Installing static pressure fans vs high airflow fans

[Roman_23]

Hello !

As i am kinda weak when it comes to pc hardware part i might just ask my concerns here.
Currently i am swapping my Maelstrom liquid cooler to a NZXT Kraken x52. Instead of the place where my currect two cooling fans + radiator are i wanted to mount an RBG fan(NZXT aer or Corsair HD120 rgb fan, both 120mm) + instead of stock fans on NZXT kraken, which as i understood are static pressure fans i also wanted to recplace them with NZXT aer or Corsair HD120, both 120mm.
Is this viable ? I have read that by replacing stock fans with NZXT aer(which are high airflow fans) i might lose some % of cooling. Is the loss really perceptible and risky in long-term perspective ?
And what about Corsair fans, are they static pressure or high airflow ? The idea is to modify my interior of the case to match my exterior RGB design(i have thermaltake c22 snow RGB case)
Will this also affect my case cooling overall, positive, negative or neutral air pressure, as i am planning to mount my kraken on the top of the case and 1 cooler will be on the back. No coolers are in the front.

Any advise is much appreciated! Thank you!

As far as cooling performance goes, you'll loose static pressure with RGB fans since the stock AER P120 fans are optimized for static pressure,
specs: https://www.nzxt.com/products/aer-p

Max static pressure of all 3 fans:
AER P120: 2.93 mmH2O
HD120: 2.25 mmH20
AER RGB120: 1.35 mmH2O

With Corsair HD120, the loss in SP isn't big enough to have long term impact. But with AER RGB120, you'll loose more than twice in SP since it's AF fan.

With top mounted rad as exhaust and rear exhaust as well, without any intake fans, you'll get negative pressure.

Thanks for the links and for a clear explanation, it really helped to understand. So this means that if i will have 3 static pressure fans, 1 on the back, 2 on the kraken radiator mounted on top, i will also need an airflow fan in the front for the intake air ? As for now, i will have only 3 SP fans which will push air out of the case and none AF fans to intake air from outside of the case

If you're happy with negative pressure then you don't need intake fans.
But if you want to achieve neutral or positive pressure, you need to install 2x 120mm front intake fans as well.
