I am rebuilding my gaming PC in a new case (AeroCool DS Cube). This case has an interested setup for fans. I overclock slightly, and have a pretty power hungry build, so I am upgrading the fan setup. For the record, CPU cooler is a hyper 212 evo.

It comes with a 120mm 35.4cfm fan in the rear as exhaust and a 200mm 36.4mm fan fan in the front for intake.

I plan on purchasing 3 140mm fans for exhaust (2 on top 1 in back), they are rated at about 40cfm. For the intake I plan on using a 200mm fan rated at 184cfm.

So I'm going from a pretty balanced 35 exhaust to 36 intake to 120 exhaust to 184 intake. Is this a healthy balance? Should I do anything to adjust this ratio?

Slightly positive fan pressure will reduce dust buildup in your system.

The chances of making any significant change in pressure in the case are zero .

Intake fans tend to be quieter , but thats about it
