Features
Kraken Plus 240mm AIO Liquid Cooler with 1.54" LCD
Smart Cooling. Bold Display.
The Kraken Plus AIO liquid cooler features the custom-designed NZXT Turbine pump and LCD display for efficient, customisable cooling.
Kraken Plus delivers powerful CPU cooling, a fully customisable LCD, and easy installation — designed for builders who want both performance and personalisation.
- High-Performance Cooling: The NZXT Turbine pump is engineered for high flow and head pressure, delivering efficient, low-noise cooling to keep your CPU performing at its best under heavy workloads.
- Custom LCD Screen: Display real-time system temps, animated GIFs, custom images, or web integrations like Spotify and YouTube on a bright 1.54" square LCD — fully customisable through NZXT CAM software.
- Quiet Airflow: High-static pressure fans move air through the radiator to dissipate heat effectively, while Zero RPM Mode stops the fans completely at low loads for silent operation.
- Easy Installation: Pre-applied thermal paste and a single breakout cable from the pump cap speed up installation and reduce cable clutter.
- Wide Compatibility: Includes tool-free mounting brackets that support the latest AMD® and Intel® CPU sockets, including AM5 and LGA 1851.
- Durable and Reliable: Reinforced rubber tubing with nylon-braided sleeving ensures long-term durability and easy routing during installation.
- Optimised Cold Plate: The split-flow copper cold plate channels coolant to the CPU’s hottest areas for better heat transfer, lower temps, and more consistent thermal performance.
- NZXT CAM Software: Use NZXT CAM to monitor temps, customise the LCD display, and control fan and pump speeds — all through an intuitive, easy-to-use interface.
