What is the reason for the high CPU temperature?

It is said that the estimate of changing the fan does not know the situation. My Kyushu Fengshen copper fan, the cpu on the new computer is only 39℃, but the Celeron cpu is still soaring to 50. It depends on what kind of CPU. Some CPUs are high-powered when they are manufactured, and high power is bound to have high heat, as in the early Celeron.

My old Celeron will exceed 70℃ even when playing flash games, and it will soar from 40℃ to over 50℃ as soon as it is turned on. It seems that the CPU is aging, and some friends think it is caused by the unstable power supply of the motherboard. In a word, these are hardware problems that we can't solve. I seem to be better for a few days after I brushed the BIOS, so I think the voltage is also the mastermind.

My policy is to use it and replace it with a new one if it breaks down.
