Overview

The NZXT Kraken Elite 240 RGB is a 240mm all-in-one liquid cooler that merges high-performance thermal management with a striking visual display. At the heart of the unit is a 2.36-inch LCD screen built into the pump head, offering a 640x640 resolution at 60Hz with 690 cd/m² brightness. Through NZXT's CAM software, this display can show anything from animated GIFs and custom images to real-time system metrics like CPU temperature and clock speeds, turning your cooler into a dynamic centerpiece visible through any tempered glass case panel. The underlying Asetek pump spins at up to 2,800 RPM, providing robust and quiet coolant flow through the 240mm radiator.

Cooling duty is handled by two F120 RGB Core fans equipped with fluid dynamic bearings, delivering a carefully tuned balance of static pressure for pushing air through the radiator and airflow for general case ventilation. The RGB lighting on these fans is fully customizable through CAM, synchronizing with the LCD display and other NZXT components for a cohesive build aesthetic. Installation is streamlined by NZXT's single breakout cable design — one cable runs from the pump head to your motherboard, handling power, data, and fan connections without the tangle of multiple leads. For builders who want their cooling solution to perform as well as it looks, the Kraken Elite 240 RGB delivers on both fronts while keeping noise levels impressively low under typical workloads.

Pros & Cons

👍 Pros

  • Customizable 2.36-inch LCD display adds a unique visual centerpiece to any build with GIFs, metrics, and images.
  • High-performance Asetek pump at 2,800 RPM delivers efficient, quiet coolant circulation.
  • F120 RGB Core fans with fluid dynamic bearings balance strong airflow with vibrant lighting.
  • Single breakout cable design significantly simplifies installation and reduces internal cable clutter.
  • NZXT CAM software provides unified control over display content, fan curves, and RGB lighting.

👎 Cons

  • 240mm radiator provides less cooling surface than 280mm or 360mm options, limiting extreme overclocking headroom.
  • The LCD display and RGB fans increase the price significantly over non-display AIO coolers.
  • NZXT CAM software must remain running in the background to manage display content and fan profiles.
  • The 2.36-inch screen, while sharp, is smaller than the 2.8-inch displays found on some competing elite-tier coolers.
  • Pump head with integrated LCD is bulkier than standard AIO pump heads, which may affect clearance in compact cases.

Frequently Asked Questions

The 2.36-inch LCD supports animated GIFs, static images, real-time PC performance metrics (CPU temp, load, clock speed), currently playing music info, and web content — all configurable through NZXT's CAM software.
The display features a 640x640 resolution with a 60Hz refresh rate and 690 cd/m² brightness, providing a crisp, vivid image that is clearly visible through your case's tempered glass panel.
NZXT simplified the wiring by routing a single breakout cable from the pump head to your motherboard. This reduces cable clutter inside the case compared to coolers that require multiple separate cables for the pump, fans, and display.
The Kraken Elite 240 series supports major Intel and AMD sockets including LGA 1700, LGA 1200, AM5, and AM4. Check NZXT's compatibility list for your specific motherboard socket.
The Asetek pump operates at up to 2,800 RPM and is engineered for quiet operation. Under typical loads, the pump is largely inaudible, with the F120 RGB Core fans being the primary source of any audible noise.
