Summary

This fan mount has the least amount of back-pressure for a generally focused fan hood I could come up with for a standard 40mm fan. It is super easy to mount, you will just need to replace the 2 center M3 bolts (35mm length) with 2-M3 bolts of 40mm length. The fan just press fits in. It is a bit tighter if you use ABS because of shrinkage, so you may need to sand.
