Noise Level Results
As you can see, with the increase in fan size and lowering the fans speed, you can get an AIO that performs well and isn't that much of a distraction at idle. It is one of the two quietest solutions for anything in the AIO family, tying with the H220 kit.
Even at load, the noise levels are very acceptable. While 50 dB is definitely audible, even at a bit of a distance, while gaming and the surround turned up, there was much less of it to hear in the room. Again this is the quietest sealed AIO solution on the market, but that does come with a degree or two penalty in the thermal results because of this.
