Why is my laptop making weird fan noise?

So the laptop keeps making this weird noice like its hitting something, and the laptop notices the problem and it shuts the fan off, after that i just shut the laptop off. 2 Weeks later i tried turning it back on but then it does this, i cant remember but it makes this "update" or a "reboot" thing like a automatic troubleshoot thing where it tries to fix it

I dont know this was 2 months ago
