When it comes to cooling, the performance is simply staggering, but at the same time it’s about what I would expect from a massive 420mm AIO as they can handle extreme TDP with ease. The sheer surface area of the radiator, paired with three of the best consumer fans on the market, makes light work of any processor you throw at it. I personally run a 420mm with an undervolted CPU and Noctua fans, and even while gaming it’s virtually silent, and just the best way to game in my opinion.
