Average Noise
The average noise is high. Given the restricted fan grille, small PCB, and high output, I didn’t expect great things here.
Fan Noise & Speed Maps @ 28-32 °C
[115V] The unit operates in its passive mode for a small period, and the problem is that at some points, the fan spins fast, even at light loads, to remove the heat. With 280W and more, the fan enters the 30-35 dBA zone, which is pretty high, given that we mainly talk about mid-loads. With 930W and higher loads, noise exceeds 35 dBA; at around 980W, the fan’s noise goes over 40 dBA. If you push the PSU more, you will have a nasty surprise at 1080W with the noise level over 45 dBA.
