NZXT RL-KR240-B1 Kraken 240 RGB Liquid Cooler

The NZXT Kraken 240 RGB (RL-KR240-B1) is a 240mm all-in-one liquid cooler that merges strong thermal performance with eye-catching personalization. At its center is a 1.54" square LCD display capable of rendering animated GIFs, static artwork, real-time CPU metrics, and even currently playing music — all managed through NZXT's CAM software. This makes the pump head a functional dashboard and a visual centerpiece in windowed or open-frame builds, rather than just another piece of cooling hardware.

Under the hood, the cooler relies on a proven Asetek pump running at up to 2,800 RPM for efficient, quiet coolant circulation. The included pair of F120 RGB Core fans use fluid dynamic bearings to deliver a balance of static pressure and airflow that keeps the radiator fed while maintaining low acoustic levels. NZXT's single breakout cable design routes power, RGB, and data through one connection from the pump head to the motherboard, cutting down on cable clutter and making the installation noticeably cleaner than competing units that require multiple headers. For builders who want their cooling solution to perform well and look distinctive, the Kraken 240 RGB delivers on both counts.
