This bracket mounts the mainboard fan that is currently bolted to the bottom cover directly to the mainboard and adds an additional 4010 fan. You remove 3 mainboard mounting screws and replace with bracket & 3 M3 SHCS. I wanted to be able to cool the MCU when the printer is idle but since the current mainboard fan is controlled with the heatbreak fan, I had to connect a second fan to the extra fan port on the mainboard. This fan can be temperature controlled. You will need root access so as to modify the printer.cfg file.
