Overview

The NZXT Kraken Plus 240 v2 Black (model RL-KN240-B2) is a 240mm all-in-one liquid CPU cooler from NZXT. The second-generation v2 model brings improved pump performance and quieter fans, delivering more consistent cooling. Its all-black design fits seamlessly into any PC build. Sold and fulfilled by Amazon.co.jp (ASIN: B0F5SGK5Q7).

Key Features

  • 240mm radiator: Fits standard mid-tower cases while providing ample cooling capacity for most CPUs.
  • Quiet fans: The included fans operate at low noise levels, keeping your system silent at idle and quiet under load.
  • Enhanced pump: The v2 pump offers improved reliability and thermal efficiency for long-term stable performance.
  • Universal mounting: Compatible with Intel LGA1700/1200/115x and AMD AM5/AM4 sockets, covering a wide range of CPUs.
  • Simple RGB control: Use NZXT CAM software to customize RGB lighting on the fans and pump head.

Compatibility Guide

  • Socket support: Intel LGA1700/1200/115x, AMD AM5/AM4. Not compatible with older sockets like LGA2066 or TR4.
  • Case clearance: Radiator thickness ~27mm + fan thickness 25mm = ~52mm total. Most mid-tower cases support 240mm radiators on the top or front, but always check your case specifications.
  • Memory clearance: The pump head mounts directly over the CPU socket, so tall memory heatsinks generally won't interfere. However, check clearance with large VRM heatsinks on some motherboards.
  • Power connectors: Fans use 4-pin PWM, pump uses 3-pin (or SATA power). Ensure your motherboard has enough headers.

Ideal Builds

  • Mid-range to high-end CPUs (Core i5/i7, Ryzen 5/7) where quiet cooling is a priority.
  • Builders with glass side panels who want a clean, cohesive look.
  • Users who want to avoid the bulk of a large air cooler that might interfere with RAM or case panels.
  • First-time AIO users (installation is relatively straightforward).

Upgrade Considerations

  • Bottleneck risk: A 240mm radiator may struggle with sustained full load on Core i9 or Ryzen 9 CPUs (especially overclocked). Consider a 280mm or 360mm model for high-TDP chips.
  • Over-spec: For low-power CPUs like Core i3 or Ryzen 3, this cooler is overkill. Invest the savings elsewhere.
  • Upgrade path: When upgrading your CPU later, verify socket compatibility. The v2 covers current mainstream sockets but may not support future ones (e.g., LGA1851).
  • Pump lifespan: AIO pumps typically last 3–5 years. Factor in warranty coverage and eventual replacement when planning a long-term build.
