This article covers NZXT Kraken X73 RGB 360 mm.

Overview

The NZXT Kraken X73 RGB 360mm (model RL-KRX73-R1) is a premium all-in-one liquid CPU cooler featuring a 360mm radiator and three AER RGB 2 120mm fans. Its improved pump design delivers efficient heat dissipation while keeping noise levels low at just 21 dBA. Controlled via NZXT CAM software, users can fine-tune pump speed, fan curves, and RGB lighting to match their build aesthetic. This cooler is well-suited for high-end CPUs requiring robust thermal management, including overclocked Core i9 and Ryzen 9 processors. Installation is straightforward thanks to the included mounting kits for both Intel and AMD sockets, making it accessible even for first-time AIO users.

Connectivity & Compatibility

The Kraken X73 supports Intel LGA1700, LGA1200, LGA115x sockets and AMD AM5, AM4 sockets. The included mounting kit covers both platforms with a universal backplate. The 360mm radiator measures 400mm x 123mm x 30mm, so case compatibility is critical — only cases with 360mm radiator support (top or front) can accommodate it. Fans use standard 4-pin PWM headers for speed control, and the RGB lighting connects via the included RGB controller or directly to a 5V ARGB header on the motherboard. Pump power is supplied via SATA, and a USB cable connects to the motherboard for CAM software communication.

Product Info

Released in late 2020, the Kraken X73 RGB sits in the mid-to-high price tier for 360mm AIO coolers, typically retailing around ¥20,000–¥25,000 depending on market conditions. NZXT backs it with a 6-year warranty, reflecting confidence in build quality. The package includes three AER RGB 2 fans, an RGB controller, Intel and AMD mounting hardware, thermal paste, and all necessary screws. Market positioning: it competes directly with other 360mm RGB AIOs like the Corsair iCUE H150i and Cooler Master MasterLiquid ML360, offering a balanced mix of performance, noise, and aesthetics.

Best Use Cases

  • High-end gaming or workstation builds: The 360mm radiator provides ample cooling for CPUs like the Core i9-13900K or Ryzen 9 7950X, keeping temperatures in check during extended gaming sessions or rendering workloads. However, ensure your case has 360mm radiator support before purchasing.
  • RGB-focused custom PCs: With three AER RGB 2 fans and CAM software integration, you can synchronize lighting effects with other NZXT components or use motherboard ARGB headers for broader ecosystem compatibility. Ideal for builders who want a cohesive visual theme.
  • Quiet operation enthusiasts: The pump is designed for low vibration and the fans are rated at 21 dBA, making this cooler nearly silent at idle. Under load, noise remains moderate compared to air coolers of similar performance. Not recommended for ultra-compact cases that cannot fit a 360mm radiator.
  • Long-term reliability seekers: The 6-year warranty and NZXT's reputation for quality ensure peace of mind. The cooler is also serviceable, with replaceable fans and pump, adding to its longevity.
