In terms of performance, well….we could simply leave it at the fact that the H220X is simply the best performing out-of-the-box cooler you can buy today. Period. It slightly betters its predecessor, the H220, as well as the Glacer 240L that is equipped with far more powerful and louder fans. The NZXT X60/61 comes close in terms of performance, but at the expense of far more noise and far less compatibility. 240mm CLCs can’t touch the H220X in all out performance, and at tolerable noise levels the H220X flat out embarrasses them. The Cryorig R1 and Noctua NH-D15 [air coolers] come closest in matching the H220X in terms of performance and noise, but fall short. What more can you say? We put the best out of the box solutions up against the H220X, and the H220X walked away a clear winner and did so with absolutely astonishing performance to noise. With all of this performance the H220X never topped 40 dB at full speed.
