The processor on the computer is very hot. What to do? What to do if the computer is warming up

Often, users are faced with a problem when the processor on the computer is warming up... What to do in such a situation? As a rule, the most reliable option- this will ask for help from the master. In case the master could not come or you simply want to save money on repairs, then this article is for you.

The processor on the computer is warming up. What to do?

Opening the lid system unit and find the processor cooling system there. As a rule, the first thing that catches your eye is a radiator with a fan in the most conspicuous place.

Dust cleaning

We inspect the radiator for dust clogging.

If found, carefully remove the dust in any way that comes to your head. It is advisable to remove the fan and clean the radiator with a brush to perfect condition, but this is not always easy to do. When the fan is not fastened with screws, but is fixed in a different way, then in inept hands, removing the fan becomes a whole problem. In this case, you can remove large pieces of dust with a toothpick without removing the fan.

After you remove the dust from the radiator, you will need to turn on the computer and run the test, as described in the article - Check the temperature of the processor and video card.

In most cases, removing dust from the processor heatsink will solve the overheating problem, but not always. If, after cleaning, the processor still shows an increased temperature in the load, then proceed to the next step - replacing the thermal paste.

Replacing thermal paste

To change the thermal grease, you need to remove the heatsink, remove the old thermal grease and then apply a new one. To do this, you need to get thermal paste in advance. So let's get started.

There are two common types of motherboard heat sink attachment: for AMD processors and Intel processors. AMD uses a lever mount and Intel uses a 4-clip mount.

Sometimes you can find a radiator that is fastened with screws. Everything is simple here, unscrew the screws, remove the radiator.

Remove the radiator from motherboard... Using a dry cloth or napkins, remove the old thermal grease from the processor and heatsink. Then thin layer you need to apply new thermal grease, and then put the radiator back on. Remember to connect the fan power to the motherboard.

Ready! We turn on the computer again and run the test to check the temperature in the load. If this time the temperature also exceeds allowable limit, you will have to seek help from the master. Your processor may be damaged.

Sometimes it happens that after replacing the thermal paste, or for no apparent reason, the processor starts to get very hot. This can lead to the most unpleasant consequences, the personal computer starts to work slowly. This is especially noticeable when performing any operations that require a large amount of resources.

At the first suspicion of overheating, it is necessary to install a special diagnostic program that receives temperature data directly from the sensors. It is advisable to monitor the CPU and if during its operation the temperature goes beyond the permissible limits, it is imperative to take action.

Overheating reasons

Determining why the CPU is overheating is usually not difficult. Since there is a fairly limited list of the main reasons for this phenomenon.

Most often, the occurrence of heating is associated with the presence of some important factors:

dustiness of the cooler, radiator;
thermal paste that has lost its heat-conducting qualities;
there is no normal ventilation;
the capacitors on the board are out of order;
the CPU was overclocked.

Dust

One of the most frequent problems, which is associated with strong heating of any part of the PC, not only the CPU - this is ordinary room dust. A working computer accumulates a charge around itself; the case is a kind of capacitor. Static electricity is generated, and it attracts a large amount of dust, as well as ordinary hair. All this is hammered into the radiator grill.

Over time, the amount of dust becomes so large that it interferes with normal heat dissipation. As a result - a significant increase in the temperature of the CPU. In some advanced cases, it can warm up to 100 degrees. Dealing with such a nuisance is quite simple.

Incorrectly applied or dried thermal paste

The reason for the unsatisfactory heat dissipation can be incorrectly applied or completely dried thermal paste. This compound is a substance located between the outside of the CPU case and a special heat sink. It has a very high thermal conductivity. That is why when it loses its properties, the CPU crystal begins to warm up strongly.

It is quite simple to eliminate such a phenomenon, but it is best not to allow its occurrence at all. This will allow you to avoid various troubles - an arbitrary shutdown of the computer, as well as restarting or just a banal breakdown due to overheating.

Lack of good ventilation

Almost all cases of stationary PCs or laptops are equipped with special grilles through which it is discharged naturally or forcibly. hot air... If for some reason this does not happen, then some problems may arise due to overheating.

The reasons for this phenomenon may be:

stopping the cooler performing forced ventilation;
the ventilation grilles and openings are covered (the PC case is poorly located or simply clogged with dust).

Problems in the elements (capacitors) on the board

Sometimes it is quite simple to figure out what is the cause of overheating. It is only necessary to carefully examine the electronic components located on the motherboard. Often raising temperature regime caused by the failure of capacitors. Determining their malfunction is quite simple.

The elements in question, located on the motherboard, look like bars on two thin legs. There is a cross at the end end. If swelling is present, then most likely the capacitor is about to fail or has already broken. In this state, its capacity drops, and it begins to heat up. How to check if it is warming up: just gently touch it with your finger.

Overclocking the processor

Very often, many users practice overclocking their PC. The essence of this operation is to increase clock frequency CPU. This can be done both through BIOS and using a specialized software. Side effect a similar action is to increase the temperature of the processor. Sometimes it greatly exceeds the permissible limits.

Temperature check

If you find any signs of PC overheating, you need to install a dedicated temperature checker application.

The most popular utilities of this type today are the following:

Core Temp;
Speed Fan;
Real Temp;
Hmonitor.

It is very important to remember that these utilities do not always display reliable information.

In addition to them, to obtain the necessary data, you can use:

gadgets for Windows;
BIOS.

Operating room Windows system 7 is equipped with special widgets, which are usually located on the desktop. One of them is a sensor that displays working temperature CPU as well as its load. In most cases, the information obtained in this way is reliable.

Most accurately, only BIOS will be able to display the actual temperature. You just need to go to the appropriate section. In addition, there are usually similar data on the motherboard nearby. But remember - the sensor can also lie sometimes. Such devices tend to fail.

What to do if the processor is hot

To make the PC operating mode normal, to avoid even the possibility of overheating, it is necessary to take a number of appropriate measures.

They will save the user from the occurrence of various glitches, arbitrary restarts and shutdowns:

dust removal;
installation of additional cooling;
replacement of thermal paste;
replacement of electronic components on the motherboard.

Dust cleaning

Stationary computer installed in ordinary room on the floor or even on a table, collects a very large amount of dust.

To carry out the cleaning process, you will need the following items:

Using special Phillips screwdrivers, disassemble the PC case and inspect the CPU cooling heatsink. Most often it is located under the cooler, which is also bolted.

The cleaning process is carried out as follows:

Best used for cleaning household vacuum cleaner, not USB. Since the latter, often, has insufficient power, and it takes a long time to clean it. Which is not very convenient.

We put additional cooling

Overheating problem can be solved by installing additional cooling. Today, in most computer stores, you can easily buy the necessary devices for this without any difficulty. The installation process usually does not cause problems.

Most modern enclosures have slots specifically for mounting. additional coolers... If there is insufficient cooling, you can simply install another fan. Most often special air vent for this it is present in the end part of the case, under the power supply. For fastening, you only need 2-4 self-tapping screws or screws, a screwdriver.

There is one important point- it is necessary to make sure that the PSU cooler and the additional one work in antiphase. That is, one of the fans must draw in air and throw the other out. Such a system most effectively removes heat from the system unit and directly from the processor itself.

Changing the thermal paste

With long-term intensive use of a PC, in most cases, thermal paste loses its properties and needs to be replaced.

This process is carried out as follows:

There is a fairly large selection of various thermal pastes in stores. The compromise option price / quality is AlSil-3 - composition domestic production... You can also use branded pastes.

Replacing elements

If swollen capacitors are found on the motherboard, then you can try to rewire them.

This will require:

Replacing elements is done as follows:

use a hair dryer to warm up the element;
the capacitor is removed with tweezers;
having melted the solder again, you should install a new capacitor - while observing the polarity.

It is imperative to constantly monitor the temperature of the central processor. And take appropriate action when a malfunction occurs. Otherwise, there is a high probability of complete failure of the CPU.

Often computer technology fails when the processor overheats. We decided to clarify the situation a little and tell you how problems with overheating are solved.

Why is the processor overheating?

1.CPU cooler clogged with dust

The only way to get rid of the dust is with a brush and vacuum cleaner to remove it from the radiator. The computer is much easier, it is easy to clean. If you have a laptop, you will have to completely disassemble it for cleaning. For an example of how to disassemble a laptop, see.

2.Used processor without thermal paste or thermal paste is dry

In this case, the temperature of your processor will be higher than normal. In extreme heat, under heavy loads, the processor may overheat. Previously, we saw the difference in CPU temperature with and without thermal paste. We recommend that you definitely use thermal paste.

3.The thermal paste between the die and the processor cover is dry

If you have a clean heatsink, the cooler is working, the best thermal grease is used, and the processor is overheating. Most likely, the thermal paste on the processor crystal has become unusable.

In order to disassemble the processor, carefully, using a blade or a utility knife, cut the layer between the lid and the processor. Then wipe off the dried thermal paste from the crystal and lid and replace with a new one.

4. The CPU cooler does not work.

The cooler needs to be cleaned, lubricated or replaced with a new one.

7.On the board, the heatsink to the processor is broken

Try to move the radiator with your hand. If it dangles from one side, check the reliability of the fastening. It may have broken or snapped off. Because of this, the heatsink does not completely adhere to the processor and overheating occurs. A broken mount needs to be replaced with a new one, it makes no sense to glue it.

conclusions

The state of the computer or laptop must be monitored. Dust must be cleaned at least once a year. If you do not know how to do it yourself, contact the specialists.

Overheating is most dangerous for a laptop, since there is one cooling system for the processor and video. In case of severe overheating, the video chip can be damaged and then expensive repairs will be required to restore operability.

Overheating of a computer or its individual components can cause various problems and system malfunctions: the OS periodically slows down, freezes, strange graphic artifacts are displayed on the screen, unplanned reboots occur, which may be accompanied by a blue "screen of death".

In most cases, the symptoms listed above indicate overheating of the computer. To solve this problem, the user first needs to understand what is causing the overheating.

Causes of computer overheating and their elimination

Gone are the days when overheating of one or another component led, in most cases, to its fire. However, overheating is still one of the main reasons for reducing the service life and failure of the system unit components. There may be several reasons, here are some.

Contamination of the system unit.

Contamination of the system unit is perhaps the most common cause of overheating of components. Cooling systems are a real magnet for dust, which settles on them in an impressive layer and interferes with the normal heat dissipation.

This is especially true for budget cases, which are almost completely devoid of dust protection in the form of special filters.

Not all users are in a hurry to disassemble their system unit, wipe it from dust and clean the cooling system. However, it is simply necessary to do this, because such a simple procedure will significantly reduce the risk of failure of any component as a result of overheating.

The cleaning procedure is pretty simple

Having opened the lid of the system unit, remove the following components - a video card, a processor with a cooler and case fans, disconnect the wires.
Remove the dust from the "iron" remaining in the block. A small brush is best suited for this purpose, as it can be used to easily remove accumulated debris from corners.
The easiest way to clean radiators is with a compressed air cylinder (you can buy these at almost any computer store).
After making sure that all surfaces are free of dust, you can return all components to their place.

This procedure is best done on fresh air or, for example, on the balcony.

Attention! Using a conventional vacuum cleaner to clean the body is undesirable. In any case, in the blowing mode. Computer components are quite fragile. To apply mechanical damage very simple, which is fraught with additional costs.

Drying or improper application of thermal paste.

Drying of thermal paste leads to the fact that the processor starts to heat up more often, its clock frequency automatically decreases, which means that performance decreases. An excess of pasta is not desirable. If you smear the surfaces of the heatsink or processor very generously, then you can achieve the opposite effect - the heat transfer will decrease.

Correct application of thermal paste means spreading it evenly with a thin layer. You can do this with your finger (as shown in the picture), but a plastic card (for example, a business card) is best suited for the implementation of the task.

When the paste is applied, press it against the processor, and remove any residues from the sides. Everything, nothing complicated. Which thermal paste is better to choose and how to change it is described in one of the previous articles. I recommend that you familiarize yourself with it at.

Insufficient capacity of the cooling systems.

A typical situation - a person buys a new computer in the fall or winter, uses it for a while, but then, when the hot season comes, suddenly problems with overheating begin. Processors with standard (included in the basic kit) cooling most often overheat.

A successful (efficient) boxed cooler is a rare thing. Now on the market there are quite a few high-quality and inexpensive (600-800 rubles) solutions from DeepCool, Zalman and other manufacturers.

If you can't upgrade right away, take simple steps to reduce overheating. After all, he is able to harm the components, which will lead to even greater expenses.

1) Install on your computer SpeedFan program, which allows you to monitor the temperature in the system unit, as well as control the fan speed. If the coolers are only running at half their capacity, increase the speed.
2) Work at the computer when open lid system unit - this will improve the flow of cold air and the return of hot air.
3) Move the system unit away from possible heat sources (battery, sun).
3) Reduce settings in resource-intensive applications and games. All these shadows High Quality, particles and detailed models put a lot of stress on the iron. 100% loaded graphics cards and processors generate much more heat.

The quality of cooling is influenced not only by the cooling system itself, but also by the correct location in the system unit. Make sure that the coolers of the system unit are installed correctly. As a rule, 1-2 fans are installed on the front wall of the case for blowing a cold stream, on the back and top cover - for blowing out warm air.

Overclocking components and incorrect BIOS settings.

Very often, the victims of overheating are those who like to use the "untapped potential" of their iron. They go to Overclockers or other similar forums, read the reports written by the professionals in the business, and then try to repeat. Usually, it all comes down to an uncontrolled increase in the processor multiplier. They are unlikely to feel a significant increase in performance, but overheating is easy.

Fortunately, modern processors and video cards are equipped with overheating protection mechanisms, so it will be quite difficult to burn them. When the temperature reaches a critical level, the computer will automatically restart.

To get it back in working order, you will have to roll back the changes. There is a special button for this in the BIOS that allows you to return to the standard settings.

Errors when choosing components.

Deciding to collect your own system, remember about important condition- it must be balanced. You can use special online collectors (PC Configurator) and counting calculators required power power supply unit.

As an example:
- http://www.regard.ru/cfg
- https://ru.msi.com/calculator

No need to skimp on important parts such as the motherboard and good block nutrition. A frankly budget motherboard and a weak power supply unit may well lead to regular overheating of components with their subsequent failure.

Any specialist knows how big the difference can be between the declared power of the power supply unit and its real rating. 500W of an unknown Chinese company is by no means equal to 500W of a trusted manufacturer. Otherwise, there would be no double price spread.

Conclusion

Overheating of the computer and its components is quite serious problem which in best case will remind of itself at the moment, slow down the system, at worst - will disable expensive hardware.

The best way to combat overheating is to prevent it. If you assemble a competent and balanced system, clean the system unit and thermal paste in a timely manner, do not bump into experiments with overclocking, then you can protect your PC from brakes, reboots for a long time, blue screens and other troubles.
