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.

Stock Fan Noise

The Node 605 ships with a pair of 120 mm, 1200 RPM fans, similar to those found in the Define Mini, however we found that the 605's fans generated a greater level of noise. The Mini has the advantage of being a tower case with a door blocking out some of the noise while the 605's fans are directly exposed to the environment.

Baseline Noise Level

30 dBA
24~25 dBA
19~20 dBA
13~14 dBA
Measuring mic positioned 1m at diagonal angle left/top of case.

At full speed the stock fans emitted 30 [email protected], 3~4 dB higher than the Define Mini. Its range was fairly good, dropping down to close to inaudible levels at 5V, which is one of the available settings on the included fan controller. The controller is powered by a 4-pin molex connector and can switch between 5V, 7V, and 12V for up to three 3-pin fans.

While the overall noise level was fairly high for 1200 RPM models, we don't have much to complain about with regards to sound quality. The fans' acoustic profile was almost entirely broadband and neither our mic or our ears picked up any notable tones. They have a very smooth and innocuous sound.
