The rule, all machines and mechanisms have a property to heat up during operation and computers are no exception. And they can overheatThat often leads to failures, malfunctions and even physical damage to components. Most often, overheating of computers occurs due to a poorly operating cooling system and accumulate dust in the case, but this trouble can be involved at elevated loads, especially in hot summer weather.
To avoid unpleasant consequences, it is important to be able to determine the signs of overheating. Only here how to do it right?
To monitor the temperature of the components of the iron, the special utilities receiving data from the temperature sensors are correct than all, but also to pay attention to external signs, the main of which are:
Noticeable reduction in overall performance, freezes
Spontaneous shutdown of applications with access to the desktop
Spontaneous shutdown or restarting computer
The appearance of interference on the screen
Exit BIOS asking Check Cooling
Unusually strong fans noise
But it is better, of course, do not wait for their appearance. As already mentioned, it is necessary to use specialized utilities for measuring temperature. True, such tools on the Internet pond pond and not all of them show the same information, so the user may have a reasonable question: and which of these utilities is most adequate?
In our opinion, such is a powerful diagnostic tool of computer iron. By the way, in addition to measuring the temperature, this program can make a lot of other things starting from providing more information about the system and ending with processor tests and RAM. But in this particular example, we are interested in temperature measurement. Find the temperature indicators of the processor, individual cores, video cards and its memory, diode PCH (South Bridge), Hard disk and motherboard chipset.
N RMoot: The temperature of the RAM cannot be measured with a software method, since there are no temperature sensors in the Module itself.
Normal and Critical Indicators
For processor or individual nuclei heating to 40-50 ° C. with an average load is considered normal, and before 55 ° C. - permissible. Temperature 60-65 ° C. is potentially dangerous 70-80 ° C. - Critical, in which serious violations are possible in the computer, in particular, the fall in Bsod., Converted application operation and spontaneous reboot of the computer.
With video cards a little more complicated, since everything depends on the models and their purpose. With the average and high load of the video card of the latest models can hear up to 60-65 ° C. And this is quite normal, whereas for old models such a temperature will already be considered close to critical. Signs of overheating video cards are usually artifacts - image distortion, appearance on the screen stripes, squares, change color gamma, etc.
For most hDD rigid disks normal temperature is considered to 30-35 ° C., 40-43 Celsius is already elevated, above 45-50 ° C. - criticalat which the appearance of failures when reading / writing and bad-Sectors on the magnetic surface of the disk.
Optimal temperature chipset motherboard Consider 30-40 ° C., on some models, he can warm up to 50 Degree. In general, with overheating of this component, it is rarely encountered, so we will not pay special attention to him.
Yes, still in There is such a wonderful tool as "System Stability Test"allowing you to obtain data on the temperature of all the main components of the computer under one hundred percent load. It is in the menu Service and is a separate window in which you need to set all the checkboxes and click "Start". Next you will only be monitored for monitoring data.
By and large, this is all you need to know about the temperature of iron of your computer. As for the methods of dealing with overheating, it is described in abuse. Installation better cooling systems and regular cleaning from dust - This is usually enough to ensure an acceptable temperature mode.
There are many different sensors in the computer, thanks to which you can track the temperature of each element. In the AIDA64 program, you can track all temperature sensors, including the PCH diode. What is it and what temperature should be, we will learn from this article.
Diode pch what it is
That what is a diode PCH and what is its normal temperature. After all, most computers and laptops, the temperature of the PCH diode is kept in the area of \u200b\u200b60-70 degrees. Compared to other sensors, you might think that the temperature of the diode is overestimated.
What is a PCH diode in aida64
In the section Sensors in the AIDA64 program, there is such an element as a PCH diode. In the temperature monitoring programs, thus denotes the northern bridge. On the motherboard, it is placed as a separate chip and a small radiator is placed on it, this chip is responsible for the operation of the processor with RAM and the video card. In the photo below you can see how the diode looks like something.
It is also worth noting that on some Motor Board models the North and South Bridge can be combined into one chip. This is often found in laptops.
PCH diode is one of the main elements on the motherboard. In case of failure of this element, the computer will stop turning on. And the replacement of the northern bridge (Diode PCH) is quite expensive and there is no guarantee that it will no longer happen, it is easier to buy a new motherboard.
PCH diode What should be the temperature
Many personal computer users want to know what should be the temperature of the PCH diode, that is, the northern bridge. There is always a question related to the temperature, there is one answer: the smaller the better. 🙂
On most computers or laptops, the PCH diode keeps the temperature in the area of \u200b\u200b60-75 degrees and this can be considered the norm for this diode.
If you have noticed that the temperature of the PCH diode is above 75 degrees, it is worth making measures to reduce temperature. It's time to clean the computer or laptop from dust. The fact is that while the computer or laptop is operating, the cooler which is located inside the system unit, chasing the air. Dust that is present in the air settles on radiators and thus worsens the process of cooling the elements, so you need to regularly clean the computer from dust. In addition, it is still necessary to change the thermal paste. You need to change the thermal accelerant on the processor, as well as on the PCH diode, which is under the radiator.
If the diode overheating was seen on the usual computer, the problem is solved by installing an additional cooler, but most often the purification of dust eliminates this problem.
PCH diode overheats. What could be the consequences?
The constant overheating of this chip, that is, the northern bridge (PCH diode) can lead to failure. A rather common symptom failure of the diode is a black screen when you turn on a computer or laptop.
The cost of replacing the northern bridge is about 60-70 dollars, which is quite expensive, while there is no guarantee that the same problem will not appear again. The best option will be purchased a new motherboard, because for the same price you can buy a normal motherboard.
There is no such person who would be unfamiliar symptoms, accompanying colds - the decline of strength and body. Sometimes the latter reaches such high values \u200b\u200b(up to 40 degrees Celsius), which must be taken to reduce it. But if it is quite familiar and familiar, then the owners of computing machines will be interested to know that even the temperature of the computer is sometimes rising.
Although it has little to do with human diseases, excessive heating in the same way requires control and (sometimes) interference with the work of components.
At first glance, it may seem to understand why the temperature of the computer is increasing and what to do with it is the prerogative of service centers. This is not quite so. Workshops can be compared with hospitals. And independent control and the adoption of simple measures, thanks to which the temperature of the computer remains within acceptable limits, with prevention. Well, the latter, as is known, more preferable.
Unfortunately, specify what computer is impossible. This affects the class of installed components - powerful allocate more heat and for them the concept of permissible norm above. It can be estimated that the value of 70 degrees is the limit. Accordingly, the norm is up to 50 Celsius. The question more reviews below.
Why is the temperature of the computer grow? Everything is simple: inside the system unit or laptop housing there are electronic components that are highlighted with heat during operation. It is easy to understand if you remember that the electrical current passing through the conductor causes the latter heating. By the way, that is why many have high hopes on which there is no present phenomenon.
The main sources of heating are: video card (especially discrete models), some elements of the motherboard.
The first two of these components consist of millions of transistors, each of which is distinguished by a bit of heat during operation. To remove it on devices, placing cooling systems - a metal radiator and a fan-envelope. By the way, the noise of the working computer occurs just due to air flows from rotating blades. Then everything is simple: when the cooling system is covered with dust (which is inevitable), the efficiency of the heat sink drops, and the level of heating increases.
The result is as follows:
Decline in the performance of the entire system;
Spontaneous reboots, frequent hangs and other failures;
Distortion on the screen;
The impossibility of loading when the corresponding item is involved in the BIOS settings;
The output of components is out.
This is what the excessive temperature of the computer can lead. A program that allows you to check the levels of heating, called AIDA. This is a powerful diagnostic application that can "tell" about all the features of the installed components, including their temperature.
After downloading, installing and starting, you need to select the "Computer" section. The current components of the main components will be displayed: boards, processor, video cards, hard drives.
Thus, the "diode PCH" indicates the heating of the main board, it should not be higher than 65 degrees; "CPU Package" - a central processor, not higher than 70 Celsius (can be viewed separately by nuclei); "Diode GP" is a video card, not more than 70. To find out the exact values \u200b\u200bof permissible temperatures for installed components, you should go to the manufacturers' sites, specify the type of component and read the permissible heating values. For example, if the Intel processor is installed on the computer, you should go to the appropriate site, specify the type (for example, COREI3-2120), and in the specification table to find the permissible heating temperature.

Q: Diode PCH burns, laptop slows down
Laptop Dell Inspiron 3521.
The PCH diode began to warm, even in idle mode, the laptop was warm, the PCH diode in AIDA64 shows 60-72 degrees, but if you open the lid and touch it with a finger crystal, you can get a burn after a couple of seconds. Bashes everything terribly, although it worked smoothly before that. There is no direct radiator at the PCH diode. The laptop stands on a wooden table next to the open window (the temperature in the room is low enough). I do not know what to do and how much will the repair go and is it in general the case of such terrible brakes. There is a chance that it started after the entrance to the entrance for headphones, on the same. I would be grateful to any advice to correct the problem.
Answer: The nest of the headphones with the audio codec is connected, it in turn with PCH, so dependencies are not direct, maybe the nest is bad or badly soldered.
Question: HP Pavilion DV7-5000ER) warps and goes out the screen
Every year I spend cleaning the lattice lattice. After another cleaning, the laptop was collected as usual and the temperature for this laptop is normal, but after a small load (CS GO), a minute, the screen goes out, but the laptop does not turn off. When stressing the AIDA64 test on the CPU, nothing exhausted everything worked as it should. But when stressing the test, the Furmark screen goes out, although the temperature is within the limits of allowed and even lower than in the stress test of the CPU (except for the temperature GP - 86 against 72 and the Diode PCH - 85 against 84). BD82HM65 chip is very hot and it seems this northern bridge (red). I also noticed that the part of the board is very hot, where the power is connected (green). I checked the voltage at the BP output issues 16 V although it must be 18.5 (I do not know how much it is critical).
Answer: Power must be at least 18.5V, the power supply is replaced. By the way, it may be warm due to poor contact, not tightly connected to example, then the voltage can dry out in this place, with concomitant heating.

Question: The Intel Core i5-3210M processor is heated
Hello. The Lenovo Y580 laptop has an Intel Core i5-3210M processor. Easy is heated from 50 to 60 degrees. In stress, the CPU test in Aid is heated to 73 degrees. But if you turn on the GPU test, it begins to warm the intellectual HD Graphics 4000 built into this processor. It seems to be in it and there should be no temperature sensors but in the Advanced Systemcare and GPU-Z programs it is determined and produces a temperature in simple 55-65 degrees and about 85 degrees after 3 minutes Stress test. Discrete GTX 660M under load more than 65 does not produce. What could be the problem? The processor came the end?
Answer: magirus.When the laptop was disassembled, it was relatively clean and the dust was not enough. After cleaning the temperature did not change here, probably the problem in the other, because the processor itself heats up to 73 degrees as much as it seems not much. And the Intel HD Graphics 4000 built into it is heated. As soon as it gets up to 85, it comes out for a second the screen and exits the error "Intel HD Graphics Drivers for Windows 8 (R) stopped answering."
Many users with their computer or laptop, such as their beloved, pay attention to the presence of a certain element called diode PCH For which the temperature is also displayed.
PC components temperature in AIDA 64
And there is a completely appropriate question here - what is this PCH diode and what a temperature should be. Indeed, in most laptops and computers, the temperature value for it is displayed in the area of \u200b\u200b70 degrees, which, at first glance, it may seem a lot of elevated value.
What is the PCH diode?
Under such a designation in temperature monitoring programs, the Northern Bridge is usually there. It represents a separate chip on the motherboard, which is responsible for the operation of the processor with RAM and the video card.
Radiator on the PC motherboard, under which is the Northern / South Bridge
In some modifications, the North Bridge is combined with a southern bridge and / or a video card in one chip.
Laptop motherboard bridges and video card
Thus, the PCH diode is a very important element of the motherboard, which, upon failure, makes it impossible to work and launch a computer.
What should be the temperature of the PCH diode?
Of course, the most correct answer to this question is the lower, the better. But in most computers and laptops it heats up to 70-75 degrees. And this in principle can be considered normal temperatures.
When the value of 75 degrees is exceeded, it is worth thinking about cleaning your computer or. In laptops Very often between the cooling radiator and the northern / south bridge there is a thermal stroke, which when cleaning the laptop needs to be changed.
In the system block, the problem with overheating of the PCH diode is solved by installing an additional cooling cooler.
Installing an additional cooler on the radiator of the Northern Bridge
Consequences of overheating of the PCH diode?
Long overheating of the northern bridge (PCH diode) leads to degradation of this chip. The symptoms of this process is / computer.
The replacement of the northern bridge in the laptop costs about 60-70 $, depending on the model. On PC motherboards, its replacement is impractical in mind the comparable value of this procedure with the value of the new motherboard.
