JGAurora A5 cold-end 40mm fan adapter

thingiverse

Tired of the ear-piercing shriek from my always-on cold-end fan, I took matters into my own hands and designed a fan duct to replace the stock 30mm fan with a whisper-quiet 40mm Noctua fan - it should fit any 40mm fan perfectly. Since I already had a 12v fan, I needed to use a step-down converter to bring the 24v voltage down to a manageable 12v. Alternatively, you could opt for a 5v fan (Noctua offers one, but it's slightly louder) and plug it into the unused 5v pins instead of the original location. **Warning: The stock screws must be replaced with shorter ones or carefully trimmed to length** **Caution: The metal plate covering the fans requires precise cutting** To ensure a smooth print, I highly recommend printing this design with supports in place. For those who want to make adjustments, I've included the original f3d file for your modification needs.
