how to cool 4850 or 4870

According to bretware, a user needs to follow these simple steps:

1. In Catalyst Control Centre, make sure clock and memory settings are correct and turn on Overdrive
2. Create a Catalyst Control Centre profile called "fanspeed"
3. Navigate to C:\Users\UserName\AppData\Local\ATI\ACE\ and you'll find an XML file titled "fanspeed", open the file in Notepad or your preferred editor. The file should resemble the following:

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Manual" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="65" />
4. As shown above, change the "FanSpeedAlgorithm" value to Manual and the "FanSpeedPercentTarget" value to 65 (or your preferred fan speed in percentage)
5. Save the file and reload the "fanspeed" profile in Catalyst Control Centre.

If you're unable to locate the XML file, you may be required to set your operating system to show hidden/system files.

I did this and brought down my temp. by almost 20c

Pretty much, i suggest like 50 (thats what my 4850 is at, and load it's @ 60C)...
make sure to open it in Notepad, (right click, open with) otherwise it'll come up as readonly

Wow nice! I dont like when it leave 75C in idle and 81C in gaming. Right now it 38C in idle and 42C in gaming, but it sound like jet roar....

Edit: 50 is little quieter than 65.
