Noise Level Results
With 7.5V applied to the pair of fans, we saw via software that they were averaging around 1750 RPM. While we discuss RPMs, for all testing, the pump was allowed to run at full speed and that registers 1785 RPM in the same AIDA64 software.
The pump registers at 31dB, but even at this low voltage, the fans overcame the pump noise as they leveled out to 33dB for our charts. Not too shabby, and nothing really to deal with if in a chassis, but what happens when we let them spool up?
With any cooler, we know one thing, with great thermal results, nine times out of ten, there is also a large amount of audible noise to deal with, and the H105 exaggerates this point. While the chart showed these fans should have spun at near 2700 RPM, ours were only spinning at 2500 RPM, but that is still within the plus or minus 10 percent that these ratings are followed by.
Even slightly slower, we heard a droning hum coming from the cooler as our meter peeked at 68dB. Even louder than the stock cooler, but still close to both solutions that beat it in the thermal charts, so no real shocker here.
