How low can you go?

[advancedkill]

I know that this forum is about overclocking, but I had another idea.

Back in "the day", the first CPUs etc. weren't cooled at all. My question would be, what temp could you get a core 2 duo/quad to without any cooling on it at all? I think this would be very interesting.

lol i booted a cpu without the cooler on it once

took the skin off my finger lucky it grow back

I don't even think that todays PC could boot a CPU with the low clocks required to run without any H/S, even if you think back to the days of the commodore i think i am right in saying that they ran 64bit, yes that fast and the chips used to get hot, and the old 486 chips used to have some kind of passive H/S to keep them cool.

So i would not like to try as these new chips get very hot very quick.

Surely if you ran one at 10mhz it would be pretty cool?

Still don't think it would boot with such a low clock even if you could set to a min of 10mhz, but even then the voltage would be far to high to run the CPU without a H/S on and would soon burn out, just try this, as baz said take your H/S of and just boot for a few seconds and hold your hand on the top of the CPU, you will soon find you have burnt your fingers within seconds of the PC being on, any longer than a few seconds and it will just burn the chip out.

Intel chips have thermal cutout at 130c and a high end socket 478 with no heatsink would just about have enough time to make bios and get to hardware monitor before it shut down.

Maximum PC did that once, with an X6800. It wouldn't go past 73C on idle.

Not only what sacha said, but you wouldn't be able to run it at that speed, as the FSB only goes down to 200mhz, and the multiplier down to 6.
