My build (when I finally get all the stuff in the mail) is going to have a 200mm front intake, 120mm bottom intake and 120mm rear exhaust. My MB has 1 "power fan" I assume this is to control the psu fan, and 2 case fan headers (besides the cpu fan header of course). Is the best idea for this just to use a splitter on the 2 120mm fans? or should the splitter be on the 2 intake fans?
