A conversion from 2x 4020 cooling fan to 1x 8010 fan over the mainboard to cool stepper drivers and host CPU heatsink.
To do this mod you have to change the stock heatsinks of the TMC2209 drivers with low profile type, better use copper type because copper has 2x the heat transfer than aluminium.
Material needed:
5pcs 10x14x5mm copper heatsinks (with adhesive tape),
2x M3x12 bolts
2x M3x8 bolts
2x or 4x fan screws
1x 8010 24v fan
You can move the fan plug to PB5 and add this lines to you printer.cfg so the fan will start only when stepper motors move:[controller_fan mcu_fan]pin: PB5fan_speed: 1.0kick_start_time: 0.200stepper: stepper_x, stepper_y, stepper_zheater: heater_bed
