There is Fan Show Down on yt where people are trying to beat the original Noctua fan design:<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;playlist?list=PLHLn2U7i45M_EXIsnqUyI-nqCCk-wfCU9" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;playlist?list=PLHLn2U7i45M_EXIsnqUyI...</a>

&gt; To protect our intellectual property, certain features – such as fan  impeller geometries – have been slightly modified while remaining  visually very close to the actual product.<p>Noob question: If someone wants to copy their design with no respect to their intellectual property, can&#x27;t they just 3D scan?

Would have saved me time on a 3D printer I designed a while back. I integrated Noctua fans and ended up measuring mounting dimensions by hand. Having the official CAD models would have made fan integration a lot cleaner.

How much more is the BOM for a silent fan like in Noctua? I recently bought a controller for my well water pump, and it has two 80mm fans for cooling. Sounds like an aircraft when taking off and doesn&#x27;t seem to move much air. I&#x27;m planning to replace them with Noctua fans.

The Fan Showdown YouTube guy is going to have a field day

Mikrotik does this for some of their parts as well
