Below is my current fan setup. I drew it up in paint. I am not sure if my push/pull is setup to be optimal. I have a NZXT Zero 2 case. Overall there are 7 fans currently in the setup not including the CPU cooler which is an Asetek LCLC. or the built in graphics card fan Six of the fans are 120 and the top is 80.
I fail at understanding the entire push/pull methodology and I think my setup is alright. I have and OC Core i7 920 to 3.4ghz now and sit at anywhere between 34-40C idle. I am about to add in the top fan now and have it marked for pull. My PSU cage is at the top of the tower and not the bottom.
