Rattling fan noise


So I’m running Fedora 39 on my Framework 12th Intel i7 1260p but it really doesn’t seem like a Linux issue. My laptop fan makes a rattling noise like it is hitting something but I don’t see what. I tried to take a look at my fan but saw nothing wrong. Maybe its vibrating? Weirdly enough, it seems to make more noise when it is at low speed (> 0 RPM though) than if it is at high speed. It also makes that noise when i tilt the laptop.

Seems like for now after tightening a bit more the fan its gone…

Out of curiosity, as I have been experiencing similar issues, which part did you tighten?
