Mikhailtech take a look at Swiftech's complete extreme water cooling kit, the MCW462-UT, featuring a huge radiator, an awesome waterblock and a massive 226watt TEC (thermo-electric cell or peltier).
You can see the TEC just between the waterblock and the copper cold plate in the picture above. Speaking of the TEC, the one on MCW462-UT is rated a huge 226W and heats up like hell on one side, while the other side is below 0C. But this kind of TEC needs a lot of power. It uses a standard 12V rail, but it can also use a 15V rail if you have a special TEC PSU. The biggest problem is the amperage, because the TEC is rated to require about 20-24A from a 12V rail. This is pretty high, since most 300-350W PSUs only have 18-20A on the 12V rail. More powerful PSUs like the 400-550W version might have enough power for this TEC, but only a select few.More information at Mikhailtech
