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 CPUBurn (K7 setting) and FurMark, an OpenGL benchmarking and stability testing utility.

Baseline Noise


An H2 stock fan.

The NZXT H2 ships with three 120 mm fans, one at the rear and two at the front, all the same model except the intake fans have very short cables. The stock fan is an Oreo-style fan with a black housing and nine white blades. The model number on the hub is DF1202512RFLN which correlates to a 1200 RPM 1.92W fan that is used by Silverstone in their original Raven and Fortress series cases.

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


The stock fans on low are very quiet, together measuring 14~15 dBA@1m.

The fans produce a slight hum at higher speeds, but other than that, the acoustic profile is fairly smooth and certainly better than average. They are reasonably quiet when set to medium or low speed using the integral fan controller of the case. Typically front fans measure higher due to how we angle the case, but with the door closed, the noise level was about the same as the rear fan.
