Manufacturer description

The NZXT Kraken X63 RGB is an all-in-one CPU liquid cooler for builders who want strong cooling and a pump head that stands out. It ships with NZXT's Aer RGB V2 radiator fans, which use a chamfered intake and fluid dynamic bearings for quiet, durable operation. The pump head gets a redesigned cap with an infinity mirror ring LED that is 10% bigger than the previous generation's, so the RGB looks more vivid through a tempered-glass side panel. The cap also rotates. If your case forces the pump into an unusual position, you can turn the cap so the NZXT logo still sits upright. An added RGB…

Frequently Asked Questions

Can I change the logo orientation if the pump is mounted sideways?

Yes. The Kraken X63 RGB has a rotating infinity mirror cap, so you can turn the NZXT logo to read correctly whichever way the pump head is installed.

What software do I need to control the Kraken X63 RGB?

NZXT CAM. The cooler has full CAM integration, which lets you fine-tune cooling performance and control the RGB lighting effects from one interface.

Are the included radiator fans quiet?

The cooler uses NZXT Aer RGB V2 fans. They have fluid dynamic bearings and a chamfered intake, which NZXT designed for quiet, durable operation with strong cooling. The listing does not give specific decibel figures.

Will the Kraken X63 RGB fit my CPU socket and case?

This listing does not state socket compatibility or radiator dimensions. Check NZXT's official spec sheet for supported sockets and radiator size, then compare that against your case's radiator mounting positions.

How durable is the tubing?

Fine nylon mesh sleeves reinforce the rubber tubing, which adds durability and protects it from mishandling during installation. For warranty coverage, check the product listing or NZXT's support site for current terms.
