Noise and Fan Speed (Increased Temperatures)

I am not a fan of the semi-passive operation—the fan-stop feature—because it allows for internal heat build-up, and the fan has to work hard to remove it afterward. In this case, the fan starts at high RPM, and with loads over 750 W, it spins at maximum speed, which produces a lot of fan noise.



Noise and Fan Speed (~30 °C)

The passive operation doesn't last long, and the fan quickly ramps up its speed, entering 25–30 dBA territory. The 30 dBA mark is surpassed at around 610 W load, while 690 W load or more leads to 40–45 dBA noise output, which is high.
