HardwareZone reviews the heat pipe passively cooled AOpen Aeolus PCX6600-DV128LP (GeForce 6600, PCIe) which is the low profile model. See also the Aopen Aeolus PCX6600-DV128LP manufacturer page.
It’s a good review, but it’s more about specifications and gaming benchmarks than the home theater / video playback/accelleration features I’m specifically interested in.
I’m definitely going to have to consider this heat pipe cooled Aeolus Geforce 6600 option to quietly output to my HDTV for my next PVR/HTPC system upgrade
