like title says, i read all the other post's but i still can't make it work. I think the problem is i'm running xp black as my OS so it's hard for me to locate or even make a xml profile. any help would be greatly appriecated. thanks

btw i'm running crossfire with 2x visiontek 4850's.
 
For Vista

Then go to the following location and open the following file for editing "C:\Users\Your Windows ID\AppData\Local\ATI\ACE\Your CCC Profile.XML. The xml file will have the same name as the Catalyst Profile you saved. right click and hit edit.

For XP

Then go to the following location and open the following file for editing "C:\Documents and Settings\Your Windows ID\Local Settings\Application Data\ATI\ACE\Your CCC Profile.XML. The xml file will have the same name as the Catalyst Profile you saved. right click and hit edit.

Now go down the page until you see the following lines in the XML file ...

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Automatic" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="23" />

Change the "Property name="FanSpeedAlgorithm" value=" from "Automatic" to "Manual"

Then change "Property name="Want" value=" from "23" to your desired fan speed.

Save the file then reload the Profile you just edited in the CCC.

You will have to select the profile every time you re-start the computer. or set it to use that profile eveytime windows boots

Edit:

After experimenting with a build i dids HIS HD 4870 I found a fan-speed of 40% works best for me. My temps went from 79C at idle to 43C

Backed off Fan to 35% and still at only 48C. I'll take it.
