Could you find a way to deal with the caps, mofsets, and memory freezing to the point where they are not functional......no. Don't see any (reasonable) way to do it. From that standpoint this idea is dead.
Maybe you could use C02 in a cascade chiller? At least we know you could somehow make that work. Yes, it would be cold. Yes, you would be using a rediculous amount of electricity. Yes, it would be EXTREME.

You know, the idea of using such a system is more of a thought experiment than anything else really. While I was thinking of this idea today writing my previous response, one other problematic issue occurred to me.
Assuming all these other issues are taken care of, one issue remains: namely, how do you turn the thing on?
If you try and turn the processor on after the thing has reached "operating temperature" you will thermally shock that processor, and probably crack the die in the process. Obviously, if you turn the processor on first, it will be dead before the coolant system will matter. Maybe a speedstepping proc would make a difference if its supported, but the processor won't last long getting cycled up and down like that anyways. This would even matter between running at idle and max is the gradient were steep enough. The third option is a gradual rise in either the cooling system capacity, or the processor speed. While that idea could be made to work with a ton of money and work, it doesn't matter.
No matter what you do you end up with a rig like what I see posted all the time at xtremesystems.org. Basically a top fuel dragster that can't do anything more useful than post 3D Mark scores. Not what I'm after for sure.
