How cold is water cooling

[JAP901]

What is the coldest temps you can get using waster cooling? thanks everone

[phiber]

depends on what type you could run peltier setups and watercooling and get sub zero temps...

Just using regular water a nice water setup will usually cool to a few degrees above ambient.

You can also add pelts to a water setup and bring the temps below ambient but that requires a lot more work and care.

the reson I ask is I thought of using freon to cool the water cool sys but i have read if you get below freezing the cpu chips will crack and damage the cpu. so I was checking with yall to see how cool i could keep an O/C system

[Warlord2]

the chip would have to be I think -50c in order for it to crack so I think your alright

I think a couple of people are using freon setups here that can help you out more

In contolled phase change setups (direct on-die refrigeration) AMD ran an early T'bird @ 1G in 1998 at -50C. There are a number of people running similar setups at present. There are no real problems with current refrigerants. I am running sub-0 as you can see. There is research going on at some of the engineering labs to try to achieve 0K (-270?C).

Water cooling is usually above ambient no noise!

You can add extreme mods like a TEC or a peltier that will go down to sub zero temps but you need a powerful water cooling set already because you need to cool it DOWN to get sub zero.

I heard anything some what close to -100 Celius will cause the CPU to damage.
