I don't like their noise test because they're using two different types of fans and I would guess that Noctua's fans are better than Corsair's fans, which could've easily lead to the small difference in temps, and you do that same as I would do: switch the fans out for something better (Gentle Typhoon, EK Vardar, Noctua, etc.). However, my personal recommendation for AIOs is when you've got the space to install a 240/280/360mm setup, since I don't feel that 120mm AIOs are all that useful, other than for simpler cable routing.
