Noise Level Results
At idle with the PWM controlling the fans speed and running just over 6.0V to the fans at this time, I got a reading of 27 dB. I do think that part of the low results seen in the sound testing is due to the fans blowing at the motherboard and a lot of the chop associated with coolers isn't getting to the MIC on my sound meter.
Even with 12V going through both the NF-B9 and Nf-F12 PWM fans, all I could get the meter to read was 48 dB at a foot away from this cooler. Once in a build, especially in an HTPC build, you aren't going to have to listen to the NH-L12 cooling the CPU.
