What is that noise?

Found out one of the fans was a piece of junk and began to make a loud noise like a car on startup within the first week. Tried to contact manufacturer multiple times. They said they’d send a new fan out me. After weeks with no fan shipped and the fan making noise constantly. I was afraid my system wasn’t cooling properly and that it would overheAt. I have resorted to taking it out and trying to purchase one myself. After the money I spent on this I will be angry if this ruins my system. There are multiple other accounts of faulty fans in cyber power systems.
