Temperatures

GTX 580 Beast 2 card runs 101MHz faster than reference GPUs, but we measured quite good thermals. Operating temperature was up to 64°C. Perhaps you expected lower GPU thermals but you should know that we used a single fan radiator with room temperature at 25°C.

Overclocking

We didn’t manage to break 1GHz for the GPU but we played games for about half an hour at 970MHz.
