MACS Kooler TEC Heatsink
 

TEC cooling has a few drawbacks compared to a regular HSF setup, the main
one being that it's cooling is usually so efficient that temperatures will
drop to below ambient, which means that you will need to insulate against
condensation. This kind of setup also usually requires a separate power
supply and more often than not, watercooling to cool the hot side of the
TEC. But take the middle ground of a low power TEC coupled with a HSF
combo, and while the temperatures won't drop below ambient, they should
get down lower than a HSF combo alone.

Stupid, no HS (and especialy no alu) can handle the load of a 122w tec + another 100w of the cpu.
