You can check if it's a slicer issue by manually turning it on using
M106 S255

yes, I used 24vdc 50x50mm fan.
But i started manually from Control/Temperature and I saw that it start turning only at 130 (out of 255). That would ne like 50,98% . Somehow there is not enough current or something to start from a lower speed. I used a smaller fan and that is working nice from 40 to 255.
So, I will try to set in Cura minimum fan speed 52% to see what is going on.

That does sound normal if your fan draws a lot of power. Cooling fan outputs are kinda limited. Does it work well at full speed? If your duct concentrates a large fan to a small area, it will add resistance to the flow of air and slow down the fan. Especially with non blower fans, they are not designed to deal with pressure well. It may be worth trying to remove the fan fem the duct and see if it operates at lower speed better. If it does than the fan and duct are not compatable.

Just tell me the dimension between the mounting holes..... |
