My water cooling setup was phase change as well but with the water loop in between the evap coil and the cpu, instead of putting the evap coil (block) directly on the die. This really brings up the question of how they are insulating the back of the board then, since direct die phase change cooling will give you even lower temps than a water cooling setup would. My record low was in the mid twenties (fahrenheit), running about 40/60 antifreeze and water. Ahh ok.

How stable is this thing? I know it's water cooled by the best and everything, but no hard numbers are presented. Overclocking is a joke: The challenge is stability.

The tube running to the CPU has (I'm assuming an inlet and outlet water pipe, and both of them are surrounded by insulation allowing chilled water to pump through the waterblock without causing condensation in the case. The block itself appears to be thermally isolated from the case as well. The only problem I ran in to is the motherboard is thin enough that the back of the board would build up ice around where the socket was. Covering it in rubber insulation and dielectric grease did the trick, but was super messy. I'd like to see the back of the motherboard in that setup. Another factor was noise. There were no fans in my setup and the water pump was fairly quiet, but running a 1/4hp window A/C compressor (even without the fan, the evap. coil was submerged in an acrylic water reservoir built around it) sounded like there was a lawn mower in my room. What kind of noise does this generate? But at 5.46GHz who cares I guess? :-) That is an awesome design for water cooling.
