Power Consumption To emulate real-world usage scenarios, we record mains power draw both when idle and whilst playing Total War: Shogun 2
Temperature To emulate real-world usage scenarios, we record GPU core temperature both when idle and whilst playing Total War: Shogun 2
Noise A PCE-318 noise level meter is placed at front of a Corsair 600T chassis with side panel on to take noise readings when idle and whilst playing Total War: Shogun 2
Overclocking Pushing the graphics card as far as it will go, we increase speeds and re-run the Aliens vs. Predator benchmark
