Well said Don, but kiko is implying his/her PC is running normally ohterwise, just noisy. Oops, just reread the first post, and it says that the PC is shutting down by itself spontaneously. Patrick gave kiko the first good advice, and I just added to it. If kiko prefers not to use the paste, its OK with me, as its not my PC I was trying to save from catastrophic failure. LOL. PC's are cheap these days anyway.
I would not want a overheating CPU to shut down. But it is good protection for the CPU. But can damage the motherboard.
Many times it can melt the solder on a BGA CPU or melt a plastic CPU socket.
Some people drive when the Oil light on their auto comes on, and wait till the motor blows, then check the oil. Same with water temp light. I call them DA indicators.
I like to fix something at the first sign of trouble. It is cheaper that way.
But as you know it is easy to be a pro crastinator.
