I was just thinking about real extreme cooling, and I recall that Helium is the coldest possible liquid (yes/no?).

So if a CPU is <0ºC will it freeze up and become unfunctional?

Here's an LN2 pot running LHe:


Source= XS

Below is an image of the internals of the LHe pot made especially for this purpose. Previous LHe pots
simply blasted LHe at the base of a traditional LN2 pot and were incredibly inefficient.

CPU's aren't made of water....

didn't the guys who hit 6 originally with the 940 BE close to absolute zero (neg 270 C) with Helium? If I remember correctly - I thought they were within 10-15 degrees of that.

I think it was around the January, mid to late timeframe...

Duckie - do you remember?

they hit around -270C or 5k to 10K

any lower and the entire cpu is garbage....and i doubt they can get to even below 5K because hardly anything in the universe is that cold except that of complete void of nothingness...

they did a good job on the OC though but i just wish they could have come up with a more reasonable way to OC like a more stable 24/7 OC not a 90min worth of it at like thousands of dollars and totally ruin the cpu...

the goal should be to OC the best stable 24/7 system...not a race to see who can get the fastest because you will never see anything stable....

i mean with lHE i am sure that the 920 could reach 6.5-7ghz....and the 975 extreme can hit almost 7-8ghz...

Nope. Impossible (Unless we are talking Fahrenheit). Tell me what liquid could do that. We can't get get to absolute Zero let alone colder than it.

At the AMD events it was running in the 240s and 250s.
This does not ruin the CPU either....they work fine after, as long as they don'y pump over 1.8V through it...which they never do
And no, the i7s cannot go under liquid helium because they will cold bug and stop functioning. There has yet to be an i7 chip to hit 5.6GHz+

Also, the helium is all for fun and games to see how far we can push a technology.

liquid nitrogen boils at 77k or 196c. i dont think that anyone cooling a cpu got anywhere near absolute zero
