Didn't have my mobil1 handy but I did have transmission fluid so I put some on the metal pole after popping off the hub and it's running fine again now.  FYI, you can pop the hub off using a plastic pry tool...I used the kind you use on cars, like this http://www.harborfreight.com/5-piece-auto-trim-and-molding-tool-set-67021.html though I used a slightly less cheap one, it really helps with leverage in prying it apart (I tried by hand and it's definitely pretty damned hard to pull off by hand without breaking the fan).

So if you have a buncha car tools and lubricants lying around it should be pretty trivial to fix this without drilling holes in the fan.  I cleaned out the original lubricant first though, it had basically dried out entirely and was more powder than grease.  Not sure if you could get away with using a dry lubricant like molybdenum or something...I actually have a bunch lying around in powdered form (long story), maybe when the other fan goes I'll give it a shot lol.

The bearings are gone. That card is useless unless you get another heatsink/fan. Chalk it up as a loss and learn a lesson. NEVER run a fan over 50% 24/7

I've been running the fan on my 4850 at 100% 24/7 for the last 4 months. Cheesy

EDIT: Holy crap this thread is old.
