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

The In Win BUC ships with three 120 mm fans, two UV reactive models at the top and rear with the model number FD1212-S3133E and a current rating of 0.32A; these are the same fans that shipped with the In Win Maelstrom we reviewed a year ago. They are fairly quiet, albeit a bit buzzy at 9V~12V, but mostly smooth at lower speeds. Though the front fan is a translucent blue LED model, it has the same basic design, model number, and power rating as a 1600 RPM version of the Scythe DF series (DFS122512L, 2.2W). The fan's acoustics were similar to the other two.

One odd thing we noticed was the top fan was noticeably louder than the rear one, producing a noticeable clicking sound. We steadied the fan as best we could with no change in acoustics, so it wasn't caused by vibration or interaction with the case.

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

Together the fans emit a total of 29 dBA@1m at full speed, and a very quiet 15 dBA@1m at 5V. Given the space inside the case and ventilation, it's best suited for a gaming system, usually consisting of components which generate a fair amount of noise. As such the stock fans will likely be drowned out below 7V or even 9V depending on the parts used.
