Yeah, but no, its a 50mm and a 40mm peltier. and I wasnt planning on stacking peltiers. I just decided to do it because I could

see what kind of temps I can acheive. If I am really feeling up to it, Ill see how cold I can get my duron 850(stock 45watts) It wont handle more than 60 watts any colder than it would be with just the 226 Im thinking.
-edit-
I calculated my cold plate temp to be around -66c Lets see what happens
