Personal computer, laptop and even phoneconsist of many details. Some of them have the property of releasing heat in the process of work. In turn, the devices are equipped with various cooling systems, which must cool the components in order to avoid breakage from overheating. But if the processor overheats, what should I do? How to determine overheating and fix the situation? Here we describe the main causes of high CPU temperatures and how to eliminate them.
Symptoms of overheating are usually:
Check which elements are warming in the computer,you can use programs or via BIOS. In the second case, you can find out the temperature, and how much the processor overheats, if such a function is present in the BIOS firmware. The disadvantage of this method is the impossibility to check if there is overheating under load: when watching heavy HD video, during games or stress tests.
Find out how much the processor is overheatingcomputer, you can use third-party software, and monitor the status of your PC in any conditions. There are a lot of such software on the Internet, but there are several quite good programs: AIDA64 and Everest - two programs that can rightly be called twin sisters. The programs are created by one developer, have almost identical menus and have almost identical functions. They are paid, but have a trial period of free use in 30 days, when the program can be used without restrictions.
Each processor has its own temperature limit,The manufacturer installs, at which the computer turns off in case of overheating. Normally for the processor in standby mode, the temperature should be about 35-45 ° C, and under load (during the game or stress test) to 70 ° C. Exceeding these values can lead to irreparable consequences. In addition, when the processor overheats, the motherboard is heated, along with other elements that may be out of order.
Another good free, unpretentious program is the GPU-Z. The utility shows the temperature of the processor and other elements, as well as some other characteristics in real time.
Initially, why the processor on the computer overheats. The main and primary cause of overheating of the processor and other components of the computer or laptop is dust. It is everywhere and everywhere, gets into the computer case through the slots in the system unit, which serve to circulate air for cooling purposes. Fans together with air suck in dust, which then settles on all components, eventually growing into a pretty decent layer. Dust interferes with heat transfer and can even cause a short circuit. Therefore, the system unit of the personal computer and the laptop should be periodically cleaned.
It's quite easy to clean the PC from dust. The side cover of the system unit is fixed to the rear housing by two bolts (in most cases). It's easy to remove. Having opened the system, you can see how much it is heavily dusted, but do not flatter yourself, even a very small layer of dust can provoke overheating. Therefore, you should arm yourself with a simple set of tools, which includes a brush (there should be no metal elements on the brush to avoid a short circuit from static electricity), a compressed air bottle, napkins, a vacuum cleaner.
Before opening the system unit, you shouldremember, and it is better to draw a diagram, where and what to connect, as incorrect connection of plugs can damage the computer. Unplugging all the wires, before further action, you need to remove static electricity from the body: it is enough to simply wash your hands in running water. Static electricity when touching the parts or the computer case can cause a short circuit and, as a result, damage to the computer. After disconnecting the device, he needs to give 5 minutes to just stand up to leave the residual charge.
Now you can clean it. The main dust is concentrated around the rotating elements, on the coolers and in the radiators below them. Carefully vacuum the dust that has accumulated around the processor and in other easily accessible places. It is worth noting that for a vacuum cleaner you should use a nozzle with a narrowed nose (it is easier to collect dust). And it is also desirable that it be rubber. To remove dust by vacuuming it is necessary extremely accurately around small details on the motherboard, they can be accidentally broken off, and then the computer does not turn on at all. A can of compressed air should blow dust from hard-to-reach places, where it is difficult to get a brush and a vacuum cleaner.
Clearing the dust from the system unit, it is desirable immediatelychange thermal grease. If the computer is more than 2 years old and it has never been opened, the thermal paste, which ensures close contact between the processor and the cooling radiator, is likely to have dried up and does not provide proper cooling. Because of this, the processor overheats and the computer turns off.
It is important not to overdo it, becausethe thermal conductivity of even the most expensive thermal paste is much worse than the heat conductivity of the cheapest radiator, so a fairly solid layer of thermal paste will play a cruel joke and cause the processor to heat even more due to poor heat transfer. Thermo-pastes need absolutely a drop, literally from a match head. It should be evenly applied and smeared on the processor platform (you can use an old plastic card).
Further tightly press the radiator, setting it inthe starting position, and snap the fasteners. The radiator should not be loose or loose. After cleaning from dust and changing the thermal paste, all peripheral devices, as well as all I / O chips, should be connected. After that, you can turn on the computer for verification.
In the computer, the processor itself can not be heated yet,but a sensor. It looks like it's overheating the processor. If the cleaning is done, the thermal paste is replaced, and the figures are still too high, then you can install additional cooling in the system unit to blow the motherboard. Or install a more powerful cooler on the processor (the old one can not cope with the cooling task).
When the processor on the laptop overheatsdue to a strong dustiness, here everything is somewhat more complicated. And if you yourself have never dismantled the laptop for cleaning, then it is worth to give it to the service center. Because the bolts on the back cover of the laptop have different lengths, respectively, unscrewing them, you should simultaneously draw a diagram. Inside the laptop, everything is much smaller and more compactly located than in the system unit and there is a chance to damage something. The cooling system also differs in different notebook models.
Tip: clean your laptop or computer at least once every two years. With the same frequency, you need to change the thermal paste. If there are animals in the house, then cleaning should be done at least once a year, and preferably every six months, since along with the dust in the system block, the villi of the animal's fur also fall.
In summer, it is usually hot, and sometimes because ofexternal factors overheat the processor on the laptop. What to do in this case, how to cool it? The cooling system draws in air from outside, and if the room is already hot in the hot summer day, the hot air will not help much. To cool the laptop you can use external supports with cooling elements. This will reduce the temperature of the motherboard and processor, avoiding the harmful effects of high temperatures on them.
Overheating of the processor can viralinfection. It is worthwhile to scan for viruses and it is desirable to do this either by cloud antivirus, or to install another, after removing the stationary antivirus. Malicious code in the computer could already infect the antivirus program or disguise itself, because of what your antivirus will not see the infection.
You need to check if the svchost system is loading.exe is an auxiliary process for services loaded from dynamic libraries. But sometimes under the guise of a system process, a virus or malicious code can be hidden that continuously starts any system process, loading the CPU, resulting in overheating.
Because of software conflict, the processor overheats, what should I do?
Often one can observe how overheatingprocessor on the phone. This is most often associated with a large number of simultaneously running processes, applications, during a long conversation or on charging. Overheating of the phone during charging most often happens because of a poor-quality charger or battery that has already worked out its time or damaged, and if the connector's pins are dirty. To cool the phone, you need to download applications that monitor CPU CPU temperature and alert you in a timely manner of the critical temperature.
Problems with overheating, though not always obvious,and often difficult to determine, are solved in most cases very quickly, except for the breakdown of the cooling system, where replacement of components or the whole system is required. Now you know why the processor overheats, and how to fix it. A healthy PC, easy work and a pleasant pastime for your favorite computer!
