It's a great little cpu cooler isn't it?
You know, even though it says that it's a 12v peltier, you can jack it up to around 13.4 and still get good efficiency out of the hotside/coldside ratio - providing you have a good watercooling loop to cool the peltier off. That meanwell psu, even though it says it's 12v, will actually go up to 15. I've got my cpu block going at 13 volts.
I've used this swiftech peltier cooler on all my LGA 775's for, I guess, a little more than a year so I've gotten pretty good use out of it. Now, with me about to install my conroe, I should get hella good temps out of it.
