Noise Level Results
With limited volts running through the AF120L fans, Corsair is able to offer the most silent AIO on our charts. A 28dB rating is nothing to laugh at, in fact this goes into the realm of some of the best offerings out there.
When the fans are allowed to run at full blast, the noise level jumps quite a bit, and the H75 loses a couple of spots in the chart. Considering that the noise is just slightly less than the other AIOs on the chart, I am pleased with the findings, but I would have thought it to be more of a jump considering the loss of air flow to get this sort of sound level.
