System temperatures and noise levels were recorded with SpeedFan and GPU-Z at idle and on load using CPUBurn (K7 setting) and FurMark, an OpenGL benchmarking and stability testing utility.

The stock fans have similar acoustics to those found on the Silencio 550, though they appear to be higher speed models that produce more turbulent noise. The bearings generate a constant, low frequency clicking noise that is audible, but only at close proximity. Otherwise the fans sounded fairly good with a mostly smooth character both at low and high speed. The overall noise level produced by fans was low as well, with the two combining to measure 16~17 dBA@1m at 7V and 25~26 dBA@1m at full speed


At 9V, the front and rear fans generated a noise level of 21 dBA@1m with a generally smooth, broadband character.
