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.
