Why did the laptop become very noisy? What to do if overheating is detected? Reducing hard drive clicking noise

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 “general cleaning,” which includes not only removing dirt, 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. Do not 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. Sewing machine or gun oil is also suitable. 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

Many laptop users, especially those who purchased a laptop for the first time, ask “Why is my laptop humming?” Of course, it would be more correct to ask: “Why is the laptop making noise?”, but this does not change the essence of the question.
So, it is worth considering two cases:
1 case. The laptop hums (makes noise) immediately after purchase, i.e. We are talking about a new laptop.
So, if a new laptop hums (makes noise) during operation, then, as a rule, there is nothing to worry about. The fact is that, as in a regular (desktop computer), the cooling system of the laptop processor includes a fan, which makes noise during operation.

Laptop processor cooling fan

The fan does not work constantly, but turns on only if the laptop processor gets very hot. When the fan turns on, the noise appears.
Here a second question may arise: “My neighbor (acquaintance, brother, matchmaker) doesn’t make noise, but why does mine make noise?” If your friend has exactly the same laptop model, then it’s worth thinking about. But as a rule, it turns out that we are talking about a different model and the laptop is actually practically silent during operation.
What is the reason for this difference? The reason is simple - laptops have different configurations, i.e. simply put, different internals. We are talking about the processor, hard drive, RAM, etc.

The components of your computer heat up more than the components of your friend’s laptop; for this reason, your laptop has a more efficient fan (cooler) with higher speeds or larger blades. Naturally, such a fan will make more noise.

Let me give you one example from practice. For a very long time I had the opportunity to hold in my hands a laptop made on the basis of the Celeron-700 processor. When it was running, even under load, I noticed that the fan made virtually no noise.

Not long ago, I was holding an eMachines-430E laptop based on the Semprom-100 processor. The fan also did not make much noise when operating. As for my home laptop Lenovo B550 based on the Intel Pentium T4400 processor, the fan is quite noisy during operation. Why? Yes, it’s just that the processor of my laptop is “more powerful” than the processor of the eMachines-430E laptop and generates more heat during operation.

Case 2. Previously, the laptop did not hum (did not make noise), but now the noise is getting stronger. Actually there are two visible reasons:

A certain amount of dust has accumulated in the laptop case and it’s time to clean it.
The cooler bearing is worn out and the cooler needs to be replaced. In such cases, some comrades suggest lubricating the fan without changing it. I am against such experiments and recommend replacing the fan with a new one. Here you should immediately note that different fans have different noise levels during operation and you should choose a cooler with minimal noise.

Typically, portable computers—notebooks, laptops, netbooks, and ultrabooks—are relatively quiet. Special components are developed for them that have lower heat transfer and a quiet cooling system is installed. But sooner or later, any owner of such a device may encounter the fact that the computer begins to make sounds - buzzing and buzzing. You shouldn’t be immediately scared by this and run headlong into a service center or call a computer technician. First you should try to figure it out yourself - why is my laptop humming??

The situations that arise can be divided into two groups:

The new laptop suddenly buzzed

The first reaction of an ordinary user is “broke”! Not really. It’s just that the laptop gets very hot and therefore the cooler (fan) hums, trying to cool the processor. There are several ways to deal with this.

1. Setting up the power supply scheme.

Powerful and fast laptops, at maximum operating parameters, usually get very hot. However, in most cases, maximum performance is not needed (of course, if you are not a fan of games). We do the following: press the key combination Win+R. The Run window will open:

Enter the command powercfg.cpl and click on the OK button. The Windows operating system power settings window will open:

If your power plan is set to “High Performance”, change it to “Balanced”. After that, close the window and reboot.

2. Using a laptop stand:

Now in any more or less large store that sells computers and components, you can buy a special cooling pad for a laptop:

It is usually a special platform with built-in fans that drive cool air to the bottom of the laptop, which heats up the most. This is a very convenient thing, which also allows you to position the laptop more comfortably and prevents anything from blocking the cooling system holes on its case.

Old laptop hums

If your old comrade suddenly started making noise with his cooler, then try to remember when you cleaned it. Would you like to see what its cooling system looks like after 2-3 years of active use:

Dust and hair clog the radiator to the point where airflow can barely pass through it. The cooler begins to blow hot air. It is clear that this is not enough and the system begins to increase the fan speed. That's why the laptop starts humming because it simply can't handle the heat. The solution is simple - cleaning and purging.

If you yourself can unscrew a few screws on the bottom of the case and get to the fan, then clean it carefully, first with a dry and then a damp cotton swab:

Blowing out the radiator is also not difficult - you either need to buy a can of compressed air at a computer store, or use some weak car compressor. As an option, you can blow it out with an old Soviet vacuum cleaner that can operate in blowing mode. The main thing is not to try to clean with a vacuum cleaner - this can end sadly.

And finally, a piece of advice - try to place the laptop on a flat, hard surface so as not to block the ventilation holes under any circumstances. It is also advisable to place it in a normally ventilated place. Then it will delight you with normal and quiet operation for a long time.

Many laptop users experience annoying noise coming from their devices.

It can be especially noticeable in the summer, when the heat causes components to overheat and cooling systems to operate at increased speeds.

So people have to go to the Internet and look for an answer to the question: the laptop is making a lot of noise, what should I do?

But before we begin to consider ways to eliminate the problem, we first need to understand the causes that provoke it.

Causes of noise in a laptop

Overheat.

The most common phenomenon in laptops.

The form factor of such devices simply does not allow for truly effective cooling to be installed there, so the temperature often rises to a critical level, sensors inside read all this and increase the rotation speed of the coolers.

Accordingly, an unpleasant hum begins to come from the case. Overheating is also caused by dust accumulating inside, which interferes with heat removal and normal air circulation.

Damage to the cooling system.

The most common occurrence is banal wear of bearings, leading to radial runout and, as a consequence, contact between parts that should not be in contact in any way.

A slight tilt, and now something somewhere is rubbing, grinding and making other unpleasant sounds.

Incorrect software settings.

Illiterate users, having tinkered with Bios settings and special programs in an attempt to overclock the power of their device, often then begin to sincerely wonder why the fan in the laptop is noisy.

And the reason is simple - the hardware is not designed to work with such installations, it heats up and forces the coolers to spin at maximum speed.

Malicious code.

Various viruses are often able to get into system processes and use hardware resources for their own purposes (the same miners who extract cryptocurrency for their owners).

So it happens that users are surprised - they seem to be sitting and just typing in Word, but the laptop is making a loud noise, as if they are playing the latest action game on Ultra settings.

Diagnosis of problems

Determining the causes of noise is not difficult, especially when it comes to overheating.

The hum from the case is not the only symptom - freezing and braking are observed, the device can spontaneously reboot if it is used for some time in a resource-intensive application or computer game.

This can happen due to the presence of dust and dirt inside the cooling system, dried thermal paste, or difficult air exchange. To verify this, just climb inside the case.

It is much more difficult to determine the problem if the cause is software in nature.

Install a reliable statistics collection program on your system, such as Everest. It will clearly show at what specific settings the laptop hardware operates (frequencies, voltage).

If you changed something before discovering the noise problem, it is better to return all parameters to standard/optimal values.

Quick cleaning of a laptop cooler fan

So, having gained an idea of the main reasons that cause unpleasant and intrusive noises, you should begin to eliminate them.

Let's start with the most obvious - if the cooler on your laptop starts making noise, you should inspect and clean it.

Anyone can handle this, but do not forget that any penetration into the case will result in the loss of the manufacturer's warranty. So, the sequence of actions is as follows:

The quick cleaning procedure described above does not always help - often more serious measures are required, requiring complete disassembly, replacement of thermal pads, thermal paste, etc.

All this is written in detail in the article “Cleaning a laptop from dust.” We recommend that you familiarize yourself with it.

Cooler speed adjustment programs

If the laptop cooler hums even in a calm state, but there are no obvious signs of overheating, this may indicate that the blade speed is too high.

Fortunately, it can be easily reduced using one of the programs described below:

You can also try to adjust the cooler speed through the BIOS.

To do this, when turning on the laptop, press the Del key (some manufacturers use other keys), and then find the Power or H/W Monitor Configuration section in the window that opens.

They should contain an item responsible for the speed of the fans.

Set the percentage value you need, then save the changes and start the system. But do not overdo it - if the speed is minimal, this can lead to overheating and component failure.

Other methods to prevent fan noise

In addition to cleaning and monitoring the rotation speed of coolers with special software, there are several other tools that can help owners of noisy laptops in certain situations.

Cooling Pads

Laptop stands with a built-in cooling system come to the rescue if the coolers built into the device cannot cope with the tasks assigned to them.

and they have one or more additional fans installed that blow air over the laptop body and thereby lower its temperature. The quality of airflow greatly depends on the manufacturer and model of the gadget.

If you buy a cheap budget stand, you are unlikely to get rid of overheating. In addition, it may well aggravate the situation by further increasing the noise level.

DeepCool performed well in the budget segment, and CoolerMaster performed well in the expensive segment.

Laptop BIOS update

When the fan in the laptop is very noisy even when turned on, this may be a consequence of incorrect settings in the BIOS.

That is, the developers themselves made mistakes that did not allow the system to normally read readings from temperature sensors and control the rotation speed of coolers.

Some BIOS versions do not even provide users with manual configuration options. Therefore, it is recommended to go to the manufacturers’ official page, find the latest BIOS version for your laptop model and install it following the instructions posted there.

Don't forget to remove the disc from the drive

It seems like a small thing, but it can greatly affect the noise level. A working CD/DVD drive creates vibration, which is transmitted to the rest of the device.

Such an impact will obviously not benefit them, so it is better not to keep disks in the drive, but to use more modern drives (flash drives, external HDD/SSD). They not only do not emit noise, but are also more compact and resistant to damage.

That's all. If after reading the material you still have any questions or would like to supplement it with useful information, do not hesitate to write in the comments!

In this article we will talk about what to do if the laptop gets hot, makes noise, and periodically turns off.

In recent years, ordinary users are increasingly abandoning the use of desktop computers, opting for laptops. This is due to the fact that a 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 the 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 to do if the laptop gets hot?

The presence of various kinds of distortion on the display of a working laptop, excessive heating of the lower part of its case, as well as extraneous noise are an alarming sign and indicate the presence of an internal malfunction. Such problems must be resolved as soon as possible, otherwise there is a high probability of overheating of the processor, graphics adapter and other parts, which can lead to their complete inoperability.

The laptop can overheat for two reasons:

Your laptop is clogged with a layer of dust, which also leads to loud noise and heating of the entire laptop system.
There is no thermal paste on the CPU, or it has simply dried out and dried out.

But we still note that both cases require disassembling the device.

Thermal paste is dry or missing on the processor and adapters

Thermal paste located on the video card and CPU coolers. It must be replaced with a new paste using a plastic card. If you have not performed such actions before, 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

Dust formation is usually associated with active operation of coolers. Very often it accumulates on the cooling grilles and impedes the passage of air. Therefore, it is advisable to remove dust regularly.

The hard drive has become unusable

Continuous use of a laptop in some cases leads to clicks that are not typical for its operation. These are symptoms of a hard drive failure or a malfunction of the cooling radiators.

In most cases, a hard drive failure requires its replacement, since the operating life of such devices is limited. Shocks and mechanical damage also negatively affect the condition of the disks and can sometimes even lead to their complete inoperability.

Fans (cooler) are clogged with dust and debris

If the source of extraneous noise is the cooler, you need to check whether any debris or foreign objects have gotten inside the case, and whether the grease on the bearings has dried out. Accordingly, you need to lubricate the bearings with a specially designed compound and carefully clean the housing.

What should you do if you detect extraneous noise on your laptop?

If the slightest sign of a device malfunction appears, promptly eliminate its cause.
If you are unable to clean the device yourself, contact a service center for help.
Monitor the status of the central processor, video card and hard drives. Ensure they are repaired in a timely manner in cases of frequent heating and other problems.

Well, this is where we will probably finish our article today.
