I have a Fractal R4 and I feel that I need two extra fans in the build. The case can hold two front fans, one bottom fan (excluding the power supply fan), one exhaust fan at the back, and two fans on top.
I already have the bottom front spot and the exhaust fan spot utilized by the stock fans that came with it. Also, I have an H100i taking care of the top spots. That leaves room for two fans. One on the bottom in front of the power supply , and one in the front.
What would you suggest? And would you suggest me replacing the stock fans that came with the case?
