Stopping Catalyst-Driver to take control from the fan control (HD 5870)

I have successfully flashed my VGA-Bios of my HD 5870 (Sapphire Vapor-X OC). The only changes I made was to pimp the fan control to slow down a little bit.

Everything is OK as long the Catalyst driver is not loaded (DOS, Window default vga driver).

It seems that the Catalyst-Driver takes control from the fan control when loaded.

Is there a way to stop the driver doing this?

For the moment I use MSI Afterburner to control the fan - but it would be nice to do it without third party software.

Thank's a lot.
