Increasing the fan speed of a graphics card will make it run cooler and help to preserve its lifespan. Increasing the speed is also a good idea if you have overclocked the graphics card. Most modern graphics cards can easily have their fan speed manually altered simply by using the updated drivers from either ATI or nVidia, depending on your model of graphics card.
