Noise and Fan Speed (Increased Temperatures)
The fan speed curve is linear under high operating temperatures, which leads to increased thermal loads. The fan is strong, so don't expect low noise output under harsh conditions.
Noise and Fan Speed (~30 °C)
The PSU's fan exceeds 30 dBA with loads of 400 W or more. At over 600 W, noise output is 40–45 dBA.
