Ortur Obsidian Noctua Fan Support

thingiverse

Ortur Obsidian is a very good printer for cheap However the fans are very noisy. I have started by changing the fan extruder by a Noctua to try, and the difference is so big that I decided to replace the second fan. But for this one, it's necessary to change the radial fan by a axial fan I have designed and adapter So this is the result This adapter uses the original fan duct designed by Ortur Because the Ortur supply the fans with 24 v dc, I have to use a DC/DC converter to have 12V I have also designed a support for the cables and DC converters I have set the Dc convert to 10v because the volume of air flow is enough, but it's possible to use the adapter cable delivered with Noctua fan to reduce speed Note: speed will be constant and not automatically adjusted by the printer after this I also use inserts to screw the fan An example of what I bought : https://www.amazon.fr/ARCELI-MP1584EN-Puissance-abaisseur-Convertisseur/dp/B07MY2XP21/ref=sr_1_1?__mk_fr_FR=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=2C5X440VJG4D7&keywords=ARCELI+5+Pcs+MP1584EN+Ultra+Petit+DC-DC+3A&qid=1652384770&sprefix=arceli+5+pcs+mp1584en+ultra+petit+dc-dc+3a+%2Caps%2C43&sr=8-1 https://www.amazon.fr/ruthex-Insert-filet%C3%A9-100-pi%C3%A8ces/dp/B08BCRZZS3/ref=sr_1_1?__mk_fr_FR=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=1MXKYIER4CSDL&keywords=3d+ruthex+M3+insert+filet%C3%A9+%7C+100+pi%C3%A8ces+RX-M3x5%2C7&qid=1652384725&sprefix=3d+ruthex+m3+insert+filet%C3%A9+100+pi%C3%A8ces+rx-m3x5%2C7%2Caps%2C44&sr=8-1
