A little info about pelts. Seeing as most are rated for 18V, you'll never get that full 226W of cooling power. Also, most power supplies don't have heavy duty enough wiring to handle the power going to that pelt. Finally, you'll need either water cooling or phase along with the pelt, as the pelt will generate heat equal to whatever its cooling power is (it is just a mini refrigerator after all). Most people don't use pelts for those very reasons. What sounded like a $20 attempt to chill your hardware to sub-zero temps now becomes several hundred dollars that still might not be 100% reliable. If you're still thinking of it, Pinhead and Tuchan know more about it than most people do. Pinhead and Tuchan both use 437W pelts running at 9V through a seprate variable PSU.
