I have here one of these Arctic Accelero Xtreme 5970 coolers for sale:
http://www.arctic.ac/en/p/cooling/discontinued-products/vga/19/accelero-xtreme-5970.html It does a great job keeping a 5970 cool. Mine ran about 10C cooler on average while mining than it did with the factory cooler, and was nice and quiet too.
These are no longer made by the manufacturer, and are hard to find.
The package says it carries a 6 year warranty.
Includes the heatsink/fan itself, VRM cooler block, instructions, and the retail package. I'm also including a fresh set of thermal pads, so it's essentially ready to install.
