Overview

The NZXT Kraken X73 RGB is a 360mm all-in-one liquid cooler designed to address the thermal demands of high-TDP desktop CPUs — processors where a 120mm or 240mm AIO simply cannot maintain safe sustained temperatures under all-core workloads. The three-fan 360mm radiator configuration delivers a meaningfully larger heat exchange surface area than smaller AIO categories, translating directly to lower steady-state CPU temperatures during extended rendering, compilation, or gaming sessions. The three included Aer RGB V2 120mm fans feature a chamfered intake geometry that reduces turbulence at the fan blade leading edge, improving volumetric airflow efficiency — meaning the fans move more air per RPM, which lets them run quieter while still keeping the radiator charged with cool ambient air.

The Kraken X73 RGB is built for enthusiast desktop systems where aesthetics and performance share equal weight in the build brief. CAM V4 software provides the control layer: fan curves, pump speed profiles, RGB lighting synchronization, and real-time temperature telemetry all surface through a single interface. The pump head's rotating infinity mirror design is a signature visual element — functional RGB that doesn't require a separate addressable header or controller box. Nylon-sleeved rubber tubing protects the coolant loop from mechanical damage during installation, which is a realistic concern in cable-dense mid-tower builds. This cooler targets builders who want top-tier thermal headroom, software-driven control, and a unified aesthetic language — and are willing to invest in a 360mm case to get it.

Pros & Cons

👍 Pros

  • 360mm radiator surface area gives the X73 RGB significantly more thermal dissipation capacity than 240mm AIO coolers — critical headroom for high-TDP CPUs under sustained all-core loads
  • Fluid dynamic bearings in the Aer RGB V2 fans provide low operational noise at moderate RPMs, making the cooler acoustically competitive with thicker 280mm alternatives
  • Fine nylon mesh sleeves on the tubing protect against kinking and abrasion during installation, which matters in tight cases with sharp PCIe bracket edges
  • CAM software delivers granular fan curve and pump speed control with real-time temperature monitoring — actual engineering utility, not just RGB management
  • Rotating infinity mirror pump head integrates visual style without adding a separate addressable RGB controller to your motherboard header count

👎 Cons

  • 360mm radiator requires a case with three-fan front or top mounting — verifying fitment is mandatory before purchase, and not all mid-tower cases qualify
  • CAM software has a history of mixed user reviews regarding background resource usage and update reliability — power users who prefer BIOS-only fan control may find the dependency frustrating
  • Aer RGB V2 fans are proprietary to NZXT's ecosystem — if a fan fails out of warranty, direct replacements require purchasing NZXT-specific units rather than generic 120mm alternatives
  • Installation complexity is higher than air coolers, particularly bracket alignment on AMD platforms, which adds time to first-build assembly
  • No onboard temperature display without CAM active — the pump head's monitoring features require the software layer to surface useful data

Frequently Asked Questions

NZXT publishes a compatibility list via their CAM software and product page. The X73 RGB supports Intel LGA115x, LGA1200, LGA1700, and AMD AM4 sockets in its standard bracket set. AM5 compatibility should be verified against NZXT's current support documentation, as bracket availability varies by production run.
The fluid dynamic bearing design in the Aer RGB V2 fans keeps noise low under moderate load — the chamfered intake improves airflow efficiency so the fans don't need to spin as aggressively to move the same volume of air. Full fan curve control is available through NZXT's CAM software, letting you set temperature thresholds against RPM targets to balance thermal headroom against acoustics for your specific workload.
The pump head operates independently of CAM — it will spin up and cool your CPU without software. CAM integration adds full RGB customization and performance monitoring, including temperature telemetry displayed on the pump head. If you prefer not to run CAM, the cooler still delivers its rated thermal performance with default lighting behavior.
A 360mm radiator requires a case with three 120mm fan mounts in a single row — typically front-panel or top-panel mounting. Many mid-tower cases support 360mm radiator mounting, but you must verify your specific case's radiator support specs before purchasing. Full-tower cases universally accommodate the X73 RGB without fitment issues.
