Title doesn't say much...

I am building my first PC, but the GPU is a little late, so I have some time to plan.

I am using Fractal Design Define R5 which comes with to Dynamic GP 14 and I bought two
Noctua NF-A14. My motherboard has only 4-pin connectors, so I can use PWM

The Noctuas are PWM, but the GP 14s are not.

I have not bought any dustfilters so I only have the ones in front, so I'd prefer front to be intake.

My question is: Should I have the two Noctuas in PWM, or should I run all of them with the build-in fan-controller, or doesn't it matter – it's winter (soon), so it'll stay cool anyway. (Were should I place the questionmark?)

I am planing to upgrade all the fans to Noctua.

If I run just the Noctuas I thought about placing intake in front and exhaust in the side. If all four I planned the Noctuas as intake to keep positive airpressure; one in front, one in top, blowing into cpu cooler (Noctua NH-D14) which again blows to the rear. The GP 14s exhaust through the side and rear.

All answers are apreciated. Tell me which one of the setups I should use or tell me what you would do. Thanks in advance.

P.S: If you feel like it please tell which direction my cpucooler should blow
 
Solution
99 times out of 100 it will be
Front and Bottom = Intake
Rear and Top = Exhaust.

Positive pressure is good for dust because you know all intake air is filtered.
Negative pressure is good for cooling because you know all air is being evacuated and there aren't going to be any "hot spots"
CPU cooler should usually exhaust out the back, they are usually built to support a push pull going that direction.
Having the CPU cooler exhaust out the top is a perfectly viable option too though, but then your fans are horizontal and i find they make more noise in that position because gravity pulls the fan blades away from the shroud but eh, it really doesn't matter.
