Rear cover fan mod 80 qidi X MAX 3
Rear cover model, to house a 80x10 fan, strategically placed for the cooling of the main processor and the 3 drivers of the electronics.
As the fan is big, take it from low revolutions, it doesn't go over 23db being much more silent and more flow than the standard 40x10.
Two extra holes have been made in the board in case you want to secure the two printed parts, although it is not necessary, they screw on the plastic case without problems.
It is possible to put it on the back of the cover, as well as on the inside, as it is only 10 mm.
I leave image of measures taken directly on the plate, I also leave the original f3d model if you want to adapt or modify to other fans.
