Aerodynamic 60mm to 80mm fan adapter for silent PSU

thingiverse

Works perfectly with noctua 80mm fan. Can't even tell if it's spinning or not. It still cycles on and off, which tells me it's cooling great. I'm using this with a mean well lrs-350, but I think it should work pretty well for all 60mm fans. The screws are a bit tricky to get into the plastic on one side, but once they're in, it's easy to tighten them with the holes I cut out for the allen keys. Also, you can print some plugs to fill in the duct holes. I just pushed mine in by hand and used a lighter to soften the plastic, then smoothed it out with my finger when it was hot. I ran the cable for the fan right through the duct and connected it to the existing fan plug using solder. No voltage conversion or buck converter needed since they were both 12V - check yours though!
