Like me you may be one of those people (idiots) who always install the latest drivers hoping for that little bit of improved performance.
I'd avoid the 196.75 flavour (http://www.engadget.com/2010/03/05/nvidia-pulls-196-75-driver-amid-reports-its-frying-graphics-car/) if I were you.
Nasty.
I thought the fan speed ect was controlled by the card BIOS? Guess not..
Thanks for the heads-up Oldie. :) I usually jump in with both feet.
