What causes a PC processor to overheat?

Question

Processors

Hello. What Causes Your PC's CPU to Overheat? I changed the thermal paste, cleaned the dust, but it still overheats. The temperature ranges from 80-98 degrees Celsius. What could be the problem?

Answer 1

Thanks everyone for the replies. I solved the issue this way, lubricated the thermoplastic processor of the video card, tightened the cooler on the processor better. After that, the processor shows - 35 degrees, when starting games - 40.

Answer 2

Overheating mainly comes from the processing load on the processor, and depending on the processor, this temperature may be normal.
If this temperature is indicated in rest mode, then you should compare the TDP of the processor with the heatsink used.
Further, it is already worth considering the issue depending on other factors, how quickly the processor reaches this temperature when starting the PC, is there a normal space for heat removal, etc. etc.

Answer 3

If overheating is due to video games, then perhaps the power of the video card is not enough and it shifts the computational load on the processor. Also, not only mathematical processing, but also graphical calculations are possible on the processor. Although in a good case, graphics should be handled by the video card, namely the video card chipset. Apparently he can’t cope, or there are very high video requirements for the system requirements of the games used.

Answer 4

Sloppy cooling system, for example. You can also apply thermal paste incorrectly.
In general, tell me the processor model and which cooler.

Answer 5

In addition to dust and thermal paste:
- lack of ventilation inside the case or bad (this is possible even with a large number of case coolers, you just have to confuse the air flows)
- fan speed control (s) does not work correctly
- poor heatsink pressure to the processor
- poor contact between the heatsink and the processor - curved/concave surfaces of the cpu and/or cooler
- abnormal operation of the processor. Even if you did not change the settings yourself, the motherboard may automatically set the voltage by mistake.
- you are a "lucky" owner of modern Intel CPUs (1150, late 1155 sockets). For unclear purposes, instead of solder, Intel used an incomprehensibly very bad character as a thermal interface between the chip and the thermal distributor cover. When using some kind of boxing misunderstanding and an unsuccessful copy, I will completely believe in overheating even at regular work.
