Deciding on fans in SFF case (Geeek A30)

[green_reaper]

As the title says I'm looking for two 80mm fans for the geeek A30 and I also won't be using any HDD/SSD space so I should be good as far as extra maneuvering. I was about to get the Noctua redux line of fans but I'm not sure if I understand fans well enough to know if that's a downgrade from the brown Noctua fans. can anyone let me know what my options are? Which is more optimal? static or air flow?


Redux - https://noctua.at/en/nf-b9-redux-1600-pwm

Brown a9 - https://noctua.at/en/products/fan/nf-a9x14-pwm

(these are the 92mm options im looking at to replace the fan on the noctua L9A cpu cooler. )

The brown a9 is actually worse than the fan the l9a comes with, its is practically the same model as the one that comes with it but a slower rpm so it will not cool as well. The redux is meant to be a case fan not sure how much better it would perform if any

I went for a budget-conscious choice for those since I was disappointed about my 92mm noctua Redux fans I can't use in the A30 lol

I bought 2x Arctic cooling 80mm PWM fans and they're doing a geatg job and very silent at low rpms.
