I have a i5 3550p and a Geforce GTX 760 in a Fractal Design Define R4 case. I'm wondering how much aftermarket fans I should install (if at all), where to install it, and setting which ones as intakes/exhausts. I have NO intention of overclocking or setting up my GPUs in SLI or Crossfire and be pretty much running everything stock. I have have an idea that air should flow from bottom to the top but I need a little more help.
