Why not just get an aftermarked cooler?
I can't find any for the 5970 that are still available for purchase. If you know of any, do tell!

Why not just get an aftermarked cooler?
Sorry for bumping such an old post, but I wanted to thank the OP for the links to the thermal pads and glue they used. I had 2 5970s die on me after getting clogged with bacon grease (small apartment + paleo diet + open case, should have known 
). When I cleaned them I removed the pads and thought I could just use some thermal paste, but of course it's not thick enough to make contact with the heatsink. I was unsure which pads would be thick enough for this, so thanks for pointing me in the right direction!

Best time to replace the thermal grease on GPU with liquid ultra, dropped temp on my GPU for almost 5c degrees compared with as5 before
This helped me with replacing a fan on a 5870. I ordered the wrong fan and had to cut the tab that holds down the wires. Some epoxy helped. 
All I needed to do was replace one fan. Done and the fan is excellent. Aftermarket cooler probably work well but I was satisfied with the stock fan, plus it was a hell of a lot cheaper.
got all 4 2 days ago, will replace a few tonight.
Why bother with replacing fans and not get an aftermarket cooler ?
Aftermarket cooler :
-much cooler so more OC and stability
-less noisy
-easy to work on if fans die ( unlikely with aftermarket fans ) compared to hassle of stock cooler + fan
Depending on the rig, aftermarket can be better or worse. In open frame rigs they are better, in closed case rigs they are worse. I know of no aftermarket fan that routes the heat of the GPU right outside of the case.
Aftermarket kits are usually much more expensive.
I have reference fans in stock, am located in the USA and take bitcoin as payment.

Here is a link to ebay for the same fan i believe

need one but just ordered 4...ill keep you up to date.
I did a fan replacement today, but I tend to use fans from the GPUs that have previously died. Today it was an XFX card to Sapphire 5970 (the only reason I kept the xfx one was for the fan replacement).
There are some shortcuts once you get all the screws identified. Remember the two little screws above the output connectors, and the four hex bolts. There are something like 34 screws in total to remove (I haven't counted properly.)
I've never had a problem with VRMs and leave the original sticky in place.
For the thermal paste, I did some research on this a year ago and have this tip: use the existing paste, but refresh it with mineral oil. I use tiny amount of spray on CRC (WD40?), mix it with a toothpick or similar and reset the heatsink. I've done this regularly with GPUs and CPUs and it works very well.

Is there a link to US (or eBay) source for this fan yet?
At least the one by your link is proven 
, thanks.
, thanks. 
Damn...you are going to hate me now. I did a search on taobao and found this:
http://item.taobao.com/item.htm?id=10794821928
RMB$16 each.
Thanks for this "not a guide" . I have two 5870 fan failed last week and follow the link buy ten pieces of replacement fans from the link (http://item.taobao.com/item.htm?id=10330120683) provided by OP. Cost me RMB$488 plus RMB$35 shipping(~USD$67). Finished the replacement work last night, now all my rigs are working at full speed

I need a 5870 fan now. :/
The new one looks a little smaller... Also says it uses less amps which means lower rpm... Is there a higher amperage one somewhere? I can't read chinese.
Also have you considered buying a lot and selling them to other miners whos fans have died out on them?

The size is exactly the same (all mounting holes fits as well). Only the specs of the motor/fan is different.
Though I've not checked the rpm difference of before and after. I installed it and it kept the card cool. That's good enough
I really do not want to be a middle man for this, I'm sure that's someone staying in China who can co-ordinate this.
Theres some fans which seem to be the same on ebay, but the markup is outrageous. They want $22 and $30 per fan.
