so im curious about something, the setup i have right now includes my fractal define r4 case that has 2 140mm intake fans on the front, 2 intake 120mm fans on the top that blow down on a radiator, and a 140mm exhaust fan in the rear.
i am replacing the stock front fractal fans with nf-a14 flx's and the top 2 intake have already been replaced with nf-f12's, and this may seem like a silly question, but with all that intake air pressure, do i even need an exhaust fan? seems like the air is just getting pushed out the back by itself just fine without the use of an exhaust fan, the reason i ask this is that i wanna reduce noise as much as possible and since im using air from outside of the case for the rad i thought it wouldn't be an issue if i took the 140mm exhaust fan out.
