So I just bought myself a nzxt kraken x63 and when I was playing fortnite I mostly cap my fps at 144 and now it going 80-90 fps. And the temperature are fine and my old cpu fan was giving me higher fps, it was a intel fan.
Specs:
CPU: Intel Core i7 8700
GPU: Nvidia Geforce RTX 2070
PSU: Nzxt kraken x63
MB: ASRock B360M IB-R1
Really need help.
