say i wanted to make a build with a horizontally mounted itx motherboard with a gtx 670 and i already own a hyper 212 evo. Would it be better to have a downward impeller cpu cooler and have the top case fan as an input rather than output, or would the hyper 212 evo work depending on the direction? the case i plan on using is the bitfenix prodigy, and i was thinking about getting the cooler master gemini to replace my evo.
i suppose i should include the board i plan on using in the build for a frame of reference.
