          @phaedrux That's the problem. The extruder fan, NOT the part cooling fan is running full blast. Allways. Usually these fans turn on after T45celcius automatically

            Sorry, can you clarify which fan is connected where?

            What happens when you send M106 P1 S1 H-1 ?

              Sorry but I don't understand what you mean by that.

              I was wanting you to verify that whatever output you were using was still working.

                Ok. First things first.

                Phaedrux, I sent M106 on config file. Nothing changed. Fan stays ON no matter what. FAN 1 was added as option on DWC screen, but it cannot be controlled, which is correct, as the fan is connected in a non PWM output.

                dcwilt, the extruder heater fan and the motherboard fan are connected in a NON PWM output, but they allways stay ON, full blast no matter what....
                I wanted to turn them on via thermostat, as they should work. Am I missing something???

                    Yes, M106 P1 S1 H-1 will disable thermostatic control and turn the fan on. Send M106 P1 S0 to turn it off again.

                    FAN 1 was added as option on DWC screen, but it cannot be controlled, which is correct, as the fan is connected in a non PWM output.

                    Fan1 port is indeed PWM controllable.

                    Fan0, Fan1, Fan2 are controllable. Plus two more always on fan ports.

                    Which are you actually plugged into?

                    Fan0 1 2 can be used as thermostatically controlled or by the slicer to set speed for part cooling.

                    The always on ports are... always on.

                    If you send M106 P1 S0 and the fan won't turn off, then either it's plugged into a different port than you are expecting, or the fan mosfet has been damaged and failed in the on position.

                      It sounds like you are referring to the "always on" fan outputs - they are not controllable.

                        I have plugged those two fans on the allways ON ports.
                        So, after reading your comments, I assume that they cannot be thermostatically controlled???

                          They cannot be controlled in any way. They provide power to the connected fans when power is supplied to the board.
