The fanless Q100 exhibited lower temperatures when idle, despite the fact that the Q110 has a fan which is always on. The fan is fairly active, reacting to any stress to the system almost immediately. The end result is 7~8°C lower load CPU temperatures than the passively cooled Q100. The fan probably could've been made to run slower though, as 60°C is a perfectly acceptable temperature for an Atom processor.

Measured at a diagonal angle to the vertically mounted system at 1m and 0.6m. For the VESA mount, SPL was measured 0.6m directly in front of monitor.

The system generated anywhere between 18 and 34 dBA@1m in direct response to the CPU temperature. The fan speed rarely stayed constant for more than 10~20 seconds at a time. The noise was soft and low when idling or doing simple tasks like surfing the web, whether at 1m or 0.6m distance. As the fan sped up, it generated a hissing type effect, but retained a smooth, broadband profile, and a small degree of whine above 30 dBA@1m. x264 playback, which only results in 50% CPU utilization was enough to push the SPL to 25~26 dBA@1m, a level we don't consider quiet. With full CPU and GPU load, it's unpleasant, especially at the close distance one typically sits from a desktop PC.

Mounting the system behind a LCD monitor did not change its acoustic character, but did lower the overall noise level a great deal, making the system quieter at 0.6m than at 1m with the system out in the open. At 0.6m, the difference was 5 dBA when idle, 8 dBA during x264 playback, and 9 dBA at full load. Subjectively, it brought the noise produced down to a tolerable level. In idle and during video playback, it was fairly benign and low enough to be unobtrusive.
