Why laptop begins to make noise. Laptop noise: Possible causes and ways to solve them

It often happens that the owner of the laptop worries noise during the operation of the device. At the same time, as a rule, if the laptop computer is new, then most likely, everything is in order with him, and it's noise because it works: inside the case the fan blades rotate and create noise.

At the same time, two externally differ portable computer differing from each other may be noise differently. In many respects, it depends on the size and size of the blades of the fans (coolers). In addition, the design of the cooling system, as well as the power portable device. Usually, more productive and fast laptop noise is stronger.

Why is a laptop, which is more powerful?

Because when it works more heat, the cooler blades are forced to spin faster. But all this applies to new devices. If you use your computer for a year or two, and he began to make noise more than usual, the question is why this happens is relevant. If the noise is enhanced with a high load of the operating system, that is, when you watch the movie, play the game or run any program, then, most likely, you just need cleaning the laptop from dust, it is done high quality.

It is described below why in 90-95% of cases in a strong noise, dust is to blame, and that can still cause similar problems.

Why is a strong noise bad sign?

If the laptop computer is noise stronger than usual, it means that the temperature inside the device rises above the norm, the cooling system does not cope with its functions, and the cooler has to work at the limit of the possibilities.

It is very bad not only and not so much for the fan itself: work at elevated temperature significantly reduces the service life of expensive chips. When due to overheating burns out some chip on motherboard, for example, a video card, then its repair is much more expensive than cleaning the dust, which has already been mentioned, and which, with timely conduct, relieves the problem of noise and warns serious breakdowns.

How to understand why the laptop is noise?

Depending on the origin, the noise arising when the computer operates can be divided into 2 types:

1. Electric noise. These noise occur during the operation of capacitors and other parts of the computer, for which the current passes. Electric noise is characterized by a characteristic sound - periodic crackling, which can sink, disappear to change its character or intensify. If you hear such crackles from the moment of purchase, and they do not intensify over time, then most likely there is no reason for concern, everything is in order with your laptop computer. Remember that with a large load noise can be more intense or weaker.
2. Mechanical noises. In this article, we are talking about mechanical noise. Thus, everything that will be described below belongs to the mechanical noise and ways to eliminate it. One of the main reasons for such noise is dust.

Why if the laptop is very cozy, then we can assume that a lot of dust accumulated inside the computer?

Because small particles falling inside mobile device Together with the air from the fan blades, it passes through the grille of the cooling radiator and partially settles on it. Over time, the dust accumulates and begins to create an obstacle to the flow of coolant. If the cleaning is not performed on time, the fan begins to work at a higher speed in order to maintain the normal temperature inside the device, and the faster rotation of the blades leads to the fact that it is stronger than noise. It is from such mechanical noise that regular prophylactic cleaning of a laptop from dust 95 percent of cases helps to get rid of dust.

It is important to emphasize that a cooler will be harder to make on the limit loads of the device even when the air supply to the radiator grille is not difficult.

When does the cooler work more intense?

It is possible to understand how bad the cooling system is possible by learning the temperature of the most loadable components - processor and video cards. This is done with the help of special programs, such as HWMONITOR. In a state of waiting, that is, when only one is running operating system And the processor is not loaded by no more than 50%, the temperature of the working chips should not exceed 65-75 °. And when loading the processor, the maximum power T ° should not be higher than 90-95 °. You can see the degree of workload of the processor in the Task Manager. If T ° rises above and at the same time no laptop is stronger than usual, then the likelihood is that the cause of the noise is clogging the cooling system.

But even if the temperature does not exceed the above values, this does not mean that there are no dust on radiators. The fact is that the norms of measured indicators are averaged, and concern only critical maxima applicable to all devices. And individual norms of working temperatures different models Laptop computers can differ significantly. Therefore, if the fan goes stronger than usual, the cleaning of the dust laptop is shown even when, according to measurements, the temperature is below the maximum allowable values. On average, modern productive apparatus, depending on the model, cleaning is needed at least 1 time in 1-2 years.

How to understand the reason in dust or not?

You can think about it when when you load, for example, when watching a movie, communication in Skype, etc. The computer is suddenly disconnected, and before that, warning inscriptions or signs indicating the error do not appear on the screen. This happens because because of the pollution accumulated on the radiator, the processor and the video card do not have time to cool to normal temperature and triggers automatic system protection. If, before turning off, error messages appear on the screen, it is likely that it is not in dust and not in overheating.

Cleaning a dust laptop You will need if the body of the device becomes hot during operation.

If the cooler is noise loud and constantly, and before the device worked differently.

1. If you are bothering not only what a laptop is buzzing, but also the fact that he has become bad to work: the computer slows down and constantly hangs, and you want to know why this happens. Most likely, the fact is that the temperature of intensively working components rise above the norm, and the protection system reduces their speed, so the device begins to work slower. To understand that the reason is precisely in this, and you can help clean the laptop from dust, measure the temperature inside the computer at the time of hang, using the HWMonitor program. If t ° will be above 90 °, then carry your computer into cleaning, if below 75-85 °, then, most likely, the cause of braking is software.

If the fan is buzzing unnatural?

First of all, it must be said that the coolers are very rarely faced and require replacement. Usually in time the cleaning of the laptop from dust and the fan lubrication allows you to solve all problems. By the nature of the sound, it is possible to determine how serious the violations in the work of the cooler. If the laptop is noise strongly, but evenly, monotonously, then the usual prophylaxis will help to get rid of this noise.

However, if the noise is uneven and accompanied by grinding and tapping, then this is an unpleasant feature. In 50% of cases, the fan lubricant with this character of the sound can be corrected, but it may well be that a unnaturally buzzing fan will have to replace the new one. Such a replacement is 2-3 times more expensive than ordinary prophylactic cleaning, so first try to remove the blockage and, if necessary, lubricate the cooler.

Why not always lubricate the fan?

Because in this case, the cleaning of the laptop from dust may be the only necessary action: after it the operation of the cooling system is normalized, and the laptop ceases to buzz. However, if it did not remove the problem, and the uniform noise is saved, then you need to try to lubricate the cooler: in 50% of cases it can help.

It is important to understand that without the experience of such work, self-cleaning of a laptop from dust can lead to his breakdown. And if you have never been doing this before, then it is best to immediately take the device in service centerAnd the procedure itself will cost several times cheaper than replacement randomly damaged due to the lack of skill of expensive components.

Today's question

Good day.

Tell me, I have a problem with a new laptop (he is 1 month). At night clearly hear the light hum when you run wot. game (Tanks) - Gul's volume increases, and with time the laptop is buzzing already as a tractor! It strains me very much, because It happens that relatives are already sleeping (and I get it difficult to ...).

Is it possible to somehow reduce the noise? For guarantees, I can't pass the laptop no longer, more than 2 weeks have passed after buying a device (it happened that I did not check the device completely, because I was leaving).

Alexey, Moscow.

Hello.

Alexey, I immediately want to say that noise-noise mint. Moreover, if there was no noise earlier, and now it appeared - this can signal the appearance of hardware problems with the device. In your case, most likely, when buying, you simply did not pay attention to the features of the laptop. Nevertheless, something can still be done.

In this article, they will raise the main reasons because of which the laptop may be noise, and what can be done with it ...

Immediately I want to say that in a laptop, much less mechanical devices were rather than in a PC, from which there may be noise. On the one hand, this fact helps to determine the source, on the other - in view of the compactness of the device is not always easy to eliminate the cause ...

Cooler. Probably the largest source of noise that is in most classic laptops. As a rule, if you do not load a hard device (i.e., you do not run games, viewing high-quality video, etc. Tasks) - then his work is almost silent. Although a small buzz is heard on some laptops, if you get closer to the side ventilation holes on the device case.

HDD. The most cunning source of noise. First, some models can easily skip and crack during operation (some models do it under load). You can only hear this noise in full silence (i.e., at night in silence, 100% will be annoyed). Secondly, it is not warranty caseAnd in replacing the device for this reason will refuse you.

Also, at high load on the disk - can be heard as soon as a noticeable hum may be heard, like a cooler noise.

CD | DVD drive. It makes sufficiently strong noise when working: it goes like a root from the rotation of the disk and light crackle. By the way, many users simply forget to remove discs from it, and the laptop often spins the disk in the tray and noise appears.

Cause №1: Cooling system is clogged (if the cooler tahar)

Perhaps the most basic reason for which begins to bury it hard (or as many people say "taural") cooler is a large dust cluster that closes the ventilation holes, accumulates on the impeller and interferes with normal air circulation.

Due to dust, the cooling system does not cope with the load, the cooler begins to work faster, and as a result, noise increases.

Dust cleaning of the laptop Depends on its configuration. Some laptops will not be difficult to clean on their own even for a very novice user, others - to get to the cooler it will need to disassemble the entire device!

Therefore, look here: either in service, or an attempt to try to do everything on your own. His soaps and recommendations, how to do it, led in one of the articles (reference below).

Detail how to clean the laptop from dust on your own -

In general, 1-2 times a year is extremely desirable to led the cleaning of the device and remove excess dust. Not excess with this procedure will lubricate the cooler. If the inches of the impeller, periodically assisted about the housing (for example, it can be damaged during non-accurate cleaning) - it is easier to replace the cooler completely.

cleaning the impeller with a cotton wand

Reason # 2: High temperature and laptop load

Perhaps this reason partly intersects with the first. The fact is that the laptop cooler works dynamically - i.e. rotates at different points in time with different speed. The higher the temperature of the processor and the load above it is the load - the faster the cooler begins to rotate, in order to cool down more and time to divert heat. And such a work of the cooler in turn leads to the appearance of a hum and noise from a laptop ...

By the way, during this Gruty, when the cooler works at the limit, as a rule, hot air begins to go from the ventilation holes of the laptop. The keyboard can also become warm, it may not be comfortable to work (especially sin acer laptops on AMD processors).

And so, how to find out the temperature of the processor, the video card in the laptop?

The easiest way is to use special utility - AIDA64 (reference to it is given below). To view the temperature of all components (CPU, video cards in AIDA64 hard disk etc.) - go to the tab "Computer / Sensors" .

The best utilities for viewing the characteristics of the computer (including AIDA64) -

Its modest view about what temperature I consider normal, and when you need to do something, told in this article: . I recommend to get acquainted!

1. use a laptop only on flat, dry, solid and clean surfaces (and many use a laptop lying on the sofa - and because of this, the ventilation openings may be overlap, which leads to overheating);
2. regularly (1-2 times a year) to clean the device from dust;
3. if you like to play games (as well as beam by heavy applications: video and graphic editor, etc.) - purchase a coolant coolant for a laptop. It is a way to reduce the temperature of 5-10 degrees (though pay attention, some of them are noisy ☺);
4. look, is not related huge pressure On the CPU with something else, and not only with the launched game (I recommend to get acquainted with this article :);
5. also B. manual mode Customize the speed of rotation of the cooler (carefully! Do it step by step, does not hurry and watching the temperature) -
6. it is possible to disable Turbo Boost. And hold undervolting. This allows reduce the temperature of the CPU by 10-20 ° C. How to do it here:
7. if you have very hot outside the window - try not to use a laptop in the sun, if possible, load it in the morning, evening hours when the temperature becomes below.

Reason # 3: Gul, crackling and handling from hard disk

Some models hard disks With its work, they make mechanical noise: cracking and skidding. If the room is very quiet - then these clicks are very annoying. There is a similar due to the rapid movement of the block with magnetic heads. Running forward will say that the speed of movement can be reduced due to which noise will decrease ...

How to reduce the noise level from the disk:

1. replace the disk to another (which is not noise). The best way: Installing an SSD disk () - He is a priori silent, because There are no mechanics in it, besides, such discs are much faster! Comparison of the SSD disk and classical HDD, presented in this article:
2. check in task Manager (To call it - press the Ctrl + Alt + Del combination) - there is no application that loads your disk strongly (most often these are torrents, P2P programs for downloading files);
3. reduce head positioning speed using QuietHDD and HDDScan utilities. On how to do this, see this article -
4. if you have before hDD no noisy, and now began - this is an alarming symptom, I recommend checking the HDD -

Cause # 4: Forgot to remove the CD | DVD drive from the drive

CD / DVD drive is in many computers and laptops (although it does not put it at all). Because This is a mechanical device (like HDD) when the disk is promotion (especially for maximum speeds), it begins to buzz. Noise from it is stronger than from the actively working cooler.

If you forget to remove the disk from it - then each time you open the conductor (folders) - the drive will spin the disk, trying to provide you with information. As a result, noise will appear, and for 1-2 seconds. The computer will hide ...

I will give below what can be done and the reasons why the CD / DVD-ROM drive makes noise:

1. check if there is scratches on the carrier (disk), it is smooth? The victim disks are no longer no more;
2. you can try to install specials. utilities that can limit the speed of rotation of the disk, for example, Nero Drive Speed.;
3. try to insert different discs: CD-R, CD-RW, DVD-R, etc. I also recommend trying to use licensed discs of a known brand, and not purchased in the transition in an unknown counter;
4. if there is a label on the disk - then the reason for it is possible, it can be unevenly applied (some thick labels can also affect the noise level of the drive);
5. noise in the drive may appear due to foreign objects, for example, a piece of a sloppy disk (if you did not have this, didn't you get into the drive?).

Cause No. 5: Not optimal BIOS work and drivers

Many underestimate the work of BIOS and drivers, meanwhile, they can have a big impact on the work of the laptop. As for noise - how you probably have already noticed - the cooler in the device works dynamically, i.e. The higher the load and temperature, the faster it rotates. This mode is enabled by default in BIOS laptop (Sometimes it can be customized, sometimes no). It is usually called: Q-Fan, CPU Fan Control, Fan Monitor, Fan Optimize, etc.

In some versions of bios. This cooler adjustment mode works out of hand bad - i.e. The cooler works much faster than it is required at the moment. In consequence, there are constant noise and hum of it (regardless of the load).

There are a couple of ways: Try to update BIOS (Caution! When updating - you can easily spoil the performance of the device) on more new version (if it is on the manufacturer's website).

Second output: Disable automation mode to BIOS and customize the operation of the cooler yourself with the help of specials. utilities. View an example, as is done, you can in this article:

I hope my modest advice helped get rid of "loud" noise and calm the nerves ☺.

For additions to the article - a separate MERSI.

On the sim all, good luck!

Greetings to you, dear readers!

I think that the problem is that the fan in the computer or laptop is buzzing, met many of you.

Noise is a completely normal effect when operating a computer or laptop.

It is called by the rapid rotation of the fan in the cooling system, but usually such noise does not cause suspicion about the presence of a problem.

If the noise of the fan is very loud, and it is possible even to hear distinct knocks or friction during the work, then this article is for you.

Culera Noise: The fan buzzes in a nubuk - what to do?

The cooling system of the laptop consists of several elements.

Fan, radiator and ventilation holes on the laptop housing are the elements of the cooling system.

Noise can be caused only by one part of the cooler - its fan, since only it makes mechanical movements.

The reasons that can cause noise can be different, but they are all in one place - in the laptop cooler fan.

For example, you could not clean your laptop, which led to a large cluster of dust inside the laptop, including inside the cooling system. And often, for this reason, in a laptop the fan works constantlybecause it does not cope with the cooling of parts.

This dust creates interference to rotate the fan, which increases its temperature and can lead to severe overheating and further damage to the fan.

To clean the laptop from dust, it is necessary, first of all, to disassemble it ...

If you are not familiar with the process of assembling a laptop, I advise you to find knowledgeable peoplethat you will help you, or give the Center to the service.

If you know how to disassemble a laptop, then you probably know that in most models, the cooling system is in the "end" of the disassembly process.

Reaching the cooler, it is necessary to disassemble it, clean the inner wall of the radiator from dust, blow the blades and clean them with a brush.

Example cooler before cleaning

After cleaning.

After cleaning the cooler from dust, it is advisable to smear the fan bearing!

To do this, it is necessary to rejuvenate a protective sticker, there will be a small hole leading to the axis of the motor, as well as to the bearing part.

Hole closes a rubber plug. In order for the oil to fall into the right place, the cork should be either removed, or pierce the syringe in which the lubricant is located.

Lubrication is better to use silicone or motor oil, because Rotation occurs quickly, and such lubricants will not be strongly extended during operation and provide good slip.

The place where it was glued to glue, you need to clean well and instead of sticking tape. This is done in order to avoid leaving the lubricant outside.

After lubricating and cleaning, it is worth allowing a little laptop to stand up, about 20-30 minutes, and then include and check.

If after such procedures, the noise continues, then cooler should be replaced.

To do this, it is necessary to know his model - often it is written on the sticker that was pasted on the cooler.

The cost of coolers varies, for example, I bought a cooler for laptop asus K55d for about 800 rubles, taking into account delivery.

If the fan is noise in the computer system block

In fact, the source of the problem is the same as in the laptop.

Only two things are distinguished.

The first - Maschat works - coolers in the system unit are slightly more, and also differ in the design of the radiator, but the principle of operation is the same.

Power supply cooler

The second is the number of coolers - in the system unit there are several coolers and before working to eliminate noise, it is worth determining which of them is noise.

Cooler video card Cooler processor

To do this, remove the side cover system BlockAnd then a finger, or with a cotton wand carefully stop the coolers in turn, where the noise was disappeared - he is not well.

After determining the problem fan, disconnect it from the place of attachment, clean it and the radiator, lubricate the fan, put in place.

After 20-30 minutes, we start the system unit.

Noise stayed? The replacement of the cooler is inevitable, but it is easier to find it on a computer than on a laptop.

That's all!

The noise of fans is an unpleasant problem, since the faulty cooler can lead to stamina damage to the parts during overheating.

The sooner you notice the availability of problems, the smallest the consequences of overheating, since any malfunction inside the cooling system leads to strong temperature increases in the cooled part.

All the best, friends!

In the proposed article, learn what to do if the laptop is very cozy, which is not only the comfort of work decreases, but also an alarming sensation arises that something is wrong with the computer. It contains all possible reasonsFor which the laptop cooler begins to rotate, their signs and possible options for eliminating sources of malfunction.

Council. Under the concept of "noum" hides an increased noise of the fan, cooling the central processor. Hard disk noise is not considered.

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

During long-term operation, with a significant load, high fan turns are the norm. The processor processes large data arrays (three-dimensional games), which is hot, and so that it does not overheat, the system automatically increases the frequency of rotation of the fan. By the way, if you encountered the problem of "CPU Fan Error" we have a separate material by solving it.

So if watch movies in high quality Or play games, the appearance of strong noise is partly the norm, especially after several hours of operation of the device. Another thing is when the problem appears immediately or a few minutes after the device is started.

High volume of the cooler is bad?

In addition to the sense of discomfort and thoughts that something is wrong with a laptop, the increased noise from the cooling central fan processor is a sign of a fair heating or overheating of the CPU.

And the functioning of any components at elevated temperature, to work at which they are not created or are designed for short-term stay in such conditions, it causes more rapid wear. And this is at best. At worst, the computing device simply overheats and fails.

In modern laptops, a PC protection mechanism from such cases was introduced - when the critical temperature is reached, the device simply turns off in emergency mode.

Causes of the strong hum of fan

Actually a single source of problem is increased working temperature central processor. And the root cause of its overheating can be many. The main is to clog the heat sink metal tubes (radiator) dust and other small particles (pile, hair, wool).

Due to the fact that the airways for which air passes partially overlapped with outsiders (let's call dust and other small garbage so), hot, diverting from the central processor, the air flow is partially dissipated by hitting the radiator grid.

There are several solutions to problems:

• increasing the speed of the cooler;
• purge or cleaning the cooling system;
• replacing the thermal paste, lubricant and / or fan replacement.

How to solve the problem in the case of each option will understand below.

Heat

Signs that the culprit of strong noise is high temperature

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

• Applications displaying data from computer sensors - Speedfan, HWMONITOR. They can be found in them the current and maximally fixed in the time of activity of the application temperature and compare it with the data about the mode of operation of the processor on the site of its manufacturer.
• Noise appears for some time after starting the game or play the movie (performing a different resource-intensive task).
• Very hot housing in the area of \u200b\u200bthe CPU location and the outlet of the hot air flow from it.
• The device works more slowly, hangs, slows down, and sometimes it turns off unimprovately or restarted.

Change the frequency of rotation of the fan

Consider what to do if the laptop is strongly noise in cases of processing large amounts of information, such as converting video, packaging / unpacking something, installing or operation of games, watching movies in HD and similar cases.

It is done both through the UEFI (in some old BIOSs also there is also a similar function) and through a special software, For example, Speedfan. The advantage of the utility is the ability to control the turnover of fans installed on graphic processor and displaying the temperature dynamics of key hardware components.

By manually changing the initial speed of rotation of the fans in increments of 5%, it can be lowered if the device is very buzzing without load and overheating, and increase when the CPU temperature is close in critical or simply increased.

Fig. 1 Couple speed adjustment in Speedfan

Unfortunately, the application is infrequently updated, which may not be supported by some novelties in the portable computer market, and is also not compatible with a minor percentage of computers due to the specificity of their hardware shell.

The speed control of the speed of the cooler in the BIOS / UEFI is not less simply, but in each version of the firmware for each manufacturer, this parameter may be called differently and located in various submenu. Here will help the operating manual or your own intelligence.

Bringing the cooling system

If the first option does not solve the problem, more precisely, it is caused by dust and small sroans, adhered to the coolers and grid of the radiator, then go to an option with purging the cooling system. This is done in several cases:

• when the device is still under warranty, and cancel it, disagreeing the body for cleaning, is not advisable;
• the user does not own the skills of disassembling laptops or fears to do it, and the campaign in the service center is not a way out.

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

We carry out a device with a canopy or a vacuum cleaner on a balcony or another room that will not pity to blur in dust. It should be done in a windless dry weather if the procedure is performed on an unlocked balcony or in the courtyard. After several blows of the air jet, the laptop can be turned on and test.

It happens that it does not bring almost any benefit or a few months after it, the laptop begins to all be very buzzing. Then it will have to be promoted and thoroughly cleaned as the cooling system itself, and get rid of dust under the back cover of the case.

How easy and quickly clean the laptop from dust with a vacuum cleaner?

Consider a household simple way to clean the laptop with a vacuum cleaner, so to speak at home. We will also consider why it is important to clean the laptop and how to determine whether it is worth it.

Dust removal

It should be taken for this when we are confident that we will successfully discern the case of a laptop, without breaking its mounts, carefully do all the recommendations below, and the analysis of the case will not lead to the cancellation of the guarantee (it has already expired). To remove small dust particles, you will need:

• screwdriver for unscrewing bolts;
• it is desirable to open laptops and other techniques (in the case of its absence, you can use undergraduate tools);
• a couple of napkins, a piece of fabric, cotton wands or anything like it;
• vacuum cleaner, compressed air balloon or hairdryer (optional).

The sequence of action to remove dust will be the following.

1. Turn off the laptop computer from the network and pull out the battery from it.

Fig. 2 - Remove the battery

1. Disconnect all the wires and external devices.
2. Unscrew the rear cover bolts.

Council. Here you should be attentive: bolts can be under stickers, rubber legs.

Fig. 3 - Remove the back cover

1. Remove the entire back cover or its segment where the processor is located with the entire cooling system.

Council. In the absence of tools for disassembling tablets / laptops, find them a replacement and carefully, in order not to damage all the sorts of latches, disassemble the case.

1. With the help of fabric, watts, or simply manually removing large pieces of garbage, often compressed, soldered.

Fig. 4 - Remove dust with blades

Council. Dust remnants can be blown away using a balloon with air or a vacuum cleaner. When there are no such devices, we carefully remove them with a napkin or cotton sticks. If the desire to blow dust, do it on the street or utility room.

1. If the meager ducts are scored dust in the radiator grid, the cooler with the radiator can be unscrewed and thoroughly clean the one.

Fig. 5 - Remove the cooling system

1. Gently collect a laptop, performing all actions in the reverse order.

Couple Service

At the place of contact of the radiator with the surface of the processor, a special substance is applied - thermalcaste - with high thermal conductivity. It removes the excess heat from the CPU to the radiator, and the one is already cooled using the fan by outputting hot air outside the housing. A thermalcaste eventually loses its properties and worse copes with functions laid on it, and it has to be replaced.

You can do it yourself.

1. As in the case of the removal of dust, we deal with the laptop, giving it a little to work or warming up the processor area with a hairdryer, so that the thermalcase has become more viscous.
2. We remove the cooler and carefully disconnect the radiator from the processor, if necessary, heated the place of their contact.

Fig. 6 - Remove cooling

1. Carefully clean the contact pad from the residues of the thermal paste.

Fig. 7 - Delete balance of thermal paste

1. Degrease the surface with alcohol-containing substance (cologne) and let them dry completely.
2. We apply a non-flame layer of a new pasta with a tube, with a syringe or plastic / cardboard.

Fig. 8 - applying thermal paste

1. We put back the radiator with the cooler.
2. We collect the housing back.

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

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

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

Repair / Replacement Fan

The last thing that can help the user is a replacement or recovery of the cooler. Over time, ball bearings can be caught in it or exhausted the lubricant in which they move. Try to remove the back cover of the housing, in order to get to the cooler, and drop into its center (usually you have to skip the sticker) thick lubricating fluid: solidola or lithol. If it does not help, the acquisition and installation of the new cooler will be possible. The need to replace it may indicate:

• the fan grinding throughout its life;
• the cooler does not rotate from the easiest touch of his finger;
• the device is staggering or backlash.

Council. If you are not sure about your abilities and abilities, for help in cleaning a laptop from dust, replace the thermal paste, cooler or repairs to a specialized center.

And finally, recommendation: To improve the cooling of the laptop, you can purchase a special table stand with an inserted cooler, which will not only make the job more comfortable, but will also be revealed to blow the housing with cold air.

Heats, slows down and turns off the laptop? How to disassemble and clean the laptop from dust?

In this video, we tell me why the laptop overheats, starts to slow down and turns off in general. The whole problem is in one - the cooling system is clogged with dust. The laptop is greatly heated, that is, its processor and a video card, and so that the failure does not happen in the work, the processor and the video card lower frequencies in order not to warm up even more. And, of course, here we tell how to clean the laptop, change the thermal polist, and in general how to disassemble it.

The reasons

If you notice that the fan is buzzing in a laptop, you should first figure out the factors that provoke the cause of this phenomenon:

• incorrectly selected settings that are responsible for the rotational speed of the fan;
• some parts of the device are heated greatly;
• the bearings of the cooler impeller were worn;
• on the cooler blades, a large cluster of dust or dirt was formed.

A fan buzzes in a laptop: what to do?

It is worth noting immediately to mark an important factor: if the buzz begins to appear when you run games or programs that overload the OS is normal. In this case, you can not worry. But if a small amount of the most is launched on the laptop standard softwareAt the same time, the device begins to buzz very much, then it is worth paying attention to this trouble. We offer the most optimal solutions.

If you know exactly why the fan is buzzing in a laptop, and it is overheating, then you need to find out whether you are working correctly. For example, if the laptop is all the time on a soft and uneven surface (carpet, sofa, plaid, etc.) - in this case, the noise indicates that the ventilation openings are blocked, and thus the gadget is actively fighting for its existence. In order to completely eliminate the phenomenon, it will be enough to keep the product on a solid and smooth surface all the time - so that air supplied to the radiator.

It is also worth noting the fact that special support for laptops become increasingly becoming more popular - they have a built-in cooler.

Another effective method - It is cleaning the product from dust clusters. Here you need to consider one point. If you are not sure that you can independently disassemble the device, while the laptop is under warranty - it is best to attribute it to the service center. There experienced professionals will fulfill all the work quickly and correctly, and you can avoid sad consequences.

If you are sure that the fan is very buzzing in a laptop because of the mud, while you know that you can independently carry out partial disassembly, then we recommend a series of actions:

1. Turn off the laptop, disconnect the adapter and pull out the battery.
2. We unscrew the screws that you will see on the rear panel. In some models of laptops, such screws can be hidden under special rubber legs - they should be carefully pushed with an acute subject to get to the screw.
3. Remove the lid - it is necessary to do it very carefully.
4. Using cotton wands, carefully consider the dirt and dust of the cooling system.
5. Small dust can be blown away. Or in advance to buy a special squeezed aircraft - similar products are sold in computer stores.
6. After all work is finished, you need to return the lid to the place, and spin the screws.
