P600s - ditch the rear fan?

So I'm trying to get the right fan configuration in a new P600s build, aiming for slight positive pressure to limit dust intake as much as possible.

I have a top-mounted 360 AIO with 3x Noctua NF-A12x25. This is obviously capable of exhausting a great deal of air, depending on the fan speed. Front intake is a pair of Noctua NF-A14.

In an attempt to balance the intake and exhaust and get positive pressure, I'm wondering if it would be better to remove the rear exhaust completely?
With both the AIO and rear exhaust, surely I'm going to have trouble getting positive pressure without running the front fans faster (and thus louder)?

Lastly, I'm just using the basic BIOS fan profiles which are based off CPU speed. I've seen mention on some sites of using Fan Control in Windows to get better control and also potentially key off GPU temps. Is this something people would recommend or just stick to simple BIOS profiles?

Fan configuration and balancing always does my head in :)
 
Yeah my BIOS only appears to offer control based on CPU temp. This is generally ok and how I have things in my current machine as CPU and GPU temp generally rise and lower together when gaming. I just thought the additional control of the Fan Control software might be useful, will have a play.

Flipping the rear fan to an intake is obviously the next step after simply removing it and I might try that.

I don't actually have a GPU in the machine at the moment. Once that's done and the build is complete I may start playing and doing a proper smoke test.

I have the P600S with an Arctic 280 AIO in the top and three Arctic 140m in the front, using Argus Monitor to control fan speeds. I have the front fans always spinning slightly faster than the AIO and have hardly any dust inside(very fine particulate is all). The mesh and the filter work really well but you need fans with good static pressure.

So you're not using a rear fan at all?

My GPU is now installed and I've been playing around with Fan Control to get not only the profiles/curves right but also balance the 2x140 intakes with the 3x120 exhausts. Still not sure what to do about the rear.
 
Just spent a couple of hours configuring the fan profiles in Fan Control and have positive pressure at all loads.

At full load the front two NF-A14s need to be at 90% to overcome the three NF-A12x25 exhausts so I think I'm going to put a third NF-A14 in the front so I can lower the speed a touch.

You want more air going in then you can exhaust hence giving positive pressure.

Did you reverse the rear exhaust to an intake?

Nope, removed the rear fan completely. Problem with reversing it to an intake is there's no dust filter which defeats the object of positive pressure.
