NZXT Kraken X53 240mm Liquid Cooling System (Open Box) | High‑Performance AIO CPU Cooler

High‑Performance Cooling with NZXT Kraken X53 240mm

The NZXT Kraken X53 240mm liquid cooling system delivers premium thermal performance and customizable RGB lighting for modern gaming and high‑performance desktop builds. This NZXT Kraken X53 240mm AIO cooler features a 240mm radiator with two Aer RGB 2 120 mm fans that balance strong airflow and quiet operation, helping keep CPU temperatures under control during heavy gaming or productivity tasks.

Precision Pump and Enhanced Airflow

The Kraken X53 uses a 7th Gen Asetek pump with speeds from 800 RPM to 2800 RPM, providing efficient coolant circulation and whisper‑quiet performance. The copper cold plate maximizes heat transfer from the CPU, while the reinforced 400 mm tubing and aluminum radiator ensure durability and consistent cooling performance.

Dynamic RGB Lighting and Software Control

Integrated RGB lighting on the pump and fans integrates seamlessly with NZXT CAM software, enabling you to customize lighting effects and performance profiles. The rotatable pump cap lets you align the illuminated logo after installation for a clean, coordinated look.
