Modifying the Fan #
Some Creality machines may have a large metal standoff that may not easily fit in the stock holes of some of the 40mm fans that we sell. When the fans were selected they fit the machines we had here to verify compatibility but Creality has changed their shroud design on some machines to have larger holes. This modification will not void your fan warranty.
If you have a machine where the fan is not able to fit over the metal standoffs you can take a pocket knife or deburring tool and carefully round out the side of the holes that face the metal standoffs. You can then use the stock screws and the fan will fit over the larger metal standoffs.
