It is basically not audible at ~30.6 dB(A) (3400-4600 rpm) in the first 5 minutes. More GPU demanding applications like Unigine Valley take more time to activate the fan. The second run results in the maximum fan speed of 7200 rpm at 39.3 dB(A). You cannot hear the fan for the first ~30 seconds, but the speed will increase to around 6000 rpm and 35 dB(A) until the end of the run. We use the Cinebench R15 Multi test running on macOS. The fan control is seamless, so the results are average values. You can see that the fan quickly reaches its maximum speed of 7200 rpm when you stress the CPU in particular. We will have a look at some scenarios below and start with macOS. However, the fan is only audible at ~2300 rpm in very quiet environments. The fan is even completely deactivated in macOS, while it is always spinning with at least 1200 rpm on Windows (Bootcamp) – independent of the power profile. The good news is that the fan is not audible under light workloads or short peak load (up to ~30 seconds), respectively. However, the high-pitched sound characteristic stays, which is why the fan is not very pleasant under load. One big problem of our previous test model was the rattling fan, but our current model does not have any problems so far.
