quote: um if you're running an AC unit into your computer I think condensation is going to be another part of your troubles.

quote: The basic problem is such engines have difficulty varying their power level while still remaining efficient.
quote: I don't think so. Let's be honest. First of all an axial fan (as small as that one) can't really create any pressure at all. In the picture there's a big gap between the heatsink and the fan. There's no way that fan can really move air through that heatsink without ridiculous rpm (and noise).
quote: And of course the mechanical energy is converted right back into heat in the operation of the fan -- the second law of thermodynamics.
quote: the heat generated from the motion of the air itself will exactly equal the energy used to power the fan. Inescapable.
