Controller fan on Octopus Pro 446, config . Help please

Hi all

To increase print speed I have connected two fans to the OctoPro board.

I borrowed this code :

Controller fan control

[multi_pin controller_fan_pins]

pins: PD12, PD13

pins: PD12, PD13
[controller_fan control_fan]

Controller fan - FAN2 & FAN3

pin: multi_pin: controller_fan_pins
max_power: 1.0
kick_start_time: 0.5
stepper: extruder

But I get this error :
Klipper reports: ERROR

pin PD12 is an alias for fan_controller_board_pin

Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.
Printer is halted

I am clearly messing with something that could be solved much simpler....

Thanks in advance
Thor

If you want a working example of dual fan for print cooling you can look at my config https://github.com/jscancella/myKlipperFiles/blob/main/vcore3-printer.cfg

So it should be

[multi_pin controller_fan_pins]
pins: fan_controller_board_pin, PD13

[multi_pin controller_fan_pins]
pins: fan_controller_board_pin, PD13

like @blacksmithforlife the multi_pin sections needs to be at the top of the file see: https://discord.com/channels/582187371529764864/843098069200666634/998705565679235132
