60mm to 40mm PSU fan adapter

thingiverse

I wanted to replace the noisy 60mm fan from the printer PSU with a Noctua fan, but the 60mm was out of stockt so I bought the Noctua NF-A4x10 FLX fan which is 40mm 12v. The 60mm to 40mm fan adapters I found here were not of my liking so I created one on Thinkercad, I had to cut the PSU fan grill but that was easy (used some pliers and sanded) then used the noise reduction and the 3pin to 2pin cable adapters included with the Noctua fan and installed it. You will need the following to do the proper install: 4 x M3x16 screws (or longer, preferably not longer than 24mm) 4 x M3 nuts (any M3 nut will do) 2 x M4x8 screws (or 4 if you use the squared version) 2 x M4 nuts (or 4 if you use the squared version) 1 x 40mm 12 volt fan (preferably noctua as these are silent, great quality and come with all the adapters needed). PSU uses 12volt fan, DO NOT try a 5 volt fan. I created 2 versions, one squared with 4 mounting screw holes for the PSU and a rounded one with only 2 screw holes which I liked more. I used the noise reduction cable adapter from Noctua with the 3pin to 2pin adapter and I can't hear at all the fan, the PSU does stay cool enough without risk of overheat and looks cool. You can print it rotated with the 40 mm fan side up without supports. Takes about 30 to 40 minutes, depending on the speed, I printed it at 50mm/s.
