Okay, so I've enabled "Smart Fan Control" (essentially, fan curves) for my intake and exhaust (CPU cooler already had it enabled). I'm seeing better temp "recovery" after getting a hotter, but my intake is very noisy lol
Yup, I will replace and add another fan for intake, because this is not PWM.
I did not remove most of it, and I'll do a gaming + 3DMark test in a bit.
