Power, temps and noise
Power consumption, while high for a single card, is a fraction better than other overclocked GTX 780s.
Gainward's fan-control is programmed such that the GPU is allowed to run at up to 80°C when gaming. Not going for an aggressive (read low) temperature should mean the three fans remain fairly quiet.
And yup, it's hardly audible in our test system. We reckon Gainward has made a good compromise between noise and temperature.
