Wow, 3 325w TECs....?
I'd planned on 2x 15v VMax 350w TECs running at around 8-9v. (I've bought a 40A 3-15v variable PSU for this)
Do PSUs really dump that much heat?
My graphics card is more like 50w, but you've forgotten to add 6x h/drives @ around 12w each = 70-75w
It's a lot to cool..... Maybe I will have to have a dedicated water loop for the CPU afterall, instead of using the TEC's to cool the lot.
