Noise Level Results
When I gathered the 34dB result for the stock runs, I was monitoring the speeds, and with 1055 RPM, this is the result I saw on the meter. Not too shabby considering that this is really just a barely audible hum at this level.
When we moved over to the overclocked runs and allowed the motherboard to deliver 12V to the pair of fans, I could easily hear them from across the office. With the fans now showing 1603 RPM in AIDA64, I took out the meter and saw the 58dB reading, shown in the chart above.
