an interesting idea

[Voodoo Rufus]

Liquid helium would be cool if silicon could handle it, but at a coupel degrees above absolute zero, the CPU would die very quickly, even if the CPU were slowly lowered to that temp. Hmm, a 4GHz Athlon?

i think the silicon could take it if it were lowered at a constant rate and capable of maintaing the temprature with a minimul fluxtuation which is totaly improbable you know you will have a fluctuation of 4C or so which is enogh to expand and contract just enough to crack said core. if they only designed cpus for extrem cooling measures by giving the chip room to contract without crushing the links.

The silicon will retract from the core anyway with prolonged exposure to extreme cold. It is a dead CPU definitely at LiHe temps.
