Kraken Z63 280mm liquid cooler for customizable

The NZXT Kraken Z63 is a 280mm all-in-one liquid cooler designed for builders who want a prominent 2.36" LCD screen on the pump head. It fits Intel sockets from LGA 115x through LGA 1700 and AMD AM4, while Threadripper mounting requires a separate bracket. The package includes two 140mm Aer P fans and 400mm nylon-sleeved tubing.

2.36" LCD screen with 24-bit color and CAM

The defining feature is the pump-mounted display that shows custom images, animated GIFs or real-time system data through NZXT CAM. Orientation can be rotated digitally by 90° for easier viewing after installation. An integrated NZXT RGB connector allows synchronized lighting with other NZXT accessories.

Two 140mm fans rated 21 to 38 dBA at 500 to 1800 RPM

The Aer P fans use chamfered intake and fluid dynamic bearings to move 27.27 to 98.17 CFM across the 315 x 143 x 30 mm aluminum radiator. Noise stays at the lower end during typical desktop loads and rises under sustained CPU stress. The 4-pin connectors enable precise PWM control through the motherboard or CAM software.

Questions about this item

What does the 2.36 inch LCD actually show once the cooler is installed?

The pump head displays custom images, animated GIFs or live CAM system data in 24-bit colour, and the orientation can be rotated digitally by 90 degrees in the software.

How does the 4 pin fan connector limit speed control in practice?

PWM control lets the two 140 mm Aer P fans run between 500 and 1800 RPM, delivering 27.27 to 98.17 CFM at 21 to 38 dBA.

Will the 315 by 143 by 30 mm radiator and 400 mm tubes fit my case and CPU socket?

The radiator needs two 140 mm fan slots, the tubes reach 400 mm, and the block mounts on Intel LGA 1700, 1200, 115x, 2011, 2066, 1366 plus AMD AM4; Threadripper sTRX4 and TR4 require a separate bracket.
