Cooling setup question

[dreamartz]

Hello!

In my previous build I had NZXT h440 case with Kraken x41 aio. Temps were OK but case was extremely dusty even after just couple of days after cleaning. I got my cable management on point and clean my room regularly. PC was just collecting every god damn piece of dust like a f***king vacuum cleaner. So I had this setup in that build:

Radiator placement: TOP, 1x 140mm NOCTUA NF-A14 3000 PWM. EXHAUST
Case fans:
2x 140mm NOCTUA NF-A14 FLX FRONT INTAKE
1x 120mm TOP stock NZXT case cooler. EXHAUST
1x 120mm BACK stock NZXT case cooler. EXHAUST

I guess I just messed up with positive/negative air pressure in case and right now I just did my first big upgrade and want everything to be smooth Have following cooling setup right now:

Radiator placement: FRONT, 2x 140mm stock NZXT coolers. INTAKE
Case fans:
2x 140mm TOP stock Phanteks case coolers EXHAUST
1x 140mm BACK stock Phanteks case cooler. EXHAUST

I don't really care about noise, just want it to be less dusty. Any suggestions on improvements and etc.? Thanks a lot.

Current specs:
Case: Phanteks Evolv Tempered Galaxy Silver
Cooling: NZXT Kraken x62
MB: Gigabyte GA-Z270X-Ultra Gaming
CPU: i7 7700k
GPU: MSI GTX 980ti
RAM: 16GB Corsair Vengeance 2666mhz
Storage: 1xSSD + 2xHDD
PSU: Corsair RM850

Are you missing front dust filter. It should collect and prevent dust from entering the case. Even with the dust filter some dust does enter into PC but it shouldn't be as bad as you are saying.
