Notebook fan?

I accidentally dropped my laptop from my bed. So far nothing happened but the fan is mega loud right now. I've already opened it but don't see anything what can I do?

Uje, uje

Let it cool down. Then find out whether this is a coincidence or a damage.

To do this, start your system after a cold start

and click ctrl + alt + ent

Sort the processes by CPU load. Then you can see who and whether something is the culprit.

It is really due to the laptop, sorted according to CPU load, everything was fine.

Just opening the laptop, I can't see anything that could be broken

This can be the calibration of the fan or the thickness of the thermal paste.
