OK, this is a STUPID question, but it may be the one. Did u plug the fan into the ATI's 3 pin conn, or did u plug it into a normal PSU socket. As far as I know the Chrome(? thot it should be Blue) Orb's fan is a 12V one, if you plug it into the Radeon's plug, u may be getting 5V which is unpowering the fan...
