Noise Level Results
With just the single included 120mm fan spinning at a base speed of very near 1100 RPM, the sound level reported from a foot away from the back of the radiator is 40 dB. While this isn't that loud compared to the stock solution, when compared to other AIOs it is right in the mix with them.
With the fan spinning its heart out for us, we then took another measurement, and found that the Reserator 3 MAX comes in just under the other AIOs with a 57 dB rating. Under all testing conditions we left the head unit's pump running at full speed, and at no time was it ever more audible than the fans and it pretty much not even worth mentioning the slight hum you can hear if the fan is not running to cover it.
We also found that the side orientation of the test system is where the Reserator 3 MAX performed its best, and by a solid degree, but is likely due to the orientation of the radiator and nothing to do with the actual motherboard position.
