Noctua Fan Cover for Silent Mods

thingiverse

I recently bought 2 Noctua A4x20 fans and attached them to a fan duct. However, I didn't like the brown in contrast to the black of the duct. So I designed a cover for the fans and they fit perfectly on the 3rd attempt. They can be easily clipped into the existing holes and also hold up quite well. If it's not enough for you, I've designed a few matching pins that will definitely hold the covers in place. The cover on the right side is designed a little wider for cable routing and also has two approx. 10mm long slots to lead the cable out neatly to the sides if necessary. In addition, the grill prevents you from getting your fingers caught in the fan blades (especially the offspring :-))
