This article covers NZXT Kraken Elite 240 RGB v2 Black 簡易水冷CPUクーラー RL-KR24E-B2 FN2382.

Overview

The NZXT Kraken Elite 240 RGB v2 Black is a premium 240mm all-in-one liquid CPU cooler that combines strong thermal performance with a vibrant 2.72-inch IPS display. It supports Intel LGA 1851/1700/1200/115x and AMD AM5/AM4 sockets, making it compatible with the latest Core Ultra 200 and Ryzen 9000 series processors out of the box.
At the heart of the cooler is NZXT's Turbine Pump, engineered for high pressure and high flow to maintain consistent cooling under sustained loads. The two included 120mm FDB fans spin up to 2400 RPM, delivering 75.12 CFM of airflow and 3.3 mmH2O of static pressure — more than enough to push air through the dense radiator fins.
Positioned firmly in the high-end segment, the Kraken Elite 240 RGB v2 is designed for users who value both aesthetics and performance. The IPS display can show real-time system stats or custom GIFs, while the RGB Core fans and pump LED ring sync seamlessly via NZXT CAM software.

Compatibility Guide

Socket support covers Intel LGA 1851, 1700, 1200, 1151, 1150, 1155, 1156 and AMD AM5, AM4. The included mounting hardware works with all these sockets without additional adapters. The pump head measures 93.5mm in diameter and 65mm in height — slightly taller than some competitors, so check clearance in compact cases, especially Mini-ITX builds.
Tubing length is 400mm, which is adequate for most mid-tower and full-tower cases. The radiator dimensions are 120 x 281 x 27mm (W x L x H), fitting standard 240mm radiator mounts. Power is supplied via a single 8-pin PWM/RGB connector, drawing a combined 8.97W (fans 6.72W + pump 2.25W), easily handled by any modern motherboard header.

Product Info

Released in late 2024, the Kraken Elite 240 RGB v2 Black carries a 6-year warranty through NZXT's authorized Japanese distributor. The retail price hovers around ¥20,000, which is typical for a 240mm AIO with an integrated display.
Market positioning is high-end. Within NZXT's own lineup, the Elite series sits above the standard Kraken 240, adding the IPS display and RGB Core fans. Cooling capacity is rated for CPUs up to roughly 200W TDP, making it a solid match for Core i7 and Ryzen 7 processors.

Best Use Cases

  • Aesthetic-focused gaming builders: The 2.72-inch IPS display is the standout feature — show CPU temperature, clock speed, or a custom looping GIF. Combined with RGB Core fans, the entire system lighting can be unified through NZXT CAM.
  • Users cooling Core i7 or Ryzen 7 CPUs: The 240mm radiator handles TDPs around 200W comfortably. Pair it with an Intel Core i7-14700K or AMD Ryzen 7 7800X3D for excellent thermal headroom during gaming and productivity.
  • Noise-sensitive users: The FDB fans are nearly silent at idle and remain quiet under moderate loads. The Turbine Pump also operates with minimal vibration, contributing to a low-noise build.
  • Who should NOT buy: Budget-conscious builders will find better value in the non-Elite Kraken 240 or competing 240mm AIOs without displays. Also, if you plan to cool a Core i9 or Ryzen 9 CPU under sustained all-core loads, consider the 280mm or 360mm versions instead.

Things to Consider

The pump head height of 65mm may interfere with side panels in some cases, especially those with a low CPU socket clearance. Always measure your case's maximum cooler height before purchasing.
For CPUs exceeding 250W TDP (e.g., Core i9-14900K, Ryzen 9 7950X), the 240mm radiator may struggle to keep temperatures in check during prolonged heavy workloads. In such scenarios, stepping up to the Kraken Elite 280 or 360 is advisable.
NZXT CAM software is required to control the display content, RGB lighting, and fan curves. If you prefer hardware-only control or dislike background software, this cooler may not be ideal.

FAQ

Q: Does this cooler work with Intel LGA 1851 (Arrow Lake-S) out of the box?
A: Yes, the included mounting kit supports LGA 1851. No additional adapter is needed.
Q: What can I display on the IPS screen?
A: You can show CPU/GPU temperature, clock speed, load percentage, fan RPM, date/time, or upload custom GIF images and animations via NZXT CAM.
Q: Can I replace the stock fans with other 120mm fans?
A: Yes, standard 25mm-thick 120mm fans are compatible. However, the RGB Core fans use a proprietary 8-pin connector, so RGB control will be separate if you switch to third-party fans.
