I'd love to take credit for this, but someone else came up with it. I wouldn't be surprised if the person worked for ATI either as it was his first post. Anyway, I'll cut to the chase. All you need to do is change just two values in the XML which is attached to an ATI Profile you created. I tried this and it worked perfectly, other than the noise generated by 65% fan speed as suggested. I'll experiment later. But it works and easy as anything. I edited his instructions just a hair. See below ....

First Enable Overdrive in the Catalyst Control Center.
Next Create a new Profile using the Profiles Manager in the CCC and make sure Save All Catalyst Control Center Settings is checked.
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 - Thanks Spartan for the path...
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 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. Done.
Edit 1:
After experimenting with my HIS HD4870 I found a fan-speed of 37% works best for me. My temps went from 79C at idle to 48C.
Edit 2:
Contrary to instrcutions posted on Guru3D by Bretware, most people are able to set their fan speed to "Automatic" rather than "Manual". Having it set to "Automatic" should allow the fan speed to ramp-up if needed beyond the fan-speed you entered. This doesn't work for me however and I must use "Manual
