Noise and Fan Speed (Increased Temperatures)
The fan's passive operation lasts too long for a more relaxed fan profile. That having been said, fan noise never exceeds 40 dBA.
Noise and Fan Speed (~30 °C)
Passive mode lasts for a while, and the PSU's noise level sits at around 30–35 dBA with over 600 W load, at operating temperatures close to 30 °C.
