Per https://help.prusa3d.com/article/xbuddy-and-loveboard-electronics-wiring-mk4_413095 it looks like you dont have any fan headers, you might be able to repurpose the unused ambient sensor header but no clue sorry. You might try splicing off the part or hotend fan? If you really wanted to use the dc input you might need a voltage step down buck converter or something depending on what your PSU is putting out
You might be able to but you really shouldn't. At the best you wouldn't have control over fan speed. Find the wiring diagram for the board and use a fan header
Oh hey I kinda helped get this started in a very round about way! Nice to see the fluid integration, maybe if I do the mainsail one, someone else will do it a better way lol. I've not been printing much lately but set spoolman up a while ago on the pi running my voron and it's been great.
