Hello,

i dont know why but i cant control the Speed of the FAN0 for part Cooling, it only starts on 100% , 99% just make it stop... on my old creality mainboard there was no problem, since i installed an fan with more power i only run it at 80% cause 100% makes noise :D well the Axis are now Quiet but my fan is noisy now xD any suggestions ??

It may depends from cooler model & PWM freq.
