Average Noise
The average noise output is high!
Fan Noise & Speed Maps @ 28-32 °C
[115V] The passive operation only lasts for a very short period. My best guess for this is the high load on the minor rails. The fan starts at speeds exceeding 800 RPM, with noise output within 25-30 dBA. At 430W, noise exceeds 30 dBA, while at 465W, it exceeds 35 dBA. At 520W, noise goes over 40 dBA, and 660W is in the 45-50 dBA zone. In general, the 750W model should be less noisy than the 850W unit, but this is not the case.
