Best Positive pressure fan setup?

[DayQuil_Man]

Going for a positive air pressure setup in my first build.
Whats better: 3 140mm fans in the front for intake and 1 in the rear for exhaust causing hot air to leave through the rear and through the top vents. Or: 3 140mm in the front and 2 140mm on the top both for intake and having the 1 140mm in the rear for exhaust?
The fans are Noctua NF-A14 industrialPPC-2000 PWM, so they are very good.
The case if a Cooler master mastercase pro 5 which includes filters.
And I will be running a Noctua NH-D15 as a CPU cooler which has 2 fans blowing into the rear exhaust.

Your option #2 would not be positive, it would be neutral because there is the same amount of intake as exhaust. I can tell you that personally, I run 3 140mm intakes and 1 140mm exhaust, and my case has very little dust and my components stay very cool. Positive is generally good. You could do 3 intake and 2 exhaust. That may actually reduce temperatures a bit more than 3 intake and 1 exhaust.

So what would you reccomend, front 3 fans for intake and 1 fan rear exhaust
or
front 3 fans intake and top 2 for exhaust

I'd run 3 intake and 1 exhaust, and if you're unsatisfied add another exhaust. I doubt you'll be unsatisfied. It's really good to have high air pressure in the case. More air particles to come into contact with a given surface area per given period of time and cool from contact. In addition air gets crammed into all the little spots where it may not reach otherwise, such as hard drives and the dark abysses of the case (maybe that was too far). And less dust.

Thanks for the help.
One more thing, would you mind sending me a link to your pc parts, Im just curious to see what parts you have (since you said that airflow option works good for you) and see if its similar to mine
