OK hello peeps.
First of all this morning my XFX RADEON HD6870 the fan started acting up(sounded like a dried out fan bearing) and when i took out the fan peeled away the circle sticker there was no RUBBER PLUG i was like eek.gif

TUTORIAL ON HOW I SOLVED THE NOISE PROBLEM

TOOLS NEEDED

I used the HDD magnet to magnetize the screwdriver because i did not want any screws falling back inside of the card , that would of bin a headache if one of those screws got caught between the heat sink fins.

REMOVING THE MOUNTING SCREWS

NOTE u don't have to take apart the whole video card just to get to the fan. HERE IS ALL THE MOUNTING SCREWS for removing the fan
just keep turning the fan blade to clear the screw heads so u can get to them


FAN IS REMOVED

I took the surgical blade and just nicked the edge of the sticker peeled it off and i was shocked to see NO RUBBER PLUG

There was this HARD PLASTIC BACKING cover looking thing


Then i took the SURGICAL BLADE and create a starting point for the drill bit because i did not want the bit to go sliding all over the place.
SO while carefully drilling this was the result, I got to see the the SHAFT, I then dropped some oil inside and finger spun the blade for the oil to penetrate into the bearings


LAST THING to do was cleaned out the excess oil,place back the sticker installed back the fan with the 3 screws ''BE CARE FULL NOT TO STRIP THE THREADS'' and then ur all finished!!

This just saved me, thank you! My 6850's fan had all but stopped moving entirely, and the people at my computer store were telling me either to get a whole new gpu, or some ridiculously huge, expensive heat sink/fan combo that would've barely fit in my case. I'd taken the whole thing apart, but I was just kinda afraid to jab into the back of the fan and end up /having/ to buy new parts.. After seeing this, I knifed into the back of the thing with no worries, and now my fan is happier than I can remember it being in the past half-year. I can play games again for more than 20 minutes at a time, hooray! biggrin.gif

I do not want to revive a dead thread but im currently experiecing the same issue.

Before my fan completetly stopped it was malfunctioning. The temp reading for my GPU were high and when i tried to force the fan to spin manually i noticed some resistance. I am planning in trying this out but im unsecure of what exactly to do in the last part. How will this help the fan to respond again and pretty much fix my GPU.

I have another plan in case this one seems to be too complicated or not helping. It is purchasing a case fan and make it blow directly to the GPU.

I hope anyone can clear my doubts and help me out with this one. I already submitted a warranty report but no responses so far.

I had my fan make some loud noises last week. Luckily it was gone after I had cleaned it with compressed air. But will probably need this fix in the future tongue.gif
