Acoustic recordings are taken while the system sits at the desktop under minimum load. Then we run 3DMark’s FireStrike 1.1 and take the measurements again once the sound has settled to its maximum. All fans were left to the ASUS-supplied defaults. We recorded audio from a 1m distance from the base unit at approximately the same level.
You can hear the fans spin up a little under load, but 48dB is not noisy compared to some of the 17in gaming monsters we’ve tested in the past. You might not want to play games at a Benedictine monastery on this notebook, but in any other environment it won’t be any disturbance at all.
