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 cant hear it work, this is very impressive.
Chip-cons 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 Prometeias compressor
hardly notices the CPU is there.
