Average Noise
The PSU’s average noise output is notably low, especially compared to the other SFX units I have tested so far.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The fan’s passive mode is brief, but this is not an issue since the fan starts at low speeds, where noise output remains below 15 dBA. The (dead) low noise operation ends at around 680W, with noise increasing to above 20 dBA. The 30 dBA is passed at around 780W.

At 230V, the fan-stop feature lasts longer, and the 30 dBA mark is passed a bit later than at 115V, at 800W.
