Output Noise

For these measurements we used a high quality CEM-8852 Sound DB Meter which was installed 50cm away from the NAS. The ambient noise in our lab during noise measurements was close to 30dBA.



During normal operation the noise is low enough for most users, however the max noise the fan can output will be annoying to most. Nevertheless during our tests the fan never worked at full RPMs and to make it work at full speed we had to select the corresponding profile through the web interface.

Output Noise Comparison Graphs

The following graphs show the output noise of TS-419P II in comparison with other units we have tested in the past. Although the TS-469 Pro uses exactly the same fan model and is equipped with a much more powerful CPU, it manages to achieve lower output noise levels in both cases.
