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


One of the GD08's stock fans.

The Grandia GD08 ships with three identical 120 mm, 1200 RPM 3-pin fans, two at the bottom and one at the side near the CPU area. The fans seem to belong to SilverStone's FN series, plain black models with nine blades and curved struts.

Measuring mic positioned 1m at diagonal angle left/front/top of case.

The two bottom fans were noticeably louder than the side fan, producing an extra 4~5 dB at full speed. The difference isn't great enough to justify running them at difference speeds however; Their noise profiles became more similar as the speed lowers. Combined, the set generated a fairly loud 34 dBA@1m at 12V but they undervolted well, with the noise level dropping to just 14~15 dBA@1m at 5V.

The quality of the fans' noise was more than acceptable. At one meter distance, there was an audible humming at full speed but at 9V and below, the fans became increasingly smooth sounding. They did have some minor tonal elements but it was only perceptible close-up with the top cover of the case removed. The overall sound is better than average, regardless of the speed.
