Average Noise
At 230V, the average noise output should be lower, but this is not the case, as you can see in the graphs above. In general, this is not a quiet operating high-capacity unit.
Fan Noise & Speed Maps @ 28-32 °C
[115V] The passive operating doesn’t last long using a load pattern that fully stresses the minor rails. The problem is that once the fan starts to spin, it quickly increases speed, outputting higher than 25 dBA noise. At 700W, the 30 dBA mark is passed, and at 880W, the PSU’s fan is above 35 dBA. Lastly, with more than 1025W, the noise goes over 40 dBA. The PSU’s fan speed profile could be improved, especially at light loads. Moreover, a less restrictive fan grille would help.
