Average noise development
The average noise level is high. Due to the compact dimensions, the airflow inside the power supply unit is not optimal, so the fan has to work at relatively high speeds. Nevertheless, it is enough for a good middle place
Fan noise and speed measurements @ 28-32 °C
Semi-passive operation lasts up to 600W, with a minimal load on the side rails. The fan noise remains below 30 dBA until the load power reaches 880W. It exceeds 35 dBA at 990W, 40 dBA at 1060W and 45 dBA at 1160W.
