Sapphire HD 7950 FleX Edition

Noise

Noise levels were measured with a decibel meter held about 12 inches away from the cooler. Idle readings were taken with fan speed at 25%, load readings were taken with automatic fan control on while running Furmark, and maximum readings were taken with the fan set manually at 100%. Ambient was taken with the fan not spinning at all.

The two fans on the Dual-X cooler were virtually silent at idle and very tolerable with the card at full load, reaching only 64% fan speed. Turning the fan up to 100% increases noise levels quite a bit but it is still well below any blower style cooler found on most reference cards.

Heat

Maximum temperature was obtained by running Furmark until temps leveled off after a few minutes. The test was then stopped and the system left to sit for about 10 minutes to get the idle reading.

Not only is the Dual-X cooler quiet, it also does an excellent job at keeping this beast cool. With the automatic fan control on, temps reached 73 degrees. With the fan set at 100%, it was able to shave off even more, holding a steady 65.
