spfd, That is almost what I would have said about 3 weeks ago. I didn't have any idea what one was either. But I found out they have been around since the early 1900s.
From what I've read about them, they are heat pumps. You can get them in a lot of sizes. I've seen 40mm to 70mm. And they are about a 1/4inch thick. When you applie voltage, they "pump" heat from one side two another. And they do so good, you can have as much as, or more than 75 F deg. difference from one side to the other.
If you use one, you can go way bellow ambient. But the draw backs are, they add almost almost as much heat, as they pull away from your CPU. Making your case temp a LOT higher.
Thermaltake makes a heatsink that uses a peltier. The sub zero or something like that. (www.thermaltake.com
) It has a controller card that keeps it at ambient case temp. so you don't have to worry about condinsation. But it runs at about $90-120.
I just purchased a peltier off of ebay for $11 (counting shipping). It's one of the smaller ones I've seen. 85-105watt. 40mm. I got it so I could experiment with it.
I've also heard the military uses them in reverse. They use propane to heat one side, and air cool the other side. When you force heat through the peltier, it generates electricity. And it must work pretty good too.
I've even heard it suggested to use a peltier in place of a car alternator. Just put it on the engine block, and it will charge your battery. (Not too sure it would work well though.)
Zero Shift. Sure, I'll let you know how it goes. It may be some time before I get everything together though.
