Essentially the following snippets aren't working

[multi_pin part_fan]
pins: fan_part_cooling_pin, fan_part_cooling_pin_2
[... much futher down...]

[fan]
pin=multi_pin: part_fan

[multi_pin part_fan]
pins: fan_part_cooling_pin, fan_part_cooling_pin_2

[fan]
pin=multi_pin: part_fan
shutdown_speed: 1.0

However the board light for FAN3 light up correctly and when switching wires the other fan spins correctly. 🤷‍♂️

Line 52 - don't alias an alias. Just directly reference those pins (in your case PD15 and PD12). Line 278 should be formatted line pin = multi_pin:part_fan Otherwise it looks ok to me. And now that you don't need that extra alias you should just use the normal board include instead of your custom one

I get the exact same thing I don't use PD13 for the electronic enclosure as mine is open and air cooled. So even when I plug an extra fan in PD13 and set the config to

[multi_pin part_fan]
pins: PD15, PD12, PD13

[multi_pin part_fan]
pins: PD15, PD12, PD13

the extra fan doesn't spin Why does PD15 and PD14 works and not PD12/13?
