Question Rx 580 nitro+ 4gb weird fan noise and fan not spinning when it is supposed to

[oraopapao]

Hello i have built a pc recently and i notice that on my rx 580 one of the fans is not working and when it tries to spin its making weird noises. I saw a video in which someone cleanes the fans insides and puts grease. I wanted to try it but first im asking for your opinion. Please help!

I also now notice that when i spin the fan its making noise but that doesnt happen when holding the gpu in your hands.
