Average Noise
The average noise output is high, considering its capacity. We should also consider though the platform’s not-so-high efficiency, which increases the thermal loads; hence, the cooling fan has to work more to remove the heat.
Fan Noise & Speed Maps @ 28-32 °C
[115V] There is no semi-passive operation, and the fan starts at high speeds, above 1000 RPM, so noise output is within 20-25 dBA from the start. At around 350W at 12V, the 30 dBA mark is passed, and with more than 405W, noise exceeds 35 dBA. Even in the worst-case scenario, noise is within the 35-40 dBA range.
