Personally i think the an on the 2900 is a mixed bag. When i first insalled it with drivers off the web it did rev up a lot, not really a rev more of a whooshig of air kind of sound. After i uninstalled those i put the driver disc in and installed the whole package on it, that included hdmi audio drivers etc as well, after that the card was very quiet, easily as quiet as my gts is now.
Dunno why it never revved after that, was kind of un-nerving though as i was under the impression the card was sticking to 2d fan speeds so i put back the web drivers soon after and sure enough back to full revs.
