My setup is a 360mm rad on the top of the case as exaust, two 140mm fans in the front as intake, and a 140mm fan at the back as exhaust. There are two 120mm fan mounts on the bottom of the case and was wondering if putting a 120mm fan on the bottom as intake would improve the airflow in the case. If the one fan on the bottom won't make much of an impact I'll just go without it. Thanks!
