60mm Wanhao Duplicator 6 motherboard fan holder

thingiverse

I needed a fan that would cool the Wanhao Duplicator 6 motherboard more quietly than the existing 4010 axial fan, while providing equal or better cooling without having to raise the printer or remove the bottom cover panel. This solution was achieved. Note that it requires a 6010 or 6015 axial fan, as a 25mm fan is far too thick. However, if you prefer using a 25mm fan and are willing to leave the bottom cover panel off, I have also included an STL file for a 5mm M3 spacer, allowing you to print multiple spacers and raise the mount for clearance around the fan. You will need four 35mm or 40mm long M3 screws to attach it to the motherboard mounts; I bought mine from Amazon. I am not providing a link as availability changes frequently and it is easier to search for the style and quantity you want. Additionally, you will require a quiet 6010 fan. I chose this one: https://smile.amazon.com/gp/product/B01FBPQLKG/. It is sufficient for my needs (~24dB @ 3000RPM @ 12cfm), considering that the original fan manages only 9cfm at 34dB. This model features sleeve bearings, so if you find a dual ball bearing fan with similar specifications, please let me know.
