ANET A8 PSU Fan Mount

thingiverse

This is a compact fan mount designed specifically for mounting a computer fan measuring 92mm square (perimeter) on the side of a power supply unit. To secure it in place, you will need to replace the existing M4 screw on the PSU cover with a longer one. The left peg serves as a stabilizer, holding the fan upright, while the right peg is longer and adjustable to accommodate fans of varying widths. To fasten the fan securely to the mount, I clipped off approximately 2mm from the end of the right peg, heated it up, and used it as a rivet. The fan draws power directly from the 12v rail on the PSU. Note that the indentations on the right side were intentionally made slightly oversized at 0.1mm. By forcing them into place, you can achieve a snug fit without needing to drill additional holes for screws. On the side of the PSU, I applied masking tape to redirect airflow towards the terminals, thereby cooling the rest of the unit.
