Output Noise
We used a CEM-8852 Sound DB Meter for these measurements, installed 50 cm away from the NAS. Ambient noise in our lab was below 30 dBA while these noise measurements were taken.
The N4310 was very quiet while it operated normally. However, we should stress that Thecus should provide the ability to select or modify the fan's profile through the administration interface. There are currently no such control options, and while the fan is quiet enough, some users would probably still like several fan-control options.
Output Noise Comparison Graphs
The following graphs detail the N4310's output noise and compare it with that of other units we have tested in the past.
The N4310 is among the quietest NAS servers we have tested so far. The low TDP SoC plays a major role when it comes to its noise output since it demands for very little cooling.
