Description
My cover for installing a much quieter fan on the Creality CR-6 SE power supply.
credit source to Thingiverse 2967389.
adds only 15mm to power supply height...lowest profile of all the remixes
holes will need some enlargement (3mm drill?)
designed for Noctua NF-A9x14 PWM fan...

fan wiring: black=ground, yellow=+12v, blue and green not needed
will need to hack original fan connector to new fan wiring...
new fan is 12v, same as original
requires printer standoffs for proper clearance...I used Thingiverse 4655004 (or 4504419)
(UPDATE: 12/14/20):
I took a second look at the "Low-Noise Adaptor" included with the Noctua fan. As suspected, it's just an inline resistor(about 50 ohms) on the +12v yellow wire. It's supposed to reduce max RPM's from 2200 to 1700. Since the whole point of using this cover is to reduce fan noise, I extracted and installed the resistor into my fan wire harness. I verified that my fan was running before I reassembled my CR6.
Result: I can still hear the p/s fan kick in, but it's even quieter now, and it still cycles on and off, indicating it's doing the job.
NOTE: while I'm sure there is adequate air flow at 1700 RPM for open air use, I might not want to do this resistor mod to a printer that is inside a crazy hot enclosure!
(UPDATE: 07/06/21)
With the power supply quiet, I had modified the the motherboard fan, as well. Recently, I've updated my MB cover with a remix of a cover (Thingiverse 4651648) that I can recommend..(use supports on the fan case)...uses a Noiseblocker BlackSilentFan XR2 60x60x25mm (12v)...with buck converter..
This cover maintains the same low profile obtained with the p/supply cover!
