I replaced the stock fan with Noctua 40mmx40mmx20mm fan.
I made this in thinkercad. This is the first thing i ever made so it isn't perfect but works perfectly. Uses the stock fan mounting hole. Had to cut down stock screw but you can use washers or spacers if you dont want to cut screw.
Feel free to modify or use as you wish.
Hope this helps someone
