Average Noise

The PSU’s average noise output is low at the default settings. You can adjust the fan speed profile to your liking if you connect the PSU to your system through the iCUE application.

Fan Noise & Speed Maps @ 28-32 °C – 115V

The fan’s passive operation lasts for very short periods because of how we apply the loads: first increasing the combined load on the minor rails, then increasing the load on the 12V rail. Nevertheless, the fan’s noise remains below 10 dBA at up to 900W at 12V and with a full load on the minor rails. The 25 dBA mark is reached at 1150W, and noise exceeds 30 dBA at around 1230W. There are some small regions near full load where the fan’s noise is in the 35-40 dBA range.
