Noise and Fan Speed (Increased Temperatures)
The fan's speed quickly ramps up as the load and the operating temperatures raise.
Noise and Fan Speed (~30°C)
Under normal operating temperatures, the PSU's noise stays low with up to 320 W loads. With more than 390 W, noise exceeds 30 dBA, and with more than 585 W the fan's noise enters the 40-45 dBA zone.
