Got the 14g fermenter and peltier kits from stout. Bought 10A peltier chips on the web (not sure the source). The coolers BARELY got cool. After a quick tutorial on Peltier chips on wiki, i figured i wasn't pulling enough heat off the hot side of the chip with the fans and heatsinks supplied with the kits. I bought bigger fans and heatsinks and, luckily, i could use the hardware in the new kits to get the new heatsinks to attach to the stout aluminum blocks. Now they get relatively cold. I can get down to 49F in a 70F room with only a single wrap of the aluminum 'bubble wrap' around only the body of the fermenter (not the cone or lid). I have two kits, so 4 chips and 4 fans/heatsinks.
Currently running a run of the mill 725 watt computer power supply to power the whole thing. At 12v the chips should each have ~120 watts of cooling power in an ideal setting. I would guess that at 40A, that power supply is not delivering 12v so probably not an optimized setup. I plan on more insulation and a different power setup in the very near.
