fan1 speed control

[roei910]

hello,
i wanted to ask if there is an option to set the fan speed on the fan1 pin, i am currently running a 5015 fan on the hotend.
full speed is very noisy and has some vibrations so i wanted to run it at a lower speed.
was wondering if there is a way to do that with this firmware.

thanks.

Fan control depends on the board, for example for the Creality 4.2.2 and 4.2.7 the extruder fan is directly connected to power supply, so no control is possible.
