I just got a refurbed XFX ti4200 from newegg for $85. However, one of the fins on the fan has completely snapped off and is nowhere to be seen. It sounds just like an unbalanced cetrifuge, or... a lawn mower I guess. My entire case a resonating. I'm thinking about trying to super glue on a beebee where the fin was. The fan is made of some chrome looking metal so I thought that might work. Would a cheap/decent replacement fan be a better idea? Any better repair ideas? thanks
