How to fix this fan problem?

[Zacey]

Hello, some of you would be genius at pc work.
Basically my pcs fan out of no where started making a really annoying noise so I have a video here of the sound.

If anyone knows what is wrong with it or how to fix let me know,
Thanks.

The fan has likely come loose or it got knocked out of place somehow. You may find it easier to just buy a new fan, depends on how it's fastened on.

I just tightened and that was the problem, the thing making the noise was the blade hitting the edge. Problem solved thank yous!
