TESTING

System Configuration:

Measurement and Analysis Tools

System temperatures were recorded with RealTemp, SpeedFan, and GPU-Z at idle and on load using Prime95 (small FFT setting) and FurMark, an OpenGL benchmarking and stability testing utility. Power consumption and noise levels were also measured.

Usually we test cases with a single hard drive but for models designed or marketed for use as a server we also test with three additional drives. The acoustic properties of the drives used are detailed above. Incidentally, the Seagate, Samsung, and WD SE16 drives are the models used for our single drive configuration mini-ITX, microATX, and ATX case systems respectively.

Baseline Noise

The DS380 ships with a trio of Globefan 120 mm 1200 RPM 3-pin fans with a distinct dimple-bladed design inspired by golf balls. It's an older model included in some older SilverStone cases like the Fortress FT02 and Grandia GD05.

The three stock fans combined to produce a loud 34 dBA@1m at full speed but they undervolted well, quieting down to 15~16 dBA@1m at 5V. The fans had a starting voltage in the 4.0V to 4.5V range so 5V is a good lower limit to ensure they spin up properly.

Also keep in mind that the lower noise levels are only possible with all three fans connected if you have some kind of fan control, which the DS380 doesn't offer. As most mini-ITX motherboards are limited to just two fan headers, SilverStone includes a pair of extra headers on the drive cage but they are not controllable.

The Globefan's acoustic character is generally smooth but there is an underlying clickiness that is especially prominent at lower speeds. At higher speeds, the increased turbulence hides this defect well but it's still clearly audible if you get up close to it.
