12V fan on 24V supply #19

24V fans are pretty hard to find. On the next revision of the hardware it might be nice to include a jumper to select either the 12/24V rail or the regulated 12V supply for the fan outputs.

If you have the M5 board it has that capability.

You could just change your max fan pwm to 120 in the config_advanced. So you'll get 12V on 100% :)

(please measure with an multimeter to get your correct max pwm value)

PWM and fans don't work that way. You'll still give pulses of 24V to your fans and depending on the fan it will take damage. I agree, a jumper solution for 24, 12 and 5 V is the way to go here
