Power consumption	To emulate real-world usage scenarios, we record mains power draw both when idle and whilst playing Call of Duty: BO. And, for a worst-case scenario, we throw in numbers from the FurMark stress test.
Temperature	To emulate real-world usage scenarios, we record GPU core temperature both when idle and whilst playing Call of Duty: Black Ops. And, for a worst-case scenario, we throw in numbers from the FurMark stress test.
Noise	A PCE-318 noise level meter is placed at front of a Corsair 700D chassis with side panel on.
