Currently i have the HAF 932 AMD edition with an Intel i7 6900 and a H100i gtx cooling it mounted on top. But i have a 140mm fan on back case, 200mm @ 110cfm i think on front and side. The side i know ( not sure about front ) will take a 200mm ( if its designed to fit the 230mm holes ), 230mm fan or 4 x 120mm fans. Just wnana push more air flow to keep things cooler exspecially more air flow onto my EVGA gtx 1080 FTW. Theres a bitnix 230mm fan with 156cfm @ 900rpms but not sure if id get more air flow and/or cooler air with a 230mm or 4 x 120mm and which ones would be best. Trying to keep it all red led's.
