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


One of the RV05's two stock 18 cm fans.

The Air Penetrator fan features a large hub and a plethora of thin, curved struts on the exhaust side of the frame which channels the airflow into a more controlled cylindrical pattern than traditional designs, and are featured in many of SilverStone's cases. A performance case typically ships with three fans or more but when they measure 18 cm across, just two is more than sufficient. These particular fans are wired with short input headers that connect to the case's fan controllers via 3-pin cables.

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

Using the case's fan controllers, the stock fans ran at average speeds of 680, 980, and 1230 RPM at the three speed settings. Noise levels varied from a modest 23 dBA@1m on low, a loud 34 dBA@1m on medium, and a ridiculous 39~40 dBA@1m on high. As the noise gap between low and medium was sizable, we also tested them at the halfway point using an external fan controller. At 830 RPM, a noise level of 28 dBA@1m was produced.

Fan acoustics were identical to previous samples used in the RV03. The fans have a generally smooth and pleasant character except for some noticeable clicking. This defect has been around since the original Raven, but it's difficult to hear under normal circumstances. Assuming the case is placed on the floor, the fans are far away from the user, the side panels do a decent job of masking the sound, and of course there are other noise-making components in the PC that help drown it out as well.
