this thread is hilarious....
Phase change cooling is cool, and more than just literally... but the sort of thing you're doing is just dumb. There is a reason people pay upwards of a grand for a reliable phase change cooling system, and I garuntee it doesn't have to do with looks.
Personally I wouldn't even trust a top grade water cooling system... things DO happen. Defects emerge, pats go bad... and all it takes is one drop of water in the wrong place to fry a very expensive system. It's a real nightmare. Phase cooling is a little bit better provided that it doesn't use electrically conductive liquids, but it's still unecessary stress on your system. Any exotic cooling system has issues... it places more strain on your CPU for one thing. You can OC the latest Intel chip to 5GHz using liquid nitrogen, but the chip would probably expire from the stress before long, and you'd also risk shattering something at those temperatures -- the faster you heat/cool something, the more stress you put on it.
Invest in a large heatsink and a good fan.
