What to do if the laptop vibrates. Why is my laptop cracking? How to eliminate cooler and hard drive noise

Reasons

If you notice that the fan in your laptop is humming, you should first understand the factors that provoke the cause of this phenomenon:

incorrectly selected settings that are responsible for the fan rotation speed;
some parts of the device become very hot;
the cooler impeller bearings are worn out;
A large accumulation of dust or dirt has formed on the cooler blades.

The fan in the laptop is humming: what to do?

It's worth noting an important factor right away: if the buzzing starts to appear when you run games or programs that overload the OS, this is normal. In this case, you don't have to worry. But if a laptop runs a small number of the most standard programs, and the device begins to hum strongly, then you should pay attention to this nuisance. We offer the most optimal ways solutions.

If you know exactly why the fan in your laptop is humming and it is overheating, then you need to find out whether you are operating the device correctly. For example, if the laptop is always on a soft and uneven surface (carpet, sofa, blanket, etc.), then the noise indicates that the ventilation holes are blocked, and thus the gadget is actively fighting for its existence. In order to completely eliminate the phenomenon, it will be enough to simply keep the product on a hard and level surface all the time - so that air is supplied to the radiator.

It is also worth noting the fact that special stands for laptops are becoming increasingly popular - they already have a built-in cooler.

Another effective way- This is cleaning the product from dust accumulations. One point needs to be taken into account here. If you are not sure that you can disassemble the device yourself, while the laptop is under warranty, it is best to take it to service center. There, experienced professionals will do all the work quickly and correctly, and you will be able to avoid sad consequences.

If you are sure that the fan in your laptop is making a loud noise due to dirt, and you know that you can carry out partial disassembly yourself, then we recommend taking a number of actions:

Turn off the laptop, disconnect the adapter and take out the battery.
Unscrew the screws that you will see on the back panel. In some laptop models, such screws can be hidden under special rubber feet - you need to carefully pry them off with a sharp object to get to the screw.
Remove the lid - this must be done very carefully.
Using cotton swabs, carefully remove dirt and dust from the cooling system.
Fine dust can be blown away. Or buy a special can of compressed air in advance - similar products are sold in computer stores.
After all the work is completed, you need to return the cover to its place and tighten the screws.

BIOS update

If even cleaning did not help eliminate the problem, then the problem may be due to incorrect settings. Sometimes such phenomena occur, and they are easy to eliminate. You need to find it on the official website new version BIOS, in which all errors will already be corrected. Your task is to download it.

Is the laptop fan making noise, although previously its operation was so noticeable that you were not aware of its existence? Then it’s time to contact our specialized service center - experienced technicians will diagnose it directly at your home and offer methods to solve the problem.

Why does noise appear? The answer to the question lies in the cooling system.

Generally, a laptop becomes noisy when the internal temperature rises. Overheating caused by contamination not only slows down the computer's command processing speed, but also poses a serious threat to the processor, one of the most expensive parts of the PC. When the internal part heats up, the temperature sensor is triggered, the cooler makes a lot of noise as it starts to operate at high speeds.

But a dirty cooling system is not always the answer to the question. Why is my laptop so noisy?. The cause may be bearing wear, which causes radial runout on the rotation axis. The impeller touching the cooler elements makes unpleasant sounds (rustling, grinding, crackling).

If the laptop is very noisy: purge

If your laptop is making a lot of noise, the best solution would be to contact a service center, where specialists will identify the exact cause of the problem. At home, you can do purging using:

vacuum cleaner switched to blowing;
a can filled with compressed air (sold in a specialty store).

Blowing should be done on the balcony in dry weather to avoid the “dispersal” of dust accumulated inside the housing throughout the apartment and accidental entry of moisture inside.

The cooler will be quieter after the procedure if the cause of its hum was contamination. In any case, cleaning with a jet of air will buy you some time (for example, to complete current work). After some time, you will again notice that the fan is making a lot of noise. Therefore, the sooner you contact a specialist for “ spring cleaning", which includes not only removing contaminants, but also replacing thermal paste, the better.

The cooler in the laptop is noisy - cleaning and lubrication

We have already figured out why the cooler in a laptop makes noise. If you know how to properly clean the cooling system, you can do it yourself. Don't forget that:

cleaning on your own may void the manufacturer's warranty;
it is necessary to act extremely carefully, avoiding pressure on any elements;
Before removing the radiator, it is necessary to warm it up. Why - because it is necessary to soften the old thermal paste;
The cleaned surface must be degreased before applying a new layer of thermal paste.

If the fan makes a lot of noise, you can try to lubricate it by removing the sticker and dropping lithol into the hole. Oil is also suitable for sewing machines or weapons. However, it should be noted that if a part is worn out, lubricant is useless - only replacing it will help.

The cooler in the laptop is very noisy - prevention and recovery

So, we figured out why the cooler in a laptop makes a lot of noise. Any extraneous sound, which occurs during operation, serves as a signal of certain problems, so the optimal solution would be to call the service center.

The cost of services from ProLaptop specialists is low, and the quality of work is impeccable. By contacting us, you will save time and avoid the risk of damage caused by careless handling.

complete dust removal;

Our specialists are ready to carry out preventive or restoration work at your home or office in Moscow. If the cooler in your laptop is very noisy, call, send an online request or order call back— we guarantee that you will be satisfied with the quality of our services.

In this article, you will learn what to do if your laptop makes a lot of noise, which not only reduces the comfort of work, but also creates an alarming feeling that something is wrong with the computer. It contains all possible reasons, along which the laptop cooler begins to rotate more actively, their signs and possible options eliminating the sources of the problem.

Advice. The term “noisy” means increased noise emission from the cooling fan. CPU. Noise hard drive not considered.

If the device is several years old from the date of purchase, and its operation is accompanied by increased generation of noise that occurs due to the accelerated rotation of the cooler, this is a reason to think about it.

During long work under heavy load increased speed ventilators are the norm. The processor processes large amounts of data (3D games), which causes it to heat up more, and to prevent it from overheating, the system automatically increases the fan speed. By the way, if you are faced with the “cpu fan error” problem, we have a separate material on solving it.

So if you watch movies in high quality or play games, appearance loud noises This is somewhat normal, especially after operating the device for several hours. It's another matter when the problem appears immediately or a few minutes after the device starts.

Is high cooler volume bad?

In addition to feeling discomfort and thinking that something is wrong with the laptop, increased noise from the CPU cooling fan is a sign of significant heating or overheating of the CPU.

And the operation of any components at elevated temperatures, for which they were not designed to operate or were designed for short-term exposure to such conditions, causes their faster wear. And this is in best case scenario. At worst, the computing device will simply overheat and fail.

Modern laptops have implemented a mechanism to protect the PC from such cases - when it reaches critical temperature the device simply turns off in emergency mode.

Causes of strong fan noise

In fact, the only source of the problem is increased operating temperature central processor. And there can be many root causes for its overheating. The main one is clogging of the heat-removing metal tubes (radiator) with dust and other small particles (lint, hair, wool).

Due to the fact that the airways through which air passes are partially blocked foreign objects(let's call dust and other small debris that way), the hot air flow diverted from the central processor is partially dissipated, hitting the radiator mesh.

There are several solutions to the problem:

increasing the cooler rotation speed;
purging or cleaning the cooling system;
replacing thermal paste, lubricating and/or replacing the fan.

How to solve the problem in the case of each of the options will be discussed below.

High temperature

Signs that high temperature is the culprit of loud noise

In principle, increased processor temperature is the main culprit of noise. And there are several explicit and indirect confirmations of this.

Applications that display data from computer sensors – SpeedFan, HWMonitor. In them you can find out the current and maximum temperature recorded during the application’s activity and compare it with data on the processor’s operating modes on the website of its manufacturer.
The noise appears some time after starting a game or playing a movie (performing another resource-intensive task).
A very hot case in the area where the CPU is located and where the hot air flows out from it.
The device works slower, freezes, slows down, and sometimes turns off or restarts without permission.

Changing the fan speed

Let's consider what to do if the laptop makes a lot of noise when processing large amounts of information, for example, converting video, packing/unpacking something, installing or running games, watching movies in HD and similar cases.

This is done via UEFI (in some old BIOS a similar function is also present), and through a special software, for example, SpeedFan. The advantage of the utility is the ability to control the speed of fans installed on GPU and displaying temperature trends of key hardware components.

By manual change The initial fan rotation speed in 5% increments can be either lowered if the device is very humming without load or overheating, or increased when the CPU temperature is close to critical or simply increased.

Rice. 1 Adjusting the cooler speed in SpeedFan

Unfortunately, the application is not updated often, which is why it may not be supported by some new products on the laptop market, and is also not compatible with a small percentage of computers due to the specificity of their hardware shell.

Controlling the fan speed in BIOS/UEFI is no less simple, but in each firmware version from each manufacturer this parameter may be called differently and located in different submenus. The instruction manual or your own ingenuity will help here.

Blowing out the cooling system

If the first option does not solve the problem, or rather it is caused by dust and small specks stuck to the cooler blades and radiator mesh, then we move on to the option of purging the cooling system. This is done in several cases:

when the device is still under warranty, and it is not advisable to void it by disassembling the case for cleaning;
the user does not have the skills to disassemble laptops or is afraid to do so, and going to a service center is not a solution.

In this case, you will need a special canister filled with compressed air (sold in specialized stores) or a powerful vacuum cleaner, preferably turned on for blowing (reverse). In extreme cases, a hair dryer will do, but its effectiveness will be extremely low.

We take the device with a spray can or vacuum cleaner to a balcony or other room that you don’t mind getting dirty with dust. This should be done in calm, dry weather if the procedure is carried out on an unglazed balcony or in the yard. After several blows with a stream of air, the laptop can be turned on and tested.

It happens that blowing does not bring almost any benefit, or a few months after it the laptop begins to hum just as loudly. Then you will have to unwind it and thoroughly clean both the cooling system itself and get rid of dust under the back cover of the case.

How to quickly and easily clean your laptop from dust with a vacuum cleaner?

Let's consider a simple household method of cleaning a laptop using a vacuum cleaner, so to speak, at home. We'll also look at why it's important to clean your laptop and how to determine if it's worth cleaning.

Removing dust

You should undertake this when you are sure that you will successfully disassemble the laptop case without breaking its fasteners, carefully follow all the recommendations below, and disassembling the case will not void the warranty (it has already expired). To remove small dust particles you will need:

screwdriver for unscrewing bolts;
preferably a kit for opening laptops and other equipment (if you don’t have one, you can use improvised tools);
a couple of napkins, a piece of cloth, cotton swabs or something similar;
vacuum cleaner, cylinder compressed air or hair dryer (optional).

The sequence of actions for removing dust will be as follows.

We disconnect the laptop from the network and remove the battery from it.

Rice. 2 - Remove the battery

Disconnect all wires and external devices.
Unscrew the bolts of the back cover.

Advice. You should be careful here: the bolts may be under stickers or rubber feet.

Rice. 3 – Filming back cover

We remove the entire back cover or the segment where the processor with the entire cooling system is located.

Advice. If you do not have tools for disassembling tablets/laptops, find a replacement and carefully, so as not to damage various latches, disassemble the case.

Using fabric, cotton wool, or simply by hand, we remove large pieces of debris, often compressed or welded together.

Rice. 4 – Remove dust from the blades

Advice. Remaining dust can be blown off using an air can or a vacuum cleaner. When there are no such devices, carefully remove them using a napkin or cotton swab. If you want to blow off the dust, do it outside or in a utility room.

If tiny air ducts in the radiator mesh are clogged with dust, the cooler and radiator can be unscrewed and thoroughly cleaned one by one.

Rice. 5 – Remove the cooling system

Carefully assemble the laptop, performing all steps in reverse order.

Cooler maintenance

At the point of contact of the radiator with the surface of the processor, a special substance - thermal paste - with high thermal conductivity is applied. It removes excess heat from the CPU to the radiator, which is cooled by a fan by removing hot air outside the case. Over time, thermal paste loses its properties and copes with its intended functions worse, and it has to be replaced.

You can do this yourself.

As in the case of removing dust, we disassemble the laptop, letting it work a little or warming up the processor area with a hairdryer so that the thermal paste becomes more viscous.
We remove the cooler and carefully disconnect the radiator from the processor, if necessary, heating the place of their contact.

Rice. 6 – Remove cooling

Carefully clean the contact pad from any remaining thermal paste.

Rice. 7 – Removing residual thermal paste

We degrease the surfaces with an alcohol-containing substance (cologne) and let them dry completely.
Apply a thin layer of new paste from the tube, using a syringe or plastic/cardboard.

Rice. 8 – Applying thermal paste

We put back the radiator with cooler.
Putting the body back together.

The likelihood that the problem will be completely eliminated here is small, but periodic replacement of thermal paste once every year or two is necessary.

How to replace the thermal paste of the processor and video card on a laptop?

If you are interested in how to replace the thermal paste of a processor and video card on a laptop, then this video is for you. In it, I briefly, bypassing the obvious and understandable steps for everyone, explained how to do this after disassembling the laptop.

Fan repair/replacement

The last thing that can help the user is replacing or restoring the cooler. Over time, the ball bearings in it can wear out or the lubricant in which they move can be depleted. Try to remove the back cover of the case in order to get to the cooler, and drop a thick lubricating fluid: grease or lithol into its center (usually you have to tear off the sticker). If this does not help, a possible scenario would be to purchase and install a new cooler. The need to replace it may be indicated by:

the fan grinds throughout its operation;
the cooler does not rotate at the slightest touch of a finger;
The device is wobbly or loose.

Advice. If you are not confident in your strengths and abilities, contact a specialized center for help in cleaning your laptop from dust, replacing thermal paste, cooler, or repairing it.

And finally, a recommendation: to improve the cooling of your laptop, you can purchase a special table-stand with a built-in cooler, which will not only make work more convenient, but will also blow cold air from below the case.

Is your laptop overheating, slowing down and turning off? How to disassemble and clean a laptop from dust?

In this video, we explain why a laptop overheats, starts to slow down, and even shuts down. The whole problem is one thing - the cooling system is clogged with dust. This causes the laptop, that is, its processor and video card, to get very hot, and to prevent a malfunction, the processor and video card frequencies are lowered so as not to heat up even more. And, of course, here we tell you how to clean a laptop, change thermal paste, and in general how to disassemble it.

A guide to reducing noise levels from a laptop, netbook, computer and others similar devices. The manual also describes how you can extend their service life.

General information about noise, what makes it and why it needs to be reduced

The vast majority of current technology produces a variety of noises during operation. They can be very different: clicks, thin squeaks, hums, and so on. Let's first figure out where they come from and what publishes them.

The main source of noise is the cooling fan. The faster it rotates, the stronger and higher in pitch the rumble from its operation. If the fan's bearing is worn out, the hum becomes much stronger due to the imbalance of the impeller with the blades. Dust accumulation on the blades also increases noise levels and also accelerates bearing wear.

The second source of noise is the drive optical disks And hard drive. The optical drive makes a fairly loud noise. The higher the rotation speed of the disk and the less balanced it is, the stronger the hum. The Winchester also makes a hum, but it is much quieter. The hard drive also makes clicking noises from time to time. This is due to the fact that there is a magnetic head unit inside the hard drive. He moves very quickly, jerkily. This is how clicks are made.

So we went over 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 your work. Few people would like to work behind a device that hums like a vacuum cleaner. In addition, many people leave laptops and computers overnight to download. Excessive noise interferes with sleep.

A less obvious reason is increased wear on components. It is logical that if the fan rotates faster, the bearing that holds the impeller with the blades will wear out faster. Not everyone will like the prospect of changing the fan every 1-3 years. It's a similar story with the hard drive.

We figured out why to reduce noise. It remains to find out how it can be reduced. This is what this guide will cover. First, let's look at how to reduce fan noise, and then how to make the hard drive clicks quieter.

Reducing fan noise

Important notes on disassembling the laptop:

Before disassembling the device, mandatory disconnect the battery and power supply;
When disassembling, it is highly advisable to use an antistatic wrist strap and a mat;
In addition to bolts, plastic parts of laptops are often held in place by latches. You need to be careful with them;
In many laptops, access to 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. Acer Aspire laptops;
The bolts in laptops are different. They can differ 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 be alarmed, there's actually nothing complicated about it.

Our goal is to get to the fan. Unscrew 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 others, to remove it you must first remove the lock washer on the other side of the fan. Often this washer is located under a plug. Let's look at this whole process using the example of a regular computer fan. In laptops, the fan has a completely similar design. First, remove the sticker above the plug, and then the plug itself:

Handle the sticker carefully. We still have to stick it back on.

That's how we got to the retaining ring. It fits into a groove on the shaft and has a small cut along the radius. We pry it with something sharp and carefully remove it:

So we removed the impeller:

Now you need to thoroughly clean it with a napkin or dust cloth:

After this, you need to remove the old grease from the impeller shaft and fan bearings. For better removal It is recommended to use alcohol or other solvents. If you decide to use acetone, you should keep in mind that not all plastics tolerate it well.

After removing the old lubricant, you can proceed to applying a new one. In our case, it is best to use bearing lubricants. When choosing a lubricant, it is worth considering the number of revolutions per minute. For our purposes, lubricants that are designed for rotation speeds of up to 5-10 thousand revolutions per minute are suitable. Some lubricants have protective and restorative properties and can compensate for slight wear of fan bearings. They can be easily found in auto parts stores.

If you do not find the above lubricants, you can use silicone, synthetic, mineral, and machine oils. Since most fans do not contain proper seals to hold oil in the bearing, it is not recommended to use oil that is too thin.

IN in this example I used Hado protective lubricant. Lubricate the bearing and fan shaft:

At the same time, you can clean the laptop radiator from dust and other debris. In a not particularly advanced 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. Fan bearing wear in this case is also much higher. After cleaning, the radiator looks something like this:

Now you can put everything back together. If after some time the fan begins to hum again, this indicates severe 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 (indicated on the back of the fan) at various online auctions. You can also contact the service center.

Let's now consider how to reduce the noise level of a hard drive.

Reducing the volume of hard drive clicks

Another source of noise is the hard drive. As mentioned above, clicks when fast movement block with magnetic heads. Therefore, to make the 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 drive. However, there are also disadvantages: when the speed of movement of the heads decreases, the search time increases slightly. For most tasks this will not be noticeable.

Let's now figure out how to reduce the speed of movement of the head block. Fortunately, everything has already been thought out for us. Hard drive manufacturers invented such a function as: AAM. Changing the parameter value A.A.M., 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:

When launched for the first time, the utility checks whether the value can be changed A.A.M. And APM. Right-click on the utility icon near the clock. Select from the menu Settings:

In the settings go to the tab AAM Settings and move the sliders to the left. The top one responds and the bottom sliders allow you to control A.A.M. when the laptop is plugged in or running on batteries.

You can also go to the tab Manual Settings for testing, move the slider A.A.M. left and press the button Set AAM Value:

On the tab Misc. Settings check if the checkbox next to Enable AAM Control:

Click on Apply

Let's check if the utility works. Right-click on its icon and look at the line with AAM at the top:

The AAM value actually dropped to 128, and the hard drive began to work a little quieter.

There is one more small detail left. To make the hard drive work less noisily (with a lower value A.A.M.) it is necessary for this utility to work 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.
