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 Prime95 (large FFTs setting) and FurMark, an OpenGL benchmarking and stability testing utility.

BASELINE NOISE

The PC-V354 shipped with a 14 cm top exhaust fan and two 12 cm LED intake fans. The noise level of the two models were comparable, but the top fan seemed to make more noise as a result of its interaction with the chassis.

12 cm front intake fan.

The top fan had a bit of a rattle at full speed which was alleviated when we pushed down on the corners from the outside. Similarly, at 9V and below it produced an odd fluttery hum that lessened when we pushed down on the hub. The bottom fans suffered from the same symptoms, but to a lesser degree. The way they are partially decoupled from the case seemed to help their acoustics. Thankfully these odd noises are not that noticeable at a distance; they were difficult to distinguish from one meter away.

Together, the fans exceed the 20 dBA level at about 8V. To keep it running quietly we would recommend 6V or 7V at most, but depending on your cooling needs, this might not be possible. Anything less isn't advisable as our sample's top fan would not spin up with less than 6V.


With its stock fans running at 7V, the PC-V354 measured 19 dBA@1m. Interaction between the fans and chassis (particularly the top exhaust fan) generated low frequency tonality centered at ~300 Hz.
