Review: NVIDIA GeForce GTX 680

To observe the noise levels produced by the various solutions, we put the cards in a Cooler Master RC-690 II Advanced casing and measured noise at idle and in load. We used an SSD and all the fans in the casing, as well as the CPU fan, were turned off for the reading. The sonometer was placed 60 cm from the closed casing and ambient noise was measured at +/- 21 dBA. Note that for all the noise and heat readings, we used the real reference design of the Radeon HD 7950, rather than the press card supplied by AMD.
The GeForce GTX 680 is quite quiet at idle and less noisy in load than the GeForce GTX 580 or the Radeon HD 7970. Note however that the fan speed varies slightly but constantly, giving variable noise levels from 43.5 to 45.2 dBA.
Still in the same casing, we took a reading of the GPU temperature with the internal sensor:
The GeForce GTX 680 cooling system is pretty effective.
