NZXT Kraken Z73

Overview

The NZXT Kraken Z73 is an all-in-one (AIO) liquid CPU cooler that integrates a 360mm radiator with a pump and an LCD display on the CPU block. Designed for enthusiasts and high-performance system builders, its primary function is to dissipate heat from central processing units, particularly those operating under heavy loads or overclocked conditions. The cooler utilizes three 120mm AER P fans, which are optimized for static pressure to move air through the radiator fins efficiently NZXT Kraken Z73 product page.

A distinguishing feature of the Kraken Z73 is its 2.36-inch LCD screen embedded in the pump cap. This display can be configured via NZXT's CAM software to show real-time system metrics, such as CPU temperature, GPU temperature, or fan speeds. It also supports custom images and animated GIFs, allowing for aesthetic personalization within a PC build. This feature positions the Kraken Z73 as a component for users prioritizing both thermal performance and visual customization in their systems.

The Kraken Z73 is frequently selected for custom PC builds where thermal headroom for CPU overclocking is a priority. Its 360mm radiator size generally provides more cooling surface area compared to smaller AIOs (e.g., 240mm or 280mm models), contributing to lower operating temperatures for high-end CPUs such as Intel's i9 series or AMD's Ryzen 9 series Tom's Hardware NZXT Kraken Z73 review. The closed-loop design of AIO coolers like the Kraken Z73 simplifies installation compared to custom liquid cooling loops, as it arrives pre-filled and sealed, reducing maintenance requirements.

While NZXT positions the Kraken Z73 for high-performance applications, its aesthetic features also appeal to users creating themed or visually striking PC setups. The CAM software provides granular control over pump speed, fan curves, and the LCD display, allowing users to balance noise levels with cooling performance according to their specific needs. Compatibility extends to modern Intel and AMD sockets, including LGA 1700, LGA 1200, AM5, and AM4, ensuring broad applicability for current-generation CPU platforms NZXT Kraken Series compatibility.

Pricing

The NZXT Kraken Z73 is a hardware product. Pricing varies based on retailer and region. The typical price range for the cooler itself is between $279.99 and $329.99 USD as of May 2026. This pricing does not include any additional installation services or compatible components such as PC cases or CPUs.

Common integrations

The NZXT Kraken Z73 primarily integrates with the following:

• NZXT CAM Software: This proprietary software is essential for controlling the Kraken Z73's fan speeds, pump performance, and customizing the LCD display. It also provides system monitoring capabilities.
• Motherboard Fan Headers: The cooler's fans and pump typically connect to standard CPU fan and AIO pump headers on a motherboard for power and basic control, though CAM software provides more advanced customization.
• USB 2.0 Internal Header: The Kraken Z73 connects to an internal USB 2.0 header on the motherboard for communication with the NZXT CAM software, enabling data transfer for monitoring and display customization.
• Community-driven CAM SDK: While there is no official public SDK for direct hardware control, a community-driven effort exists to reverse-engineer and document the CAM API NZXT CAM API documentation (unofficial). This allows for custom integrations and monitoring solutions beyond the official software.

Alternatives

For users considering alternatives to the NZXT Kraken Z73, several other manufacturers offer high-performance AIO liquid coolers:

• Corsair: Offers a range of iCUE-controlled AIO coolers, such as the Corsair iCUE H150i ELITE LCD XT, which also features an LCD screen and comparable radiator sizes Corsair Liquid CPU Coolers.
• Arctic: Known for its value and performance, the Arctic Liquid Freezer II series provides excellent thermal capabilities, particularly its 360mm and 420mm models, though without an integrated LCD display Arctic Liquid Freezer II 360.
• Lian Li: The Lian Li Galahad II Trinity series offers AIO coolers with customizable RGB lighting and a focus on aesthetic appeal, available in various radiator sizes.
• ASUS ROG: The ASUS ROG Ryujin III 360 is another premium option that includes an LCD screen for system monitoring and customization, often integrated into the ASUS Armoury Crate ecosystem.
• Deepcool: The Deepcool Liquid Cooler LT720 is a 360mm AIO that competes on performance and often offers a more subdued aesthetic compared to LCD-equipped models.

Getting started

Integrating the NZXT Kraken Z73 into a PC build primarily involves physical installation and software configuration. While there isn't a "hello-world" code block in the traditional software development sense, getting started with its core functionality involves the following steps for physical setup and software installation:

# 1. Physical Installation
# Refer to the NZXT Kraken Z73 product manual for detailed steps.
# Manual: https://nzxt.com/support/product-manuals

# Mount the CPU block and pump assembly onto the CPU socket.
# Secure the 360mm radiator to an appropriate fan mounting location in your PC case.
# Install the three AER P 120mm fans onto the radiator.

# 2. Wiring Connections
# Connect the pump's 3-pin power cable to the motherboard's AIO_PUMP or CPU_FAN header.
# Connect the fans to the fan controller cable coming from the pump.
# Connect the USB 2.0 internal cable from the pump to an available USB 2.0 header on your motherboard.
# Connect the SATA power cable from the pump to your power supply.

# 3. Software Installation (Windows Example)
# Download the NZXT CAM software from the official NZXT website.
curl -o NZXT_CAM_Installer.exe https://nzxt.com/cdn/NZXT_CAM_Installer.exe

# Run the installer and follow the on-screen prompts.
start NZXT_CAM_Installer.exe

# After installation, launch NZXT CAM.
# The software should automatically detect the Kraken Z73.

# 4. Configuration within NZXT CAM
# Navigate to the "Cooling" tab to adjust fan curves and pump speed.
# Go to the LCD tab to select display content (e.g., CPU temp, GPU temp, custom image/GIF).
# Ensure firmware is up to date through the "Settings" tab.

For advanced users interested in programmatic interaction, exploring the community-driven NZXT CAM API documentation would be the starting point, though this falls outside standard setup procedures.
