PWM Fan Question (beehaw.org)

I realized I have a spare port on my motherboard to control an extra pwm fan (in addition to my blower fan).

Given the option, would it be better to use it for my hotend fan or for my part cooling fans? I’m primarily looking to reduce noise while printing (I have a pin completely cutting power to the fans when the machine is idle).

Are you asking about adding a fan, or moving one of your fans from non-PWM to PWM?

About changing one of my fans from non-PWM to PWM (Can I control DC fans with that same header?). I need to buy at least 1 more Noctua A4x10 fan anyways, so I'm wondering if it's worthwhile to buy a PWM one for this purpose.
