I've adapted an MKS GEN L V2.1 board to a Creator Pro printer and I've got it all wired up and working EXCEPT the fans. I'm new to 3d printing so I'm not sure how these fans are suppose to work. This creator pro had 3 fans, 2 on the hot end and one beside the motherboard. The radial fan on the hot end that cools the printer material hooked to the fan port on the motherboard and looks to be turning on/off relative to whats being printer, so that seems to be correct? When should the second hot end fan come on and should it match whatever the first hot end fan is doing?? When should the fan on the motherboard come on? Should I just wire it direct to the power supply to be on all the time the machine is one?

at the very minimum the part cooling fan (the one that blows onto the printed material) should be plugged into some sort of controllable port (CNC/PWM, doesn't really matter)
the one connected to the hotend and blowing onto the hotend heatsink should turn on whenever the hotend is heated up
and the one connected to the motherboard can be either on all the time or just on when it's printing, it really doesn't matter as much
I have mine set up so my part cooling fans are controllable by the gcode commands, the hotend fan is turned on whenever my hotend is >70C, and my mainboard fan is on whenever something is printing
