280 mm AIO for Intel and AMD sockets

The NZXT Kraken X63 RL-KRX63-01 is a 280 mm all-in-one liquid cooler designed for mainstream and high-performance desktop CPUs. It supports Intel LGA 1700, 1200, 1151, 1150, 1155, 1156, 1366, 2011, 2011-3 and 2066 sockets as well as AMD AM4 and Threadripper platforms. The pump head features a rotating infinity mirror ring LED that can be reoriented without changing the logo direction. Two 140 mm Aer P fans with fluid dynamic bearings deliver 27.27 to 98.17 CFM at 21 to 38 dBA.

Rotating pump head eases mounting

Installation is simplified by the adjustable pump cap which rotates independently of the housing so the logo stays upright regardless of tube routing. The 400 mm tubing uses ultra-low evaporation rubber with a nylon braided sleeve that resists kinking during handling. A separate LGA 1700 bracket kit is required and must be obtained from the manufacturer. The Threadripper mounting bracket is not included in the box. CAM V4 software provides fan and pump control through a 4-pin PWM connector.

Check radiator space and bracket needs

Verify that your case can accommodate a 315 mm by 143 mm by 30 mm radiator with two 140 mm fan slots before ordering. Confirm the correct Intel or AMD retention hardware is present; the LGA 1700 bracket is not supplied and the Threadripper bracket is sold separately. Ensure the motherboard CPU socket keep-out zone clears the 80 mm by 80 mm by 55 mm pump block. A 4-pin PWM header and a USB 2.0 header are required for full CAM integration.

Questions about this item

How can I confirm the pump is running correctly after installation?

Open NZXT CAM software and verify the pump speed is reported; the pump header connects via USB to the motherboard so CAM reads real-time RPM and coolant temperature.

What mounting hardware is included for Intel LGA 1700 and AMD AM4 sockets?

The box contains brackets and backplates for Intel LGA 1700, 1200, 115x, 2011, 2066 and AMD AM4; a separate Threadripper bracket is required for sTRX4 or TR4 and is not included.

Which radiator size matches a case with 280 mm top clearance?

This model uses a 280 mm radiator measuring 315 x 143 x 30 mm with two 140 mm fans, so it fits cases rated for 280 mm dual-fan mounts.
