Part cooling fan PWM noise. #55

Hi,

I flashed the latest prebuilt binary on my SKR MINI E3V3.

Works well, but I had the issue of annoying PWM noise anywhere between 1-99% fan speed.

I tried enabling the soft pwm in config.h and reflashing, but that just resulted in a weird choppy fan.

I have a single 5015 fan installed.

I am stumped. Any ideas?
