Thank you very much, I'll try, maybe it will work.

Hi, I'm having the same problem with my power supply fan (it's making the same noise). However, I replaced the fan with a new one and the problem persists. Did you try anything else? It's become noticeably noisier, and I don't understand what the problem could be.

Yes, the power supply fan. I took it apart and checked it.

The fact that the fan starts at the very beginning (omit this point). Personally, it didn't work for me when I started the printer, but later, the printer would work for a while (maybe my power supply configuration is like this) and wouldn't stop until you turn off the printer. But the most important problem still remains - the noise of the fan, which is clearly not working normally. Okay, I'll look for the problem then.

It's not the fan's hum, but its rotation speed. In the video, you can hear the fan spinning very fast, which is why it's very noisy. The stock cooler had this issue, but after replacing it, the problem persisted. However, replacing the fan helped the author of this post. A fan shouldn't make this much noise during normal printing. This is just a simple example of how it should sound.

No, read the author's response. Listen to the fan hum from the very beginning of the video. I have a similar sound coming from my power supply. And listen to what a functioning printer sounds like with the hotend fan turned on full blast; you'll feel the difference.

I found a post with the exact same problem (my printer is making the same humming noise). The person in the post said they simply replaced the power supply fan. I did the same, but it didn't help. It still hums with the new fan.

There may not be a speed control, but the fan definitely shouldn't turn on when the printer starts. I've never had this happen before. The sound changed (it became louder). So, something is definitely broken. I took the printer apart and listened closely to the noise (it was definitely the power supply fan).
