Average Noise
The PSU’s average noise output is low. This is among the very few times that I see the same average noise output between 115V and 230V.

The fan’s passive mode operates at up to 340W at 12V when the combined load on the minor rails remains below 115W. Even when the fan starts to spin, it does so at low speeds, hence noise output remains below 6 dBA at up to 545W at 12V. After this load level, there are several fan speed modes, ranging from 10 dBA to 25-30 dBA.

At 230V, the fan speed profile is similar to that at 115V.
