240 mm AIO RGB CPU liquid cooler

The NZXT Kraken X53 RL-KRX53-01 is a 240 mm all-in-one liquid cooler built for mainstream Intel and AMD desktop processors. It targets builders who want quiet thermal performance and addressable RGB lighting in a single package. The pump block fits a wide range of sockets including LGA 1700, 1200, 1151 and AMD AM4. Threadripper mounting requires a separate bracket not supplied in the box.

Rotating infinity mirror cap and CAM V4 software

The redesigned pump head uses a 10 % larger infinity mirror ring that can be rotated independently so the logo stays upright whatever the mounting angle. Two Aer P120 120 mm fans with fluid dynamic bearings run from 500 to 2000 RPM and deliver 18.28 to 73.11 CFM at 21 to 36 dBA. CAM V4 software controls fan curves, pump speed and RGB effects through a single USB-linked interface.

400 mm tubing length and socket bracket checklist

The nylon-braided rubber tubes measure 400 mm end to end, so verify the distance from your CPU socket to the planned radiator location before ordering. Intel LGA 1700 systems need an extra mounting bracket that must be requested from the manufacturer. Threadripper sTRX4 and TR4 platforms also require a dedicated bracket that is not included. Ensure your case can accept a 275 mm long radiator with dual 120 mm fan slots.

Questions about this item

How often should the 400mm tubes be checked or the coolant replaced?

The ultra-low evaporation rubber and nylon-braided sleeves are designed to minimise fluid loss, so no routine coolant replacement is required under normal use.

Which component reaches its limit first during a long heavy load — the 2000 RPM fans or the 275mm radiator?

The fans top out at 2000 RPM and 73.11 CFM; beyond that the radiator surface area becomes the bottleneck for additional heat dissipation.

What noise and heat output should I expect when the pump and both 120mm fans run at full speed all day?

At maximum speed the fans produce 36 dBA and move up to 73.11 CFM, while the pump runs continuously at its fixed speed inside the 80mm copper block.
