should be reduced by adjusting the dampers.
- If the noise appeared at the new refrigerator, the reason may turn out to be the most prosaic - the transport bolts have not been removed from the compressor.
- The equipment begins to shake and buzz after moving or installing in a new place - it is worth checking its position on the floor. The equipment may need to be adjusted.
- Extraneous sounds are heard after closing the door - a lot of food was loaded into the refrigerator, so the motor starts to lower the temperature to the set level. The same reason for the sounds that appear after defrosting any model - from Bosch to Saratov.
- The noise that appeared after loading freon may be evidence of an excessive charge of refrigerant.
Owners of Indesit refrigerators and other popular brands may also encounter such a problem as extraneous sounds when filling the ice generator. This happens due to mineral deposits accumulated inside the valve. There is only one thing you can do here - replace the clogged part.
Refrigerator type
There are also noises that are typical for the breakdown of refrigerators of a certain type. A strange creak and rattle can be observed in many modern models with the No Frost system, which are often found among LG brand products. Such noises indicate a malfunction of the fan. They solve the problem by defrosting the equipment and calling the master.
Owners of built-in refrigerators Ariston Hotpoint and other brands are faced with loud noise immediately after installation. This happens due to the fact that the equipment becomes too close to other surfaces - walls and shelves. Even effective soundproofing does not always help to get rid of noise.
conclusions
Having figured out what causes different options for refrigerator noise, you should choose a method to fix the problem. If it didn’t work out why the equipment is buzzing, buzzing or cracking, it should be entrusted to the service specialists to diagnose and fix the problem.
