r4 and fan placement

[Dojf]

Hi, I was thinking of building a new PC with the Fractal Design r4 and was wondering about the fan setup.

2x front intake
1 top exhaust
2 rear push/pull for my h80i

Will this produce positive/neutral or negative air pressure, I'd like to have positive air pressure because of the dust build-up.

Thanks!

A proper push/pull will suck the air from the case, offsetting any fans you have blowing into your case. If you want more positive air pressure inside the case, set up the radiator fan in reverse push, sucking the cold air from outside the case to cool the rad, and all the other fans mounted to blow air inside.

Okay, Lets see if I get this right .. So no exhaust fan? Just take cool air from the back and have all fans as intake's or did I missunderstand?

If you don't mind me asking, what is the best cooling solution if you disregard the positive/negative pressure?

How have you setup you're r4 rig if you don't mind me asking?

Well, you mentioned you wanted positive air pressure, which I took to mean you'd rather have all air blowing into the case.

The way I'd set it up would be to set up the rear rad with two fans in push/pull, exhaust out the top, and intake in the front, like you indicated originally.

Alternatively, if you have space around the rear of the case with access to cold air, set up a fan sucking outside air into the rad, suck more cold air from the front fans, and exhaust out the top. This is assuming you have the case sitting on top of a desk open to the air of the room, rather than tucked in a computer cubby.
