You can do this in ATI tray tools by Ray Adams under the hardware selection. I run two Sapphire 3870's in crossfire mode with fan speed at 100%. I DO NOT use the ATI Catalyst Control Center! You can get ATI Tray tools at http://www.guru3d.com

yes Doc, I use (at times) ATI Tray Tools on my XP partition, but have not converted it to Tray Tools on the Win7RC1 partition yet.....will be doing that when I get time and remember it.....I totally hate the Full Load CCC/Driver package and that is what I currently have on the Win7 partition..
I don't think it is over stressing the vidcard...... heck the 4 120 mm fans and the 240mm top fan along with the Memory heatsink spreaders (that come with this MB type) disipate the heat very well... when loaded heavily using a couple open windows of Autocad 2009 MEP and having internet browser open and some graphic programs open running , with WMP11 blasting out tunes or if I have Reason 4.0 crunching some audio mixing/filtering stuff, my Processor & MB temps are steady under 42deg. C...and my vidcard is around 37 to 38.......
I think it is more a glitch in the Win7/Vista/XP 64 bit drivers currently....... Temps vary roughly 4 to 7 degrees higher on the VC, if I max the vidcard settings out....
will see if the Tray Tools switch helps it any........ got to remember that there is still alot of unavailable 64 bit drivers..... is a tedious constant updating search for new improved drivers & codecs
NOTE to BE - not sure if you missed it, if I max the VC out with ATI Tray Tools in WinXPpro it does not affect it or lose video......if I max the settings out using Win7 RC1 64bit ver with the 9.4 ATI CCC 64 bit drivers, it goes blank screen around 40 or so minutes... but an instant reboot and its right back good again......
backing them down in Win7 to around 2/3rds or 1/2 there are no problems........but I am almost certian it is not a heat issue..........btw my VC fan is manually set to 100%........ ( all fans are manually set to this..........now perhaps and this just popped in my noodle.......you think with all my hardware that I might be losing or might not have enough available power when I max it out in Win7? but why would it not go blank screen in Win XP? hmm........the rest of the pc setup is:
ASUS DVD DL RW Burner with Lightscribe SATA type
ASUS DVD-Rom Drive SATA type
9 in 1 card reader with Floppy drive.....
Dell ULTRA Sharp 19" LCD Monitor
J-S Jazz 902 Subwoofer w/ 4 sat speakers ( using 2 y splitter cables for the sats )
I use my Fluke Laser Temp Reader to shoot instant temps all over the MB, memory, vidcard, processor, N bridge / S. Bridge etc..HD's... to take C & F temp readings....and compare them to what the OSD utility shows....just to see how accurate it is being.usually with in a degree of what it says.....
