Fans making very annoying sound

[jeppefrostnielsen]

Hi!
I have had some problems over the past 3 days, and I can't really figure out what it is. There is this annoying sound that comes from one of the fans I think, but I don't know which one it is.

My case is a bitfenix nova tg

Sounds like the fan is going bad.... You should always keep them clean... I recommend getting a new fan...

Yeah, I found out that it was the GPU fan.
I have a Gtx 1060 Windforce 6gb, and this problem is very common.
Im trying to RMA it
