I just learned something today and perhaps you will too since no one mentioned it before.
There actually exists positive and negative air pressure in PC cases.Positive pressure
is created when there are more intake fans than exhaust fans so what this positive pressure does is it pushes the air outside the case.Negative pressure
is created when there are more exhaust fans than intake fans so what this negative pressure does is it sucks the air from outside into the case.
Obviously positive air pressure is better because not only does it push the hot air outside it also doesn't suck all the dust like negative does.
So, I was thinking, since R3 only has a fan controller for 3 fans wouldn't it be better to just put one extra intake fan at the bottom thus creating positive air pressure?
Does this sound good in practice as it does in my head?
Also I see that R3 in its specs has a fan controller, but where is it? Carbide has a fan controller outside just where the power button is, but I can't see such thing anywhere on R3, is it in a box inside the case which you then mount into an optical drive bay or something?
