Well first here is my idea get a water block that has the two barbs coming out the sides so I can put a peltier on either side of the water block. The water block would be inline right after my radiator. On top of each 72w or 80w peltier I am going to put a heatsink. I was looking at Joes list of good heatsinks and I was thinking of getting the Global Win WBK38 because it cools well and is realitively cheap. I was wondering if anyone has tried this method of cooling their water. If you have any suggestion please reply or if anything is unlcear tell me thanks.
