Is anyone having issues with getting their fan speed hack for the 4800 series working? When I create a profile in the catalyst it is not showing up in the following path C:\Documents and Settings\(My profile)\Application Data\ATI\ACE . I am using the 8.6 hotfix drivers and XP. I have reinstalled the drivers a couple times and even tried the 8.7b drivers and the same thing no profile.xml file. Any suggestions?
