for cooling, thye are pretty effective if you can keep them cooled themselves.
basically, it takes the heat from one side of the pelt with an electric current, and transfers it to the other side. you need a really good HSF to keep it from overheating on one side, but the other CPU contact side should remain very cool, and provide for great cooling.
disadvantages : takes power, and sometimes ALOT of power. some run on seperate PSU's that you hook up to PCI slot, kind of a "pelt controller" for it and fans and stuff.
if you flip it the wrong way, you're F-ed. the hot side will toast ur CPU.
advantage: prety good at keeping cool, and they aren't as troublesome as a watercoolign kit.
