Do modern cards (I'm planning on buying Radeon 9500Pro as soon as it gets available) have any kind of controling their fans, so they would not work if all they do is for example showing windows desktop? My comp works 24h/day, 7d/week, but I really use 3D card only on weekends, so fan rotating all the time would be waste of resources (energy , fan itself) and my nerves (noise, especially during night!). I've put great effort to quiet down my computer, and I wouldn't want to waste that with noisy graphics card cooler...
