Hey guys, I've recently purchased a second HD4850 to do crossfire but I have a problem with fan speed. One card runs fine but the other one won't go over 23 percent speed. I have found the fix for this. You have to edit the xml file that has the fan speed data for the profile in catalyst control center.
But the problem is, when I go to that folder to edit the xml....the file isn't there. I have hidden folders showing and I have told windows not to hide system files and it still doesn't show. And I created and extra profile in CCC and it still didn't show up. I even called ATI tech support and they didn't know either. I would really like to get that fan going at 100 percent because my card is hitting 100 C under load. Any help is appreciated.
Yes I know that....that's what I'm doing. It's a glitch in the software that won't let the fan go over 23 percent....you can tell a major difference in the two fans when they are both at 100. If you drag the slider down to 20 percent the fan doesn't spin at all.
