I ended up doing some experimenting to see how low I can make the fans go without sacrificing print quality and came up with this profile that is significantly quieter. It prints a 22min flawless benchy despite lower fan speeds. Thought I’d share it in case anyone else wants to use it

I have been putting my K1 Max in my laundry room due to the jet-engine/vacuum cleaner sounds it makes when printing. I got annoyed having to move it when doing a load, so decided to try to quiet it down a bit so I can have it nearby in my office.

I used butyl sound dampening sheets on the side panels, but that only helped with vibration noise from the side fans. It helps, but not enough.

  • Speed: 300 mm/s
  • Acceleration: 12,000 mm/s²
  • Max Fan: 40%
  • Chamber Fan: Off
  • Side Fan: 20%

Important: One thing to keep in mind is that if your minimum layer time (in cooling section) is too low your fans will run at 100% when your layers are less than this time, despite what you have fans set at in the profile. If you are printing a smaller model you might get some periods of high fan speed. Just adjust the min layer time for these instances. I have it set to 2 seconds, but 5 should be better for very small prints

    Saving this as I hope to get a K1 Max next week and replace the CR-10 in my home office; didn’t realize they were so loud out of the box!

      That’s funny, I have a CR10 as well!

      but yeah, the K1 and Max are just as loud as Bambu printers. It sounds kind of like someone is vacuuming when its at full blast lol.

      I actually added a second side-fan to my K1 Max using this.

      Overall I think you’ll love the Max, just be sure to shop around for deals. I got mine for $680 instead of $900, don’t pay full MSRP! I think it’s $700 at microcenter right now

      Also, here is my FAST profile that is loud but impressively fast.

        The only Microcenter in my state is 400 miles away but my wife is headed down that way this coming weekend and I’ve already sweet talked her into snagging me one, I’m super excited! Thank you for the profiles, I’m jazzed to see how quickly it can spit stuff out.
