The new NZXT Kraken X40 and X60 CPU coolers attack the fundamental problem we have seen in AIOs with a simple, sensible advance. While others peddle 120mm based units, the NZXT Kraken X40 and X60 are based on 140mm fans and fittings resulting in the most crucial element to liquid cooling; 36% more surface area. More surface area, more heat dissipation, more cooling. It’s that simple. The X40 and X60 also fit more directly into today’s cases which feature 140mm fans predominantly. While most components are shared, the X40 features a 140mm dual fan capable radiator while the X60 packs a huge 280mm four fan capable radiator. One 800~2000rpm FX-140 PWM fin is included with the X40, and two with the X60, each capable of 98.3 CFM.
