Silent Ender 3 electronics fan duct

thingiverse

I was determined not to spend money on new fans for my Ender 3, so I searched Thingiverse for a simple and quiet fan duct that would keep my motherboard cool without breaking the bank. After scouring the site, I couldn't find one that met my standards, so I decided to take matters into my own hands and design one myself. This custom fan duct is engineered to allow air to flow effortlessly while blocking initial noise due to its unique wave pattern. The wave pattern cleverly directs airflow in a way that reduces wind noise significantly. Tip: When using this or any fan duct, remember to remove the iron fan cover, which is often the culprit behind high-pitched noise.
