About 10K = -263 C. (rough figure. May be a little higher. Certainly Nitrogen
is one of the higher temperatures. Liquid Helium is a lot colder. About 4K
IIRC).
Don't do this. Ever. Water cooling is safe if you buy the correct bits and are
careful. Cooling with nitrogen is suicidal: you'll not be able to cool it
evenly, fiberglass is very brittle, and you'll crack you motherboard. Not
a good idea.
Why do you require this level of cooling anyway? If you're overclocking this
hard then do you still have a stable system? Or are you trying to put
8 way Itanium into a 1U case?! ;-)
