These fan mounts tip the fans by 10 degrees for 2 purposes: 1 direct the cold air towards the mother board, 2 show off both sides of the LEDs for a more uniform look with the AIO.
Everything was sized for the Lian Li O11 Dynamic Evo case and their SL Fans. but likely would work for others. I used extra thru bolts from the AIO to go all the way thru the fan instead of the grub screws.
PS: Special shout out to Lian Li for sharing the CAD models of their cases!
The author marked this model as their own original creation.
