Hello; I've seen some mention of a configuration file for some of the older ati cards, but did not know if this applies to the 5870? Specifically, I'm trying to create some fan profiles. However, although I can do this on nvidia hardware, the same options do not seem to apply for ati via rivatuner. On my customize button I only have 3 options (Low-level refresh, low-level desktop color, and graphic subsystem diagnostic). Can anyone help me out? I do appreciate your time and effort .
