Over the course of the last couple months my video card fan has been getting louder and louder and now is making horrible grinding noises on top of it. I tried blowing out some dust with my air compressor, and there was a bit of dust in there, but it still didn't sound much better and has only gotten worse since then. I figured there might be dust stuck in the bearings but I'm not sure. Regardless, is this anything I should really be worried about? If so, is there a way I can repair it or buy a replacement cooling solution? My card isn't under warranty since it's refurbished so if there is something that needs to be fixed or replaced that falls on me. I'd appreciate any info y'all can give.
