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.

Idle system power consumption: 40W AC.

The baseline acoustics for our test system were fairly low thanks in part to our choice of components. The Samurai ZZ CPU cooler was very quiet at 8V, only 16 dBA, and the Coolermaster Silent Pro M700's fan spins very slowly when the load is under 200W.

The included 12 cm and 14 cm LED fans spun at about 1200 and 1000 RPM respectively at full speed. Together they are fairly loud at full speed but thankfully they undervolt very well becoming what we consider to be quiet at between 9V and 7V. Despite their translucent plastic construction, they sounded very smooth throughout their range, though the top fan did develop some tonality especially at higher speeds. While its filter is raised for some breathing room, no such consideration was given to how the fan physically attaches to the case; we wish they had decoupled it like the front fan.


The stock fans at 7V measured ~18 dBA@1m inside the case.
