I am new to thoughtful fan placement...(Probably explains the thick coat of dust on everything). I was wondering what is the best fan setup/system for the NZXT H440 case. There are three 120mm (nzxt FN V2)fans in the front of the case and one 140mm at the upper rear. I have the Corsair h100i with two 120mm fans on top. What would be your suggestion for optimal cooling in my situation? eg. what should be intake/exhaust?
