Noise Level Results
For the stock level of testing, the fans slowed to only 1265 RPM. The 31 dB level of noise our meter showed is inaudible to most people, and definitely to those who work around noise all day. When inside of a chassis, there is definitely going to be no noise heard from the fans, unless it is hanging outside the chassis in the back; even then it's a maybe.
While it looks like the SkyWater and its 41 dB rating has slid into the fifth spot, I look at it from a completely different angle. Not to say that fifth place is not something to be proud of on its own, but look again, as this is the best solution over all other versions of sealed or unsealed water cooling solutions.
While this level is slightly audible, and may be slightly distracting to those with sensitive ears, you can do much, much worse in this department.
