I have an XFX 7850, which still works fine, but I believe the fan bearings are shot. I believe it's this model:

The fan starts and stops constantly, and makes a zzzt zzzt zzzt noise, which vibrates the whole PC. When I blow on the fan blades with a can of air it stops immediately after I stop the air.
I think I can replace the fan if I can get a replacement that will fit. I have written to XFX but they have not replied (the card is long past warranty.)
Is there a way I could find a generic replacement fan that will fit my card?
Also, might WD-40 help? Would that be dangerous to the card if it dripped out of the fan?
