Corsair CX-M Series 450 W Review - Ideal for Small PCs
Cross Load Tests »Noise and Fan Speed (Increased Temperatures)
The unit's fan spins at low speeds with light loads, so it won't bother you. As expected, the fan has to spin fast at high loads and temperatures to cool the thermal load.
Noise and Fan Speed (~30°C)
There is no passive operation, but I don't mind as long as noise output is low under light and medium loads. With more than 255 W load, the PSU breaks the 30 dBA mark; with more than 290 W, it exceeds 35 dBA.
