May i know what is the cause to make my cpu temperature keep rising? Cpu and psu fan working properly and my cpu temperature keep rising when i check in the bios. Once open the computer then the temperature keep rising from 30 celsius to 80+ and shut down itself. I've just formatted the pc from windows xp to 7. I tried changing psu but the temparature still keep rising. Gigabyte p55-ud3l mobo and i3-530 proc.
