I have an old Gigabyte 8500LE Model:GV-AP64D and its fan has a problem that causes it to be anoyingly loud. Im just using it in a web server. What, if any, Fan could i buy to replace the one on it. The Fan on this card is also part of a very large heat sync that covers the RAM and connects to another heat sync on the back of the card. Any help would be great.
