For some reason, every time I launch SC2, my graphics card fan jumps to 100%, regardless of temperatures. It happens the moment Starcraft 2 launches, and spins down when it closes.

It doesnt seem to be causing any heat problems, and it doesn't appear to be taxing the card too much, but the noise is irritating sometimes.

The computer is running Windows 7, the graphics card is a GTX295.

If you need further detail:

Motherboard: Asus P6T Deluxe
Processor: i7 920
RAM: 9GB
WIth the game running off an SSD that my OS is not installed on.

This is because the card has no graphics to draw.

There is a Dev post from the US here:

Seems you may need to limit your frame rate for now, but this is due to be patched.
