im have an gfx card evga gt 260 ssc (factory o.c.) i have now testing the temperature this was on the freezing moment by 75?C so i'm setting the fan control to manual. i get now 55-60?C constantly by middle FAN speed..... and the game RUNS!! yeah! and could play multiplayer for more than 1,30 H i think it could be the solve. but game like dead space with full setting and resolution runs without probs... with 75?C temperature.... damned...
CPU Temperature is constantly by 55?C ( Using 2 Threads between 60 - 80% CPU time)
damned the other 2 cores sleeping ...=)
i try it longer and paste my results tomorrow =) but i think the temperature of the GPU it could be the problem =) and an defect temperature auto-control??
