I really love the high clearance fang mod made by Tacblades.
I really didn't like the high pitched whine that my OEM blower fan made though and that's what lead me to remix this.
This is exactly the same as the original, only this accepts a standard 5015 blower fan instead of the OEM fan in the original.

I'm currently using this fan: https://e3d-online.com/50x50x15mm-12v-dc-side-blow-fan
Note: There is a common 'HK Fan' available everywhere that does not like anything less than 12vdc. This is not good if you plan to run your fan at speeds lower than 100% as the HK Fan will stall if you try to run it at lower speeds.
I used a stainless M3x25 cap-head screw with an M3 nyloc nut and a couple of washers to fix the fan to the fang.
March 2018: I also just uploaded a fan adapter that allows you to fit an additional 5015 blower in place of the 40mm axial fan which I have found to completely eliminate heat creep and clogs related to heat creep: https://www.thingiverse.com/thing:2815752
