Video card Fan is not working

I just checked today that the "fan" of my video card (ATI Radeon 8500LE 64mb DDR AGP4X) is not working.How to replace the fan? Which kind of fan should I get? I am new to video card fans.


Here are the images of the card (ATI RADEON 8500LE 64MB)..................There are four very small screws around the fan, on the top of the rectangular black part. I don't know whether it is a heat sink of not. But I have found pics of my card over the internet:
I don't know how to add picture so I am including links.
here are the links:

Please tell me if you guys know how to remove this fan................Thank you guys so much for your help...
