## Long description

The NZXT Kraken Elite 420 RGB is an all-in-one liquid CPU cooler designed for efficient, low-noise cooling with a 420 mm radiator and three 140 mm fans. It uses the custom NZXT Turbine pump and features a 2.72-inch IPS LCD with a 640 × 640 resolution and a dynamic RGB ring for visual customization. The cooler includes extended rubber tubing with braided sleeving, pre-applied thermal paste, and tool-free mounting hardware compatible with modern Intel and AMD sockets.
Advantages
The NZXT Turbine pump improves cooling performance while keeping noise levels low. A high-resolution IPS display and RGB ring offer extensive personalization options and can show GIFs, images or system performance metrics. The cooler is supplied with pre-applied thermal paste and a single breakout cable set for faster installation, and the split-flow cold plate design promotes even coolant distribution for efficient heat transfer. Braided tubing increases durability and reduces handling concerns.
