1 year ago Idk mine is not that loud… I personally run mine on a 5v and have the ground shared with the hotend fan… this allows for it to shut off when the printer is not in use Sent from my iPhoneOn Dec 4, 2022, at 8:48 AM, marsb007 @.***> wrote: The Sunon 20mm fan is extremely loud and annoying. Frankly to the point of being unusable. I've also found it hard to get it to work on the probe pins.

I see that the space is rather tight where the fan currently is, but you could fit a 30mm fan (also easier to source and probably quiter) on the opposite side door/cover (where the Hartk PCB would normally be and where the SB2040 is).
