Fan speed controll?

I have a azteeg x5 mini v3

I can’t seem to control the fan speed, when i enter a m106 p190 fan will not run, i have to enter full speed p255
now fan turns on if i enter a p200 after fan start, then it will shut off tried 2 different fans same results they are
24v fans and i have a 24v power supply connected.

Any suggestions?

Thanks gary
