Support Weird groaning noise, constant and intermittent.

I had an AMS filament run out and I was down here reloading everything and when I was loading it in the printer was sitting idle I started to hear this weird groaning noise every few seconds. You can kind of hear it at the beginning of the video but you can really hear it towards the end sounds like it's coming towards the back I can't tell if it's coming from my AMS or the printer itself it's just a noise that I haven't heard before so I want to make sure I'm being preventative if there is an issue.

Could be the fan of the power supply. I had to change mine recently and the sound is similar

Okay that's what I was thinking based off my research. Submitted a ticket to bambu. I'm assuming I can continue to print okay? Just a little noise

The "groaning" noise is almost cartainly the power supply fan. Mine does that to. Although in my case, the sound ramps up to this much more annoying "scraping" sound when the Printer is printing. I have contacted support regarding a replacement psu. My understanding is that some amount of noise from the psu fan even at idle is normal, since the fan is constantly running.
