I wired the blue to ground and the red and black to the upper fan header. set the correct voltage.
Included my printer.cfg and picture of my wiring.

i also tried [fan]
pin: !PA8
cycle_time: 0.01
enable_pin: PA3 and then moving the ground wire to heater pa3. but there is no life what so ever...
i see the picture but not the printer.cfg
if you disconnect the pwm wire, does it spin up to 100%?
the fan does nothing when the pwm wire is disconnected
then most likely it is dead
it should run 100%

pin: !fan_part_cooling_pin
cycle_time: 0.01
enable_pin: PA3
