You could always look for a damaged card and cannibalise that or look for an already disassembled one, Craiglist or Ebay are good hunting grounds (as you know) or you might try ringing round your local stores to see if they can help out.
The part you're linking may work, at least it'll have a working fan but there's not real way to be sure without actually getting it, and at $30.00 plus shipping I'd go for a replacement cooler instead but there is a few points about the Icy Vision:
It's thick, set aside three slots to accommodate it!
The instructions can be a little difficult to follow so proceed carefully.
Some of the parts are very small, I had to use tweezers.
Check the RAM heatsinks will clear the main cooler! Do a 'dry assembly' to check for clearance issues before sticking things down.
Getting the sticky pads to stick to the RAM sinks is easy, but once they're on getting the protective film off the reverse side is a pain, I found the best way was to place the pad a little off centre so I could bend a corner right over backwards using the tip of a craft knife.
Don't forget the VRM cooler!
The fans are not PWM controlled, either connect them to a motherboard header and set the speed through BIOS or use something like the Zalman FanMate controller, otherwise they'll run at full speed all the time-which is a little noisy.
