Im running an Evga 7600GS in my HTPC with the K8NGM2-FID. It has a passive cooler on it. Its in a really cramped case without alot of airflow and it stays cool enough. If you dont like that idea, and you dont care about the pci-e slot above the x16 slot, you can try the Thermalright V-1 ultra. Im not positive that it will allow you to use the pci slot below the video card though.
