Quiet operation clearly isn’t one of the GT70 0NC’s strengths. During BluRay playback, the system isn’t intrusively loud and shouldn’t have a negative effect upon your viewing experience. When the heat is turned up and extra load is applied, the fan starts to ramp up to a far more audible speed. When operating at full fan speed, the system is loud – there’s no denying it!
