Noise Level Results
With the single fan cooling the CNPS at idle, a mere 30 dB is what gets reported. Adding a couple of fans did raise the noise levels, but that is due to the wire fan mounts and no isolation pads, or I think the 38 dB rating there could have been lower.
The same is found when we overclock the processor. With one fan it is near silent with a 46 dB rating, but when the three fans received 12V to them, the vibration also rose and I got a 59 dB rating with the vibrations and fans combined. Not exactly silent at this point, but it's a performance cooler with three fans, not a silent one.
