Direct contact watercooling!

http://www.xtremesystems.org/forums/...d.php?t=222040 -- this guy seems to get good direct-die results with slightly chilled water.

I've been looking for the lowest temps with the least power consumption. Although it is true that lower temps will allow the same clocks at lower voltages = lower overall CPU power consumption (which I'd be willing to allocate to the cooling)

There seems to be some conflicting evidence for direct-die cooling here. I though I "knew" that it wasn't as effective as using copper to expand the surface area, but uh... I'll look into it again later.

Phase-change is tempting, but I just can't justify the power/noise.
