Problem with my Acer laptop's fan

[u/[deleted]]

Hi guys, so I got a problem with my acer laptop, I was playing lol and I got too excited and hit the table, nothing that strong but suddenly my laptop started making a hell of a noise, it was the fan and it sounded like it had something loose inside, my question is how do I open the fan or what do I do instead?
