Hey everyone, I am doing a new build soon in a p500a. I have 3x140mm pwm fans and 4x120mm pwm fans. The configuration i was going to do was 3x140mm intake in the front and 3x120mm as exhaust through top and 1x120mm exhaust through rear. Will the 140mm fans warrant enough intake to be positive pressure vs 4x120mm exhaust? The cfm on them are 56.3 on the 120mm and 72.8 on the 140m. If the 140mm intakes won't overpower the 120mm exhaust is my only option with what I have to just set the 140mm intake fans at a higher rpm than the exhaust fans. Or do you reckon I could just daisy chain them all together at the same speed and still have positive pressure?

Sorry if this has already been asked, Thank you.

Also, the fans I own are the arctic p12 120mm and the arctic p14 140mm pwm fans.

Edit: I also thought I should mention im using an air cooler for my cpu.

A)Using a tower air cooler.
Front: intake, 3x 140mm.
Top: nothing.
Rear: exhaust, but depends on the specs of the cpu cooler's fan. If the fan in question has weaker specs than the fan on the cpu cooler, then leave it empty.

B)Better gpu cooling - at least with axial fan cooled models - but cpu cooling takes a hit.
Front: intake, 3x 140mm.
Top: exhaust, 2x 140mm. 3x 120mm with a ~400mm long gpu.
Rear: exhaust, but depends on fan specs like before.

C)Using a top-down air cooler.
Front: 3x 140mm intake.
Top: 2x 140mm exhaust. 3x 120mm with a ~400mm long gpu.
Rear: exhaust, 140mm.

Take your pick, I guess.

I have 3x 140mm intake, 1x 140mm exhaust, and on top nzxt z73 3x 120mm exhaust. Do you think is that good?
