Silent Ender 3 electronics fan duct
thingiverse
Since I don't want to invest in new fans for my Ender 3, I was searching Thingiverse for a simple and silent fan duct and keep my motherboard cool. I couldn't find one that fitted my expectations, so I designed one. This fan duct is made so that the air can flow easy, but the initial sound is blocked due to the wave pattern. The wave pattern makes the air flow in such a way that 'wind noise' is reduced. Tip: When using this, or any fan duct. Remove the iron fan coverage, which is causing a high pitched noise.
