Critical temperature. Measures to prevent CPU overheating.

Of course, the most important and main part of any computer is the processor. As for the other devices - all of them either serve the processor, or are engaged in input-output of information. As a result, the temperature of the processor is very important for the normal operation of the computer, since its strong heating leads to its failure.

The critical temperature is the temperature at which stable operation of the processor for a long time is not possible.

At this point, it is necessary to make a correction to the fact that the critical temperature and temperature at which the crystals of the processor are destroyed - two different concepts. Unlike the integrated circuit, crystals withstand higher temperatures than critical temperatures . In the "integral", in addition to these crystals, there are elements weaker to the temperature effects. Already at temperatures in excess of 90 degrees, in the crystals of the processor, electrochemical processes are activated, which disrupt stable operation and lead to a complete failure of the system.

The critical temperature of the processor of each firm of the manufacturer differs from each other, therefore the user needs to know what are the limiting thermal norms of the processor installed in his computer. Usually these values are indicated in the product passport. Standard processors in laptops operate in a range - from 40 degrees (idle) to 60 degrees (with loads). Dual-core processors operate in a temperature mode five degrees higher.

Although there are exceptions. Studying this question, I decided to find out what the critical temperature of the intel processor is. Measuring the temperature of the processor using a special program, to my surprise (and frustration) found out that the "brains" of my computer operate at temperatures from 55 to 80 degrees. Decided not to panic and "went" for information on the site of the processor manufacturer, where he learned that the critical temperature of the processor intel Atom n450 is one hundred degrees! So, you do not even have to worry about overheating this type of processor.

In light of the foregoing, it should be noted that, nevertheless, sometimes it is necessary to carry out preventive measures to protect the computer (laptop) from overheating. To do this, it is enough to clean the CPU cooling fan and radiator. After all, when they are clogged with dust and clogged, the heat transfer of the system deteriorates, which entails its overheating, protection triggering, and performance degradation.

The condition of the thermal paste also requires periodic inspection - its drying leads to unfortunate consequences. If the fan still emits various noises after cleaning, the procedure should be repeated and, if possible, lubricate its bearing (bushing) with a droplet of engine oil. It is necessary to ensure that the ventilation openings of the computer (laptop) are not closed by anything, which would prevent free access to fresh air.

To monitor the temperature of the processor , special programs are developed that display the data of interest to the user. The wide range of these programs is provided in the worldwide network. They are all different and differ in their goals and capabilities.

In order to trace the critical temperature of the processor, it is necessary to simultaneously run the program and boot testing the processor to observe the readings. When the protection is activated, it is necessary to note the temperature data. The protection is determined by the performance drop and how the processor multiplier is reduced. This is the critical temperature at which protection of the system is configured. From the producer's point of view, this is the maximum temperature value for this type of processor.

Watch the temperature of the processor, and then your device will last much longer.
