Wouldn't this make the best GPU cooler?

Apparently it's called the Peltier effect.

What?

I bought a peltier like those (the plain blank square of 60x60), placed the cooler side in the processor and the hot surface on the cpu cooler. I got bad result. Would need a secondary cooler to cool the metal (cooper) and this cooper to reach the cpu surface somehow. Just google it, people aready use  it this simple.

You are thinking of thermoelectric effect / cooling and it is an active type cooling the requires power

Basically the more heat you want to move the less efficient they become and traditional methods are better.
