Phase Exchange cooling is the same way that refrigerators work. Take a gas, compress it into a liquid, allow it to vaporize into a gas (absorbing heat), take the gas elseware, cool the gas down (release the heat), and then compress it into a liquid again.

Problem is that if you want to go fanless, phase exchange is not for you. Phase Exchange is great if you want to freeze your CPU not just cool it. Not to mention that Phase Exchange will only add to the heat that you are trying to get rid of. I would just stick with a basic liquid cooling system and find a very large passive radiator of some sort or find an alternative method of disapating heat. BladeRunner came up with a great idea however it is unique to his geograpical location. Too bad others can't benefit from his idea.
