I am using a stock Gigabyte 6950, not using any overclocking or fan controls. When I play dirt 2 on max, 1920x1080 the temperatures in the ccc have been about 80c. That seems a little high up from my sometimes below 40c idling. Is this safe? I am just really ocd about my components, I know it's not my I7 causing the heat, it usually runs under 40c because of my H70.
