I had a similar issue years ago with a 6800 Ultra. Getting more air to the video card brought down my temps and the problem disappeared. Yours is an old card, makes me wonder how long it's been since you cleaned the dust and junk out of the heat sink and fan. Dust is a great insulator and will clog heat sinks and fans and render them nearly useless. If you use compressed air to clean, make sure you do not allow the fan to spin as it will generate an electric current that can back-feed to the power supply and motherboard and do some serious damage.
