Prometeia Phase Change Cooler - Prometeia Phase Change Cooler
Tue, November 26 2002 | 10:29AM | PermaLink Feedback?
Man when I see this I'm so jealous... =( XtremeSystems checks out the Prometeia Phase Change Cooler.

Anyway, the evaporation process happens in what Chip-con has named the “Micro-Freezer”. The liquid R134a gets poured into this small copper chamber where it evaporates quickly absorbing all the heat from our CPU. The gaseous R134a is then sucked back to the compressor where it is compressed to a higher pressure and cooled in the Condenser, where it finally condenses into liquid state again. The Condenser is basically a “radiator” with a fan on it, but it is a large 120mm fan, and the noise level is comparable to medium quiet air cooling. Very impressive indeed. And here is the best example of the efficiency of phase change : all the heat generated is removed by a relatively small rad and fan. While the display reads -40°C and you almost can’t hear it work, this is very impressive.

Chip-con’s Prometeia case goes down to about -40 to -38°C with an idle system. Under load it reads about -33 to -29°C with a heavily overclocked and overvolted processor. In short, I can say that the Prometeia’s compressor hardly notices the CPU is there.
