Question Case fan not spinning smoothly, rattling

[KevinL123]

Hello, I've had my pc for 2 years now and my case fan started making some rattling noise. I checked at the back to see if it was spinning smoothly, but it was spinning like something was loose. I don't know if I have to oil the inside of the fan or get a new one. If I do oil it, can I use any kind of oil?

PC fans aren't repairable, so you need to replace it.
