Windows 7 64-bit w/Bootcamp 3.1: GPU runs much hotter than on Bootcamp 3.0

Question

The graphics chipset driver update between Bootcamp 3.0 and 3.1 has left my graphics card working a lot harder and hotter. Examining (using SpeedFan 4.40) the temperature sensors shows that the graphics chipset never drops below 55c, even during periods of idleness. Additionally, fans are running at an audible level (the usual 2k RPM is not within hearing range).
This behavior did not occur on the Bootcamp 3.0 graphics drivers. Fans rarely ran audibly except during load, and the temperatures were much lower.
I've tried a SMC reset (shfit-ctrl-opt and power button while the laptop is off) with no impact.
Anyone else experiencing this issue, or have any suggestions?

Hello BennB,
Have you checked compatibility?
Just an FYI for you.
It is always best to check with the software manufacturer FIRST. They will tell you if they have tested the product and the version, as well as whether or not it will work with Windows 7.
Check out the Windows 7 Compatibility site: (There you will find out about hardware and software compatibilty.)
http://www.microsoft.com/windows/compatibility/en-us/default.aspx
There is a pulldown from which you can choose "hardware" and "software".
There are also some great articles, instructional videos and such to help with your Windows 7 at our Springboard site:

In any event a lot of the times, Vista drivers will work in lieu of Windows 7 drivers, however, it's not 100%!
As stated previously, it's best to have the Windows 7 certified drivers installed.
Microsoft does have an official Windows 7 Support Forum located here http://tinyurl.com/9fhdl5 . It is supported by product specialists as well as engineers and support teams. You may want to check the threads available there for additional assitance and support.
Thanks again,
