Hi

Do you know if there are official silent fans or generic ones that works well?

To reduce the fan noise level.

There are quieter ones, but you need to remember these are 24VDC fans. Most PC fans that are quieter are 12VDC fans. This means you will have to find a way to convert the 24VDCto 12VDC. A simple 11.5V or 11.7V zener diode in series with the motor should work sufficiently. The work cooling fan isn't very loud, but the hot end cooling fan could be quieter. IF you select a quiet fan that does not cool as well, expect to experience more clogs. Some have chosen to use a larger fan with a custom duct to the smaller size that spins slower and quieter but doesn't sacrifice air volume. The cooling blower for the boards and power supply in the base isn't especially quiet either, but you definitely don't want to sacrifice ventilation there. I believe one would have to get a bit creative to keep temps in check with reduced noise.

That's the problem with moving air, it creates noise. If you thing these are loud, you should hear some that were made a few years back. Our steppers are almost silent, compared to those of a few years back. Sounded like a hydraulic motor.

Hey!

Also looking to reduce the noise from the fans. So I have taken inspiration from this guy:

From the information in this video I have ordered from Amazon:

https://www.amazon.se/gp/product/B07VQCXDTC/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1

And downloaded the printed fan plate from the guys youtube video:

Waiting for the stuff to arrive and will post my result later.

The Ender 6 fan voltage is 24vdc. The Noctua fan is a 12vdc fan. In the video he uses a 24 to 12 voltage converter, which will work fine at 100% and 0%, but not so good at any other percentage. You would do far better to just put a 12v zener diode in series with the fan leads. This will allow the own speed control to work properly.

I bought some 24 vdc fans off of Amazon,

https://www.amazon.ca/gp/product/B07WMMFN2L/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Much quieter than the factory fan, and is the correct fan for the job. No need mess with converting voltages. Best of all, they are very cost effective.

**edit**

I just realized that we are not discussing the work cooling fan, but the hot end cooling fan. Because there is no speed control for this fan, the 24 to 12v converter will work fine for this. A 12v zener will also work just fine.
