You are maximizing the airflow in this case, but you are going to be adding a lot of noise. If I had that case I'd install 2xCorsair AF 120mm in front. They are quiet but blow. Then install a 1100rpm ball bearing fan on the bottom. And lastly a quiet exhaust fan.
The focus is on quietness and that is one of the reasons people choose the R4. It's an excellent case and designed for low noise so make sure to get the proper fans too.
