View Full Version : Freezer cooling?
Hi there you coolers
Is there a minimum temperature for the comp to run properly. Will it Freeze if i go under 0c or will it produce super conductors =P
Well I know that the CPU, NB, and GPU can take temps below 0C... I don't know about the boards themselves... I think that's how Colin's 9600xt died, he hooked up a vapochill to it. Not sure if that's what did it or if it was just a defective card.

you can go as low as you can, just gotta watch the condensation. the lowest ive seen someone cool a cpu was like around -90C with a dual cascade phase change cooler. at least i think it was -90

If the cpu was made out of the right material and if you could cool it enough, you could make it superconduct, which would mean that electrons would flow with *zero* resistance. That means no heat production and wicked fast computations!

All you gotta worry about is absolute zero, but nobody needs to worry about that...yet... :) Are there specific requirements for superconduction?
The requirements for superconduction? Having the right materials. Gold and cobalt can be when pretty pure. The normal right conductors like nickel and F can be too i guess, im not sure. I was not serious when talking about making a superconductor though =p. Even if some parts were in the right metals, and pure enuf to go for it, it would propably not work as not the entire computer would conduct fast enuf. In theory u need something like -60c to make a superconductor i think. Im not sure, it makes pretty long since my physic lessons at school.

I do believe the coolest is -190c.

Cooling with liquid nitrogen.

yes, but that was by no means constant. LN2 is incredibly unstable, and if I'm not mistaken Tom's guys fried that CPU during testing. Macci has had the lowest constant temps I've seen anywhere at -90C using his dual cascade:

But no Raftah, CPUs won't lock up at below 0C temps. Mine runs -25C on a regular basis (Prometeia MachI). The only thing you need to worry about are condensation (completely seal the area around the vapor phase head front and back of PCB) and moving mechanical components such as HDDs. When HDDs get too cold they start to have major problems writing data to the spinning platters.
