I personally care about noise
what I do is open notepad and find the max rpm for every fan at 3 noise levels:
1) just audible, quiet room, headphones off
2) max tolerable/not annoying, quiet room headphones off
3)just audible, headphones on
picrel is the curve on two of my gpu fans
similar to other fans/groups
besides this you have to balance the intake/exhaust to get the pressure you want, I go for positive so the filtered intakes always total higher airflow than the exhausts
