Just started the final details of my build….

Hooked up axial flow fan to the FAN1 set for PWM control. Fan works fine but horrible noise when not at 100%.

If I change the PWM value to something like 500 (seems to be the default for the online configurator) do I go higher or lower to possibly get the fan to quite down?

Thanks

I tried going from 500 down to 250, didn't seem to make a difference in the noise. I guess since the micro controller directly handles each PWM output, I was going to try upwards but didn't want to go too high (wondering what the upper limit might be).
