How long will a system last without any cooling?

post #1 of 16
Thread Starter 
Title says it, how long will a system last without any cooling on the chip or anywhere else? no fans either, that is if it will boot without any fans. Just out of curiosity

wont even post without shutting down thermally. I've tried this on an old p4 with no heatsink.

Depends on what chip it is and the voltage pumping through it. The AMD Sempron 140's have been able to live for a while without the use of cooling. Most of intel's low end dual cores can also be run without a fan, depending on how low you undervolt them. Your chip, however, will be shut down in seconds without cooling to protect the chip.

A mainstream->high end chip would probably throttle itself down and make it to the OS boot before turning itself off via thermal protect.

A low power CPU would probably throttle down, but still operate. I remember a video of someone testing this on a E2140 and they were able to keep it running for sometime since it was generating little heat. I believe once they applied solid load it shut down.

My GF has a computer that I ran constantly without a heatsink. It was a 1.5ghz celeron. It got to about 60c idle. lol.

So i don't know if that one would ever thermally shut down. I was able to drop the idle temps to about 40c just by sitting a heatsink on top of the chip, even without TIM.

depends on the system, I have some old pc's without colling

but today, most if not all pc's need to be cooled in some way
