NZXT Kraken Elite 420 RGB 420mm CPU Liquid Cooler ( Black )

The NZXT Kraken Elite 420 RGB is a 420mm all-in-one CPU liquid cooler designed for enthusiast-grade builds that demand both high thermal performance and striking visual customisation. At the heart of the unit sits NZXT's proprietary Turbine Pump, engineered to deliver a high flow rate combined with strong head pressure, enabling the system to transfer heat effectively from the CPU block to the aluminium radiator under sustained workloads. Mounting the cooler is straightforward thanks to pre-applied thermal paste, tool-free mounting brackets, and a single breakout cable that reduces cable clutter. Compatibility covers a wide range of current-generation sockets: Intel LGA 1851, LGA 1700, LGA 1200, and LGA 115X, as well as AMD AM5 and AM4, so the unit fits the majority of modern desktop platforms without additional hardware. The radiator houses three 140mm fans using Fluid Dynamic Bearings, spinning between 500 and 2,000 RPM (±200 RPM). Each fan is rated to deliver up to 98.61 CFM of airflow at a maximum acoustic level of 34.5 dBA. A Zero RPM Mode allows the fans to stop entirely during light loads, keeping the system silent when cooling demands are low. Fan connections use a 4-pin PWM header for precise speed control. On the aesthetic side, the pump head features a 2.72-inch IPS LCD with a 640×640 resolution and a 60 Hz refresh rate. This display can show custom GIFs, images, real-time system performance metrics, and content from web integrations including Spotify and YouTube. Surrounding the screen is an addressable RGB ring that can be synchronised with other NZXT RGB devices via NZXT CAM software or set to run independent dynamic lighting patterns. The fans themselves are NZXT RGB Core single-frame units, requiring only one connector per fan. Flexible rubber tubing (460mm, CIIR rubber) is reinforced with a polyester PET braided sleeve, providing both handling flexibility and long-term leak resistance.
