The Kraken X52 is twice the cooler the X42 is, with two 120mm fans on its 240mm radiator and should fit in more cases than the 280mm X62.  It is fully RGB'd with a wide gamut of colours to dispaly as well as pulsing and rotating effects if a simple glow doesn't satisfy your cravings.  [H]ard|OCP tested it out on a Core i7-4770K with the fans at full speed as well as the minimum possible speed.  At full speed it was only a hair short of becoming the most effective cooler they've reviewed but did take the loudest noise produced by a cooler handily.  Reducing the speed had an enormous effect on the sound, reducing it to being barely audible but unfortunately the cooling effectiveness also dropped significantly; those who are interested in this cooler should be able to find a happy medium between audibility and cooling performance.  The full review is right here.

"NZXT has been stepping up its cooling game this year, and the Kraken X52 All-In-One represents its "in between" liquid CPU cooler model for those cases with somewhat limited space for the radiator. The Kraken X52 comes with a healthy feature set that has most of the bells and whistles that are needed to make it competitive."
