Average Noise
The PSU’s average noise output is low.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The fan’s passive operation lasts for up to 380W at 12V, when the combined load on the minor rails remains below 108W. Even when the fan starts to spin, it does so at low speeds, hence noise output remains below 6 dBA at up to 600W at 12V. After this load level, there are plenty of fan speed modes ranging from 10 dBA to above 35 dBA. The 30 dBA mark is reached around 875W, but it lasts only briefly, with noise exceeding 35 dBA at 900W.

At 230V, the fan speed profile is a bit more relaxed than at 115V.
