TESTING

System Configuration:

Measurement and Analysis Tools

System temperatures and noise levels were recorded with SpeedFan and GPU-Z at idle and on load using Prime95 (large FFTs setting) and FurMark, an OpenGL benchmarking and stability testing utility.

Baseline Noise

The included 18 cm fan is a higher speed model than those found in the Silverstone Raven series and Fortress FT02 and unfortunately exhibits the same clicky bearing. At higher speeds it is not as noticeable, but at low speeds it is audible even at one meter's distance. This is less of an issue in the larger Silverstone cases because the fans are encapsulated inside the case. The SG07 is more likely to be placed closer to your person, and the fan is located right at the very top. Aside from the clickiness, the fan is very quiet at 5V. At 7V it develops a bit of a hum but is bearable. At 9V and above, it becomes unreasonably loud and has a drone that strengthens as the fan speed increases.

The power supply on the other hand is virtually inaudible at low power levels, measuring just 13~14 dBA@1m.

Idle system power consumption: 41W AC.

With the system idling, the CPU fan at a modest 8V, and the 18 cm fan at 5V, the SG07 is fairly quiet, measuring 17~18 dBA; the CPU fan helps mask the ticking system fan somewhat giving it a more broadband profile..


The SG07 with its stock fan on low measured ~19 dBA@1m.
