How did you wire this in and what firmware did you change?
Just getting into all this board/firmware stuff and trying not to mess everything up :)

I didn't make any firmware changes to support this mod and the only wiring change from stock was I used the Z axis endstop cable for the Y axis and vise versa, due to the Z endstop cable not reaching since the driver board is mounter further from the switch. The 4 fans are powered directly from the main PSU, so they come on when that is on. I used 12 V fans, so I used a buck converter to step down the 24 V from the PSU.

Do they fit on a Ender 3 Pro aswell?

I added versions that should fit the Ender 3 Pro. I have no way of testing them though!

I don't think so, at least with the rear most fans installed. The wider Y axis extrusion would make the Y endstop and stepper motor clash with the position of these fans. I can move the fan mounts an additional 10 mm from the center which should make it work with the Ender 3 Pro with no issues.
