Hello! Around a week ago, I rotated my laptop a little to the left and my computer started buzzing like this. Yesterday, I opened it up, cleaned it, made sure everything was back in place properly and started my computer. After that, it didn't make any noise anymore. When using it today, it started doing that again.

I don't see anything that could be hitting the fans. Please tell me there's an easy no cost fix.
