phase changeWhat Is Phase Change Cooling?

with phase-change you can cool your CPU to sub-zero temps. Sometimes even as low -150C but it costs a lot of money and energy...

Actually, reading over the original post again, this is nothing like a fridge, its probably more akin to a lava lamp. It isn't proper phase change cooling like the technology inside a fridge, this just uses convectional current inside the heatsink's pipes to move the substance from a hot end to a cool end. The substance doesn't actually need to change phase for this to work, but it probably makes it more effective as the density/buoyancy of the substance would change more dramatically making the cycle faster. The only think you probably need to look out for is to make sure you have the heatsink oriented the right way up. Make sure the cold part of the pipe is above the hot part otherwise this won't work at all.
