Setting up intakes and outs for my case

[jovanovichmichael]

I got a aero cool p7-c1 case, and I'm putting a noctua df15 in it,
It has 6 fan slots in the case, for witch I'm getting 6 noctua sa12.

My question is how to configure the intake versus outtake fans. There's 3 fans slots in front 2 in top and 1 in back. I am aware of the benifit to positive pressure in cases.

To do the standard 3 intake front and the back and top being outs making 3v3 intake and out. However the 2 cooler fans will be right there blowing towards out and my gpu is a blower style so it's blowing out. All this has me feeling it'll be negitive pressure.

But I read that if I were to turn one of the top or back around it could create air eddies that cycle and warm up instead of exiting the case.

How should I set these fans up

In the front, out the back/top.

If this proves to be too much 'negative' (and it would only be slight if any), simply disconnect one of the rear fans, and see what happens then.

Is it worth disconnecting a fan to get positive pressure? I'm ok with cleaning the case now and again if it comes to. But what do you guys think about the thermal trade off loosing a fan versus getting that positive pressure

I'd leave the top front empty, so three in two out. There's a site (can't find link atm) that did a boatload of tests on different fan setups. Filling the top front slightly interfered with the airflow to the tower style cpu cooler (assuming yours will push towards the back) making it less effective.

Edit: here it is - whole thing is worth a read but the summary items are good enough:

I figured that I'd set the cooler blowing towards the back since there's only one outtake their, I thought the case could use a little more power pulling air through the whole thing stead of a In the front and out the top, curved trajectory

That can only be determined after the thing is built and running.
There are a LOT of factors that go into 2 degree difference one way or the other, or pos/neg pressure.
Cable management, specific case, all the other parts, whatever OC you may or may not have, room ambient temp....

People tend to overthink trying to get it perfect before they've even assembled it.

In the front, out the back. Adjust as needed, as time goes on.
