Opened up my case today to clean it and prepare it for a couple new parts I ordered and I noticed something. Can't remember if this was a mistake, I did it for a reason, or if it was the optimal choice for airflow efficiency but...here's a diagram: The green boxes are 2x80mm fans and the red arrows are the direction of the air. My question is about the upper two fans above the power supply. The way they are facing looks as if they are creating a circle of air up there (pulling in air, psu takes it in and spits it out, that air gets pulled in again and repeats the process). That's not right...or is it? Do I need to turn the two around so they are exhausting air like the rest of the fans at the back of the case?
