NZXT Kraken X63 280mm AIO Liquid Cooler

Radiator class

Included fans

Pump lighting

Sleeved tubes

280 mm Radiator Cooling

The 280 mm radiator uses 2 140 mm fans to move air through its aluminium fin assembly. The radiator measures 143 × 315 × 30 mm. Check the full radiator and fan clearance against the intended case mounting position, including the space around memory, motherboard heatsinks and the graphics card.

An Adjustable Infinity-Mirror Cap

The RGB infinity-mirror design places lighting above the processor. A rotatable upper cap provides twelve locking positions for the NZXT logo, helping keep the logo aligned when tube routing changes. NZXT CAM configures the compatible lighting, so its appearance can be coordinated with the rest of the build.

Fans Matched to the Selected Version

The Regular option uses Aer P fans; the RGB option uses Aer RGB 2 fans with illuminated rings. Both use 2 140 mm fans for the same radiator class. Choose the version according to the desired fan lighting and cooling arrangement; the fan operating specifications differ between these options.

Pump, Power and Software Connections

The Asetek Gen7 pump operates at 800–2,800 RPM, with the manufacturer specifying a ± 300 RPM tolerance. SATA supplies power, and the internal USB 2.0 cable enables NZXT CAM communication. X-series coolers do not provide built-in fan-speed control; connect fan PWM leads to suitable motherboard fan headers or a separate controller.

Sleeved Tubes and Copper Contact

A copper cold plate transfers processor heat into the liquid-cooling circuit. The 400 mm rubber tubes use a nylon sleeve, providing room to route the assembly between the CPU socket and radiator position. Arrange the tubes without sharp bends and maintain the required component clearance throughout the installed path.
