This I need an engineer on this idea.

If I'm getting this right off of Wikipedia (which seems to be overwritten by some idiot now), the Peltier effect is two things:

• A voltage is present in a circuit when a difference in temperature exists between two points in a circuit.
• Applying a voltage in a circuit will chill one point and heat up another point, forming a heat pump.

I'm probably wrong on the latter point, so correct me here (thus the need of an engineer).

The idea, however, is this:  Take a regular powered Peltier to chill any modern CPU (say, an AMD Semperon).  Add another Peltier to power a fan to help cool everything down.

I don't know the mathematics behind it, so I'm at a bit of a loss.  AMD however recommends that chips do not go above 45 degrees C.  My laptop is cool at 25 degrees C, so you have a base point there.

The better chip designs are still in the laboratory. Synthesized crystalline-diamond substrates that are porous for forced air cooling *on the die* to eliminate large, cumbersome heat-pipe and fans on heatsink affairs that are all too common today. That baby's being built in my back yard at the moment. Other ideas I have read journals on include closed loop liquid cooling built in-die as well. I have seen working prototypes of CPUs that have little tubes of phase transitioning coolant circulating, ambient air temps more than enough to re-condense the liquid after it moves from convection currents through a small radiator. It promises faster, smaller designs with built-in cooling solutions that should last the lifetime of the product. But I bet you as soon as it's released in the public, some overclocker's gonna make it better. ;> Even seen "vapor misting" cooling solutions involving PC's with boards and CPU's hermetically sealed with sprayers blasting Flourinert around the insides like a dishwasher does dishes. There's some wild crap out there!
