120mm to 80 / 70 / 60mm PC fan adapters

Some prebuilt computers have large side perforations but only small fan mountpoints. This adapter allows you to easily mount larger fan without a need for case modifications. Although designed to mount 120mm fan into 80mm / 70mm / 60 mm mountpoint, it could be also used other way around.

As it is offset mount, corner hole is shared for mount and fan. This means that for standard length screws only fan or mount can use the corner hole, if you want to have both connected to the corner, you have to use long screw or bolt and nut.
