NZXT showed off its next-generation Kraken X61 and X41 all-in-one liquid CPU coolers. The two feature support for NZXT's CAM monitoring and control software; and are built around the 140 mm fan form-factor. The Kraken X41 features a 140 x 140 mm radiator, with a single included fan; while the Kraken X61 features a 280 x 140 mm radiator, and two 140 mm spinners. Both feature 36 mm-thick radiator flow channels. The included FX140 V2 140 mm spinners are governed by 4-pin PWM headers, and can spin between 800 and 2,000 RPM, pushing up to 106 CFM of air, each. The best part? NZXT is offering a stellar 6-year warranty on the two.
