Hello, Why is the fan of the power module so loud/making noise from power up (fan 100%?)? That small fan makes a lot of noise as soon as the power switch is turned on. Is there no temperature controlled fan possible? I like to change the fan for a Papst, Zalman or other brand with bigger size bu…

My PSU read 68dB when I got it.

@Edwin Newer to the forum and newer to snapmaker. I voted for the ticket on Trello, but I’d like to know more details. Is there any way that this will be a software/firmware update instead of a hardware upgrade? I’d like to run my machine using octoprint, but the PSU noise is kind of unacceptable …

Well, I just got my Snapmaker after a long wait. Put it together (good instructions, great quality parts). Fired it up and nearly cried. The noise from this thing is disgraceful.

Yes, I needed to swap polarity. It’s easy to tell: hold the new fan connector up to the old fan connector and make sure the red and black wires are in the same position. Mine looked like this when compared side by side: [image]

Hello, there is any problem with a 12V fan that is attached to a 24v pin?
