The average noise output is on the high side, still notably lower than the Thermaltake GF3 unit and close enough to the NZXT C1200, both using the same platform.
Fan Noise & Speed Maps @ 28-32 °C
The unit operates without its fan spinning at up to 600W loads at 12V, with minimal load on the minor rails, under normal operating temperatures. With a full load on the minor rails, the fan starts to spin at around 550W load at 12V. The 30 dBA mark is passed at 900W at 12V, and with more than 1050W on the same rail, the PSU enters the 40-45 dBA zone. Lastly, with 1130W and higher loads at 12V, noise exceeds 45 dBA.
