I have had an EVGA GTX 780 for about a month now. In the time I have had it, before and after overclocking it, the card has not gone above 65 degrees Celsius. I have the GPU overclocked to 1.11 GHz, and the RAM clocked at 6.5GHz effective. The over voltage is +38. Even while running Fire Strike or Furmark, the card does not hit anything above 65 degrees. I am worried that the card is throttling itself at a lower temperature than what I specified (85 degrees), because other people seem to have been getting much higher temperatures. The graphics card has EVGA's ACX cooler, and is in a Fractal Design R4. I have 2 Noctua fans on the top, one is blocked by the CPU heatsink, but the other does provide some airflow over the graphics card. AIDA64 is saying that I am reaching my max clock speeds, but I am worried that my performance is still being throttled.
