As expected the fan is extremely loud when spinning with the maximum speed, which resulted in 2890rpm in our testbeds. On some boards the max. power consumption of 3.12W may also cause troubles. Setting the fan-speed to 50% inside the BIOS makes the fan almost inaudible. But at ~1500rpm you are limited to two cores or energy efficient CPUs.
The fan is specified with 35dB(A). We don't have a noise-proof soundbox to test the real noise-level, but our audio-meter showed about 50dB(A) in about 1m distance from the cooler.
