Update! Tried the filter it was a bit dirty so I blew it out with an airline but it was the same. So I went for it and took the fan out underneath like the other thread said. I took it apart and blew it out the cleaned it all up and used a little copper grease. I’ve put it back together and tried it lots of times and it seems fine now. No noise coming from it at all. For now at least! 😁
