When the fans are placed in front of the radiator and air pushes through them it’s called «push». Reason being, there isn't enough flow resistance to effect air movement. Exhausting air form inside the case through a radiator may give you a few degrees higher CPU temp in games because GPU makes a lot of hot air. I would get a reversible electric fan and have it switch every so often to clear debris like they do on tractors. As mentioned in a reply to another comment here, I will go ahead and add in a small push-pull test to the Nemesis GTR … Having a plenum between the fan and radiator lets the airflow change direction more gradually, reducing both turbulence and noise. If you’re putting the rad in the back/side part of the case, the front panel cables are a pain in the ass We continue our guides that show differences in radiator performance depending on the speed of the fans, thickness, and FPI of radiators etc. I want to set the top radiator as intake and on pull. I don't know about fan aero... although I do know bearings and motors a bit, and would say for fan reliability, push is less heat on the fan motor's bearings. Push, pull, or push/pull?
