The performance of the card is great. In my opinion, the card is too loud but both under full load and at idle (bearable). But I have designed my other parts of my PC (2xCPU cooler, 5xGehäuselüfter) on Silent mode. But the reference cooler would be too loud to me it was clear in advance, so I have to replace the reference cooler by the Arctic Accelero Mono cooler. It fits exactly on the map. I can not hear the fan hardly out of my body out even under full load. I idle now instead of 36 degrees (reference wave) 25 degrees (Arctic) and under full load now held 76 degrees at 50% fan speed (reference wave) 54 degrees with 32% fan speed (Arctic). The Boost is the original cooler at 1177 MHz and the Arctic at 1240MHz, since the temperature with the cooler Arctic is far below the target temperature of 80 degrees. Overclocked I have the card yet, because it has enough power for my games.
