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.

Stock Fan Noise

The Sugo SG09's stock fan configuration includes a 180 mm top intake fan and a pair of 120 mm fans, one acting as an exhaust at the rear and other as an intake on the left side, near the front. The three have different acoustic characteristics however.

The top fan is the loudest and produces a low-pitched rumble at 9V and above but smoothes out at 7V and below. At lower speeds we also noted a ticking sound close up. It's equipped with a two speed switch, with the low setting corresponding to somewhere between 5V and 6V. The side fan is quieter and has a very benign sound. The rear fan is quieter still but it has a dry, droney character that is more similar to the top fan than its 120 mm compatriot.

Together, the three fans generate an fairly inoffensive sound with little noticeable tonality.
