Fan Setup of NZXT s340 Using Only Air Coolers

Hey there. I know there are a lot of topics out there about fan setup of NZXT s340 but they generally have different coolers or strong GPU & CPU. The system i am planning on getting is Ryzen 5 1400 and GTX 1050 Ti and i will be using 720p monitor since i already have it now. I wont be using any water or tower cooler just the stock fan that Ryzen 5 1400 comes with so nothing fancy ^^ These components are not that high and definitely i will not be doing any overclocking. I will simply play games. So i am kinda confused about the fan setup.
As you know NZXT S340 comes with one rear exhaust and one top exhaust fans which are 120 mm. I could simply

* Take the top exhaust and install it as front intake.
* Take the top exhaust and install it as front intake and add a Noctua NF-P14 Redux-1200 as second front intake. I dont know if the combination of 120 mm and 140 mm would cause any problem though i can't see any reason for it to do so.
* Or simply leave the stock fans where they are and add two Noctua NF-P14 Redux-1200 as intake.
The thing is i dont know if there will be any significant temperature difference between these 3 formations considering the components of mine and me not be doing any overclocking. So what do you think i should do ? Thank you in advance.

  1. It all depends on if you want a positive pressure or negative pressure.
    With positive pressure, you need to have more intake fans than exhaust and with negative pressure, vice-versa.

    I'd take 2x Noctua NF-P14 Redux-1200 fans, install them as front intakes while leaving stock fans as they are and call it a day.

    Uh sorry for the late reply i was kinda busy and thank you for your reply :) Now i am thinking of the second formation taking the top stock fan (120 mm) and move it to front as intake and getting a Noctua NF-P14 Redux-1200 as intake as well providing a lot of positive pressure i believe ^^ Do you think would that be okay simply with 2 intake and 1 rear fan with this case ? And having a 120 mm and 140 mm at front as intake togethor would cause any problem ?

  3. 120mm and 140mm as intake fans together at the front won't cause any issues.

    2x intake and 1x exhaust fans are quite decent for cooling aspect. This way, you have quite a strong positive pressure and only way where the dust enters your system is through intake fans. So, filter them if you can.

    The nf-P14 is a good, all around fan, decent for either rad or case, but excels in neither. You'd be better off with something along the lines of the Phanteks F140-SP, which are just as silent as the Noctuas, just as reliable, but will move a ton more air, making for better airflow. They also look better and have led options.

    2x decent intakes and 2x exhaust is optimal for any mid atx case or smaller. All you need is the air inside the case to actually move, the speed of which is of less importance than the fact that it actually does move.
