Just out of curiosity has anyone ever tried chain TEC's? Put a water block on the CPU, then have a series of water blocks and HSF's with a TEC sandwiched between them? If each TEC can pump say 30 watts of heat and you chained enough in series, in theory you could pull more heat out then a the CPU could put in, your coolant could go subzero at least till it's freezes. And if one water block HSF pair didn't have a TEC at the hot end it could work as a moderator. Or other ways to moderate it.
