Hi
I love my Bambulab X1 printer, but the sound level has always been horrible, like a jet engine. Now that my warranty ended, I’m willing to do a few mods.
I’m not talking about the noise of the axis. This has been improved a lot with the noise cancelling update for the motors.
I’m talking about the fans. And here is the question: how many are there?
I thought there are four:
- Part fan (in the head)
- Auxiliary fan (on the left side)
- Chamber fan (on the back side)
- Board fan, hidden, you can not control
Therefore, I exchanged the board fan with a Noctua 40x40x20: Bambu Lab MC Control Board Fan Noctua Upgrade by Brody | Download free STL model | Printables.com
This mod worked great, but even when I turn off the part fan, auxiliary fan and chamber fan (0% in the HMI), the X1 sometimes sounds like a jet engine.
Is there any other fan I missed?
