Will the CPU shut down automatically if it overheats?

The CPU will automatically shut down if it overheats; this is the CPU's self-protection mechanism. When the temperature exceeds the limit it can withstand, the CPU will automatically restart or shut down the computer in order to protect itself from damage. Reasons for CPU overheating: 1. The fan of the CPU radiator is broken and cannot dissipate heat well; 2. The computer exhaust port is blocked by dust, preventing the heat from being discharged from the computer; 3. Defects in the design of the computer itself, such as the chassis Poor air duct design; 4. The silicone between the CPU, graphics card and heat spreader has aged, resulting in low thermal conductivity.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The CPU will automatically shut down if it overheats.

If the CPU temperature is too high, it will automatically shut down or restart. This is a normal phenomenon of the computer.

In principle, the phenomenon of automatic shutdown when the CPU temperature is too high is actually caused by the CPU. In order to protect itself from damage, the CPU automatically restarts or shuts down the computer. Our CPU has a self-protection mechanism. When the temperature exceeds the limit it can withstand, it will automatically restart or shut down.

#The reason for excessive temperature is heat dissipation. The most important thing is that there is a problem with the heat dissipation of the CPU. Mainly include the following points:

Causes of CPU overheating:

1. The fan of the CPU radiator is broken and cannot dissipate heat well.

Solution: The fan needs to be replaced. For some original radiators, a radiator needs to be replaced.

The CPU performance is good, but the power consumption will be higher. At this time, you need to use a better radiator to be able to withstand it. If the radiator used is too poor, it will also cause the CPU temperature to be too high. For ordinary CPUs, an ordinary 4-tube radiator is sufficient.

2. The computer exhaust vent is blocked by dust, preventing heat from being discharged from the computer.

Solution: Clean the computer regularly.

3. Defects in the design of the computer itself, such as poor air duct design in the chassis, will cause the internal temperature of the chassis to continue to be high, causing the CPU to also be high.

The air duct design of some cases is poor, which will cause the internal temperature of the case to continue to be high, causing the CPU to also be high. It is necessary to modify the case air duct. If it cannot be modified, then change to a case with better air ducts. For In some dusty areas, it is best to buy dustproof ones.

4. The silica gel between the CPU, graphics card and heat spreader has aged, resulting in low thermal conductivity.

Solution: It is necessary to scrape off the original deteriorated silicone grease and replace it with good silicone grease. (Requires disassembly)

Note:

If the CPU is overheated for a long time, it will damage the transistors in the CPU, cause damage to the surrounding hardware, and accelerate aging and performance. decline.
