Luckily my card was still under warranty so I got a >free replacement from ATI. John: Since posting, I have found the exact replacement! Upon taking the fan out of the heatsink, I found it is an "ADDA" brand, model number AP4505MX-G90 Googled that number, and got a hit for Mouser Electronics! $19.95 w/heatsink. If you need another spare, here it is: http://www.mouser.com/index.cfm?handler=displayproduct&lstdispproductid=347967&e_categoryid=415&e_pcodeid=66402 This must have been divine intervention, since I'm preparing to order some other stuff from Mouser. The fan is now on the list. Meanwhile, while the fan was out, I took the bearing cap off the backside, and put a drop of 3-in-1 oil in there. It's quiet again, but may not last long. Sean
