Hi, ive just brought a Corsair 750d, i love the case but i want to fill the case with Corsair AF120 quite edition fans, but the thing is i want to keep my pc as dust free as possible, i know you do this by having positive pc pressure. There is two intakes in the front three 120's in the top and one 120 in the back. I know top fans should really be used as a exhaust but if i put the AF120s as intake to get positive pressure i would not be able to see the rings on the fans. So the real question is how much difference does possitive pressure make with dust it the case will i notice big dust build up with negative pressure over positive. Any response will be greatly appreciated, Thanks Chris
