• Causes of overheating of the computer processor. Why does the processor on my computer get very hot?

    CPU is the brain of your computer, processing millions of bits of information every second. It is for this reason that the processor generates a lot of heat: it’s not for nothing that people use the expression “brains are melting.” To prevent the processor from burning out, it is equipped with two protection options:

    1. radiator, on which the cooler is installed;
    2. temperature sensor-relay, which turns off the computer when it reaches critical temperature processor.

    But what to do if the processor begins to heat up constantly, even when the system is idle? Well, let's watch. So!

    The advice given on online forums on the issue of processor overheating is not original. Basically these are:

    1. put additional cooling;
    2. change thermal paste, ;
    3. clean the system unit;
    4. buy a new computer.

    You know, I like the last option better. But since I don’t have extra money, I have to solve problems with my own hands (with my brains in tandem).

    If your processor is constantly overheating, and no measures help (in the above list under numbers 1, 2, 3), then most likely you are looking for a solution in the wrong direction!

    Cleaning the socket

    Before performing the steps below, be sure to Check CPU % in task manager(The task manager in Windows OS is launched by simultaneously pressing the CTRL+ALT+DELETE keys). If your processor operates at less than 50% - 70% (it is advisable to unload it completely) and at the same time overheats, then you should try the algorithm described below.

    Attention! I would like to note right away that the malfunction is quite rare, but if cleaning the coolers (provided they are working), the case, replacing the thermal paste did not give anything, only then you should try this method.

    Here is an algorithm for solving the problem, which helped not only me, but also dozens of users who had the same problem.

    1. Turn off the computer. We put the computer on its side. Removing the wall system unit. Do you see the processor heatsink and cooler? Great, then your vision is fine.
    2. Then very carefully disconnect power to cooler. Don't know how? It's simple. Two wires with a plug at the ends go from the cooler to the motherboard. This plug must be very gently pulled out of its socket on the motherboard.
    3. Next - remove the cooler and radiator. After you have removed the heatsink, you see the processor itself, on which the remains of thermal paste are visible (or maybe not visible). The processor is installed in a special socket called a “socket”.
    4. Remove the processor from the socket- a task that is both simple and difficult at the same time. The difficulty is that without knowing exactly how the socket comes off, the “teapot” risks breaking the latches of this socket, thereby breaking the computer. (From the author: the main purpose of the socket is close contact between motherboard and processor. And any violation of this contact inevitably leads to loss of system functionality). Typically, each socket is equipped with a special locking mechanism: these plastic “claws”. These “legs” must be very carefully lifted up: the door will open. That's it: now the processor can be removed. And one more precaution: the processor has many “legs” on the back side. These “legs” cannot be bent!
    5. After removing the processor, look inside socket: There's dust there! This dust is the source of high processor temperatures. Take a brush and carefully removing dust deposits.
    6. Then carefully insert the processor into place and press it with the mechanism.
    7. Apply fresh thermal paste on the processor and on the bottom of the heatsink.
    8. Installing a heatsink on the processor, and on the radiator we install cooler.
    9. Turn on the cooler plug into the socket on the motherboard: otherwise it won’t work!
    10. Starting the system. That's it: there should be no overheating!

    It is natural that this method- this is not a panacea for overheating, because the reasons may lie in another direction. For example, if you have weak computer, and you installed powerful antivirus, such as “Comodo”: it consumes a colossal system resource and therefore the processor can also burn! However, the above method of solving the problem helped not only me, but also dozens of other sufferers: perhaps this is your case?

    How much information did I process with something like this? search query, probably a thousand pages.

    CPU AMD Athlon 64 X2

    Motherboard: MSI K9N Ultra (MS-7250 v2), socket AM2, DDR2 memory.

    With the onset of summer, it began to warm up and at 70 degrees the protection was triggered and the computer turned off, first at heavy games, in the end, even with Internet surfing. No matter how many times I ask why this happens, there are basically three answers:

    1) install a more powerful cooler

    2) vacuumed

    3) replace the thermal paste, and apply a layer that is neither too thin nor too thick

    To my objections that the computer was several years old and this cooler was always enough, there was practically no answer, there was not a speck of dust inside, I blamed the thermal paste 10 times. They advised me to buy a serious cooler, for example Ice Hammer, it really impresses, prices start from 1000 rubles.

    There were also these versions:

    4) overheats due to virus activity (I tried to scan with an antivirus, but during the scan the processor got hot and the computer turned off);

    5) the temperature sensor on the processor has failed, the only solution is to improve cooling or replace the processor;

    6) the motherboard has bent, which is why the cooler radiator does not press tightly against the processor and receives heat;

    7) the processor starts to heat up if its pins-contacts bend (yes, it happened);

    8) “the south bridge can’t cope” (I touched the south bridge and went nuts - it’s hot, it burns my finger. I screwed a fan from an old processor cooler and a radiator to it south bridge became cold, but the computer still turned off due to processor overheating);

    9) reading a forum about some kind of motherboard and overheating AMD processor on it, I discovered this solution to overheating - put cardboard under the processor along the edges, so it will rise and press closer to the radiator, i.e. over time, the motherboard could sag under the processor and the cooler would not press tightly (I did this on my computer, it did not help);

    10) I read the overlocker forum on MSI boards, it turns out my motherboard may have problems with copying large files and when connecting the hard drives to the IDE connector, the computer turns off (I must say I didn’t notice this on my computer, but I followed the recommendations to fix the bug - I changed the BIOS settings and wanted to resolder the C565 condenser, but couldn’t find it);

    11) a gap has formed between the processor cover and the crystal, you need to remove the processor cover and put the cooler radiator directly on the crystal (tin, of course)

    I bought a special POST card for diagnosing motherboards, the POST card showed no errors.

    After many other ways to fix the problem, I decided to open the processor, especially since I had doubts about its condition and I was not afraid of breaking it completely. The processor cover is glued very tightly with rubber sealant; when opening it, two elements under the cover were crushed by me... I had to look for a new used processor (such processors are no longer produced)...

    I found out that you can insert an AM3 socket processor (next generation) into the AM2 socket and in most cases it should work, although not at full capacity, I was of course happy because this is an opportunity to do a step-by-step upgrade, but as it turned out, MSI did not write a BIOS with AM3 support and all its clients fail (I don’t want MSI anymore, why can other boards do this, but MSI board No?).

    Well, the purchase of the A3 processor was a bummer, I had to buy a used AM2, and bought a more powerful one.

    I installed it and was sad - it also gets hot and the computer turns off, took it out....

    It's all in vain, mate. the board probably needs to be changed, or maybe buy it first powerful cooler? It’s hard to believe that it will help because... The processor is heating up like an iron... I’ll take it to a service center for diagnostics and see what they say.

    And then I remembered about programs for optimizing the operation of the cores of the dual-core Athlone processor, supposedly they improve its performance. I found 2 similar programs on the Internet: “AMDcpuv1.3.2.6.exe” and “ AMD Dual- Core Optimizer v 9.0.333.0.exe."

    I installed both at once and a MIRACLE happened!!! The processor temperature began to drop, dropping by 20 degrees at once. NO REPLACEMENT OF COOLER!!! Now the temperature is 30-40 degrees, during games - 53!!!

    This is how it happens, software, not hard, helped eliminate the overheating problem.

    PS: the processor cover turned out to be a good-quality copper plate, it was pressed well to the crystal, there was thermal paste. I don’t see the point in opening the processor and I don’t recommend doing it. Now you can make a keychain from the lid.

    This is what the processor looks like disassembled:

    It doesn’t matter how, but suddenly you find out that the processor on your computer is overheating. Maybe you burned yourself on it, maybe you looked at it through a monitoring program, or maybe smoke was already pouring out of the computer

    What are there reasons for processor overheating– that’s what we’ll talk about today.

    What are the dangers of processor overheating?

    Many people ask this question, and rightly so. After all, processor overheating is a serious thing, which, in extreme cases, can lead to computer failure. But that’s just me, I tell you right away about the terrible things so that you don’t relax

    All modern boards are equipped with all kinds of sensors that tirelessly monitor the state of the system, including the operation of the processor. And when the temperature approaches a critical level, the so-called mode is activated on the processor throttling(not to be confused with trolling), in which the processor begins to skip clock cycles. This significantly reduces the processor's power, and at the same time the heating rate.

    So first of all, CPU overheating affects performance computer, and secondly, can lead to extreme unstable work computer.

    Reasons for CPU overheating

    Now let's talk about the main thing - what actually causes the processor to overheat. If your processor is suffering from overheating, check all the reasons listed below in order - they are listed from the simplest to the least obvious:

    1. Dust in the cooling radiator

    Dust inside the computer, and especially a radiator clogged with dust, is the main reason for overheating of all processors. Dust reduces cooling efficiency and causes the processor to overheat.

    The solution is quite simple - thoroughly vacuum the computer, paying special attention to cooling the processor.

    2. Thermal paste has dried out

    The second most common cause of overheating is the thermal paste between the processor and the heatsink drying out. When dried, it conducts heat poorly, which leads to overheating.

    The solution is to replace the dried thermal paste with new one.

    Tip: Don't buy the cheapest thermal paste. As practice shows, it also tends to dry out. More expensive and high-quality thermal paste will not dry out quickly and will not have to be changed again after six months to a year.

    By the way, good thermal paste In addition, it allows you to lower the processor temperature by several degrees.

    Life story:
    They once brought me a computer with a complaint that it was overheating. Having opened the case, I immediately felt something was wrong - a strong smell of mint was coming from the computer... Having somehow removed the processor cooler, I saw there instead of thermal paste... what do you think? ... TOOTHPASTE! It just dried out and then completely burned onto the processor.

    The moral of the story is: don't use anything without thermal paste. If there is nothing at all, then better cooling install without using thermal paste at all. It will be 100 times more effective than toothpaste

    3. CPU cooling is not installed correctly

    Sometimes due to careless installation CPU cooler moves out a little, which affects the cooling efficiency of the processor. Removing it and reinstalling it correctly may solve the problem.

    TO incorrect installation This can also be attributed to the case when the computer assembler simply forgot to remove protective film from the cooler before installation - this also happens. The film does not conduct heat, and it can also burn to the processor so that you can’t get it off with anything.

    4. Insufficient cooling

    If you have a powerful hot processor and simple cooling, then it may not cope with high temperatures. Each processor in technical specifications The heat package is indicated (in Watts). And each cooling has a characteristic called “power dissipation” (also in Watts). So, ideally, the dissipated power should be at least slightly higher than the thermal package of the processor.

    If your cooling cannot cope with the temperature of the processor, there are two options - change the processor cooling system to a more powerful one, or artificially lower the processor power through the BIOS. But you and I are not perverts, are we? I'm definitely not

    5. Poor cooling inside the computer case

    Insufficient ventilation of the case leads to a gradual increase in temperature inside it, which leads not only to overheating of the processor, but also everything else.

    The reasons may be either an insufficient number of case fans or an incorrectly designed case ventilation system. We'll talk about the design of cooling systems later, and in order not to miss anything, subscribe to update articles by email, it's free and doesn't seem to hurt at all - so far no one has been hurt

    6. Insufficient ventilation of the space around the computer

    According to the standard, there should be at least 15 centimeters to the left and back of the computer case free space. This is necessary for better air circulation - heated air should leave the case freely. If this does not happen, we get a gradual heating of the air inside the case, and then it’s not far from overheating.

    7. Overclocking the processor

    If your processor is overclocked, it will heat up much more, and overclocking can easily cause overheating. When overclocking, more powerful cooling systems are usually used, and if yours cannot cope with high temperature, then either remove overclocking or improve the cooling of the computer.

    This concludes the list of reasons for the computer processor to overheat. Remember that ideal cooling will never allow the processor to overheat in normal mode, no matter what load it is given.

    I assembled a system unit from purchased, new spare parts. The following problem occurred during startup (OS is not yet installed):

    1. I launch the system manager, log in normally BIOS Setup
    2. BIOS Setup shows the processor temperature. As soon as I enter BIOS Setup, it is at about 52-55 degrees and then quickly drops to 45-47, where it continues to remain. I can wait for many minutes - the processor temperature does not increase.
    3. I change BIOS settings, click save and reboot. After this, at the POST stage of the download, one long and three short beeps, is shown "CPU Over Temperature Error, Press F1 to Continue", I immediately go into the BIOS settings - the processor temperature is already at 75-77 degrees, but again quickly drops back to 45.

    Those. The problem is that when I reboot, my processor warms up from 45 to 75 degrees in a second, causing an error.

    Possible sources of the problem

    1. Bad thermal paste. First, I applied the thermal paste that came with the cooler to the CPU. After I immediately received the error described, I removed the cooler and generously greased everything with ZM-STG2 Super Thermal Grease. The processor itself is pressed tightly to the motherboard by the mount, and the cooler is also pressed to the processor.

    2. Overclocking timings. I didn’t make any settings to overclock the computer, as soon as I unpacked the motherboard from the box, I installed it with those settings.

    3. The fan on the PC cooler does not work. I took off the side cover of the case, checked it - everything was spinning. I touched the cooler's radiator - it barely warms up (that is, it feels like it does not remain cold, but takes on heat).

    4. The problem with the power supply is too high voltage, voltage surge at start. I don’t know how to check this, the power supply is also completely new.

    What other options might there be?

    Components that make up the system unit:

    1. Intel processor Core i5 2500K, 3.4 GHz

    5. RAM DIMM Samsung 1333MHz DDR3 4Gb x 4 pcs.

    6. nVidia video card GeForce GTX 550Ti, add. power connected

    Note: at the specified motherboard There are many temperature sensors, based on the readings of which it independently regulates the rotation speed of all coolers. So, right at the very moment of reboot, it accelerates the coolers to a loud howl, and then when everything cools down, it works absolutely silently and does not heat up.
    Those. this fact confirms that the processor heats up sharply not during operation, but precisely at one moment of reboot.
