Condensation is one thing I noticed immediately when I saw the one at comdex. It was dripping
with it. I figured though that if you had a temperature sensor which would control it, turning
it on and off, then this wouldn't be a problem since you don't need to get the processor cold,
just keep it not too hot. (Ok, keeping it cold *would* be best but the thought of dripping
water inside my case makes me very nervous.)
