I have wondered about this too, probably act as an insulator and overheat the cpu even faster.
Ultra - does your controller throttle back on the TECs when your on light load? ie reduce power consumption when your not benching or gaming? I reckon the dual pelt will get more attention than the single as people wanting this will want to overclock it as far as they can and still have cold temps. When the TEC's cooling capacity is exceeded do temps skyrocket or just slowly creep up?
