easy guys...  some people just like instructions laid out step by step......

carlo.  it is pretty simple,  just take the thing apart. don't lose the little screws.  put a nice thin layer of thermal paste back on the gpu when you put it back together.  youll be fine.

Remove top stick
Drill a hole in the top off center some
Add oil
Reapply sticker/tape
Thanks SlaveInDebt, Your tips worked,  Cheesy
I wish I had knew this before, (5 getto fan later)

Here's where I've drilled, (pic)
fill that small hole 3-4 time and spin the fan by hand in between.
(I did not have had to remove the heatsin to unplug/pull the wire)
Fan now work like a new.

Also note that my hole is offset from the center,   The first time I had drilled in the middle and ended up into the metal rod/axis.

He is not going to buy them for $40. You can buy them for $10 or so on alibaba in quantities.

These turbine fan have nothing to do with it OP.

We're talking 5850 xtreme fans.

Oh god no don't do this!

The 5800 series fans had quite a few issues.  I think the fan bearings were not properly greased/oiled from the factory.  I followed the above video and my fan is as good as new.  No more noise.

After looking at that video, I am even more likely to drill a hole at the top of turbine fan and pour some oil in there.  I think the trick is to offset it about 2mm.  It save me from having to remove the heatsink to get to the screws.

Thank for the video

That definitely worked!
Hard thing is knowing when to stop drilling.
I drill a bit, use a flash light, rotate the fan to see if anything inside is moving.
If you don't see anything, keep drilling, then repeat.

That fan just broke again a few days ago.  It may be something else, I've put it on a card I am to RMA so won't know it reoiling would fix it again.

Ok.. I'm going to give this a try.

I have 2 failed 5850 Xtreme fans and I don't really want to deal with the RMA process for a discontinued item..

Given SlaveInDebt's success I am going to attempt his method of drilling through the top..


Remove top stick
Drill a hole in the top off center some
Add oil
Reapply sticker/tape

Worked fine, several months since then without issue.

For the people asking how to take one of these apart..

Remove the 3 screws under the fan:




Unplug the power connector:




Push the power cable under the heat sink while pulling on the fan to give yourself some room to work..








Here is the top with the sticker removed:




I'm planning to drill just outside the ring around the center..

Here is the lubricant I'm planning to use:




Does anyone have any last minute suggestions?

I re-oiled several fans already.

I'd suggest that you could use a normal knife, small one, with good tip. Then drill a hole right in the center of the fan,  you will see the metal shaft after several tries.

Thanks for the reply.. good idea..

I wasn't going to use a drill at all..

I have those quick swap drill bits with the hex bases.. I was going to use a 1/16th inch bit and simply spin it in my fingers while pushing down on the end.  That way I can control it better and avoid drilling into something important.

Btw I also want to said that I drill from the bottom, not top. It is quite strange for me to see you remove to top sticker which has "Sapphire" word


If you check the previous pic, you will see that they drilled the bottom, non-moving part of the fan.
