I gutted my old PC and got a nice fan driven Pentium CPU heat sink and a small on board graphics chip heat sink (on the right, in front of my beer; it was an old company PC, they weren't bent on gaming performance)
Now to glue the TEC in between with heat sink compound, go test it all and mount it on top of my airbox. The tiny GPU sink will be the hot part inside the airbox; the springs tightened to maintain contact with the TEC and the top cooler.
Yeah, the Pentium cooler is a bit overkill. The copper contact patch feels uncanningly cold even at room temperature as it is so efficient at drawing heat away.
The GPU heat sink feels cold too - but heats up between my fingers in seconds.
I hope it is big enough - it just fits the TEC.
