AI Verdict
This 240mm AIO with a 1.54" 240x240 LCD display and 2800 RPM Asetek pump is for builders prioritizing aesthetics and basic system monitoring over a larger, higher-resolution screen.
This AIO is a situational fit because its 240mm radiator and Asetek pump deliver effective cooling for most desktop CPUs, and the 1.54" LCD display offers unique personalization. However, the reliance on NZXT CAM software for full functionality and the display's limitations compared to higher-end models mean it's not a universal recommendation.
If you need more robust cooling for high-TDP CPUs or a larger, higher-resolution display, look for 360mm AIOs or models with 2.36" IPS LCD screens.

Pros
- The 1.54" LCD display is customizable with GIFs, static images, and real-time PC performance metrics like CPU/GPU temps and RAM load.
- The Asetek pump operates at up to 2,800 RPM, providing effective cooling performance, with one user reporting under 55°C under 4K load.
- Installation is straightforward due to a single breakout cable connecting the pump to the motherboard.
- RGB Core Fans with fluid dynamic bearings offer powerful cooling and vivid RGB lighting, while maintaining quiet operation.
- Pre-applied thermal paste simplifies the setup process.
- NZXT CAM software provides extensive customization for the display and cooling parameters.
Cons
- NZXT CAM software can be buggy; settings sometimes reset on power off, requiring the software to launch for fan and RGB profiles to apply.
- The 1.54" LCD display is smaller and offers less customization than the 2.36" screen found on the Kraken Elite model.
- The TFT 262k LCD (18-bit) screen does not achieve 'true black,' meaning edges can be visible with certain custom images.
- Some users report the CAM software occasionally losing connection to the cooler, leading to uncontrolled fan speeds and noise.
- The RGB fan brightness might not be as high as some users expect.
Dimension Scores
The Asetek pump operates at up to 2,800 RPM, and users report CPU temperatures under 55°C even under 4K load.
The Asetek pump is designed for quiet operation, and the RGB Core Fans use fluid dynamic bearings for optimal airflow with minimal noise.
The cooler features rubber tubing with durable nylon-braided sleeves and a high-performance Asetek pump, suggesting robust construction.
A single breakout cable from the pump to the motherboard simplifies installation and reduces cable clutter.
Best For
- PC builders prioritizing a clean white aesthetic with integrated RGB lighting.
- Users who want to display basic CPU/GPU temperatures or custom static images on their cooler.
- Systems where a 240mm radiator fits comfortably and provides adequate cooling for the CPU.
- Enthusiasts who enjoy customizing their build's appearance through software-controlled lighting and displays.
Not Recommended For
- Users who need a larger, higher-resolution LCD display with more advanced customization options (e.g., video playback).
- Those who prefer to avoid proprietary software for cooler control due to potential bugs or connectivity issues.
- Budget-conscious builders, as the LCD screen adds to the cost without directly improving cooling performance.
Watch Out For
- CAM software settings for RGB and fan curves often revert to default upon PC startup until the software fully loads, leaving fans bright white or at default speeds for several minutes.
- Some users experience the CAM software losing connection to the cooler, causing fans to run at maximum speed and generate significant noise until reconnected.
- The 1.54" LCD display, being a TFT 262k LCD, cannot achieve 'true black,' which can make the screen's edges noticeable when displaying certain content.
- Several users have reported issues with NZXT CAM failing to display GPU temperatures, with no fix available for months.

What Buyers Say
The most surprising finding is the recurring issue with NZXT CAM software, where settings for RGB and fan curves often don't apply until the software fully loads after boot-up, leaving components at default or bright white. Users frequently praise the cooler's ability to keep CPUs cool, with one reporting under 55°C under load. The customizable 1.54" LCD screen is a major draw, allowing for personalized GIFs and system metrics. However, the software's instability, including occasional disconnections and failure to display GPU temps, is a consistent complaint.
“Man, this thing looks sick in my white build, but seriously, why do my fans blast white and my screen stay blank until CAM finally loads up? It's 2024, fix your software, NZXT!”
Common Praise
- CPU temperatures remain low, with one user seeing under 55°C under 4K load.
- The 1.54" LCD display allows for personalized animated GIFs and real-time performance metrics.
- Installation is straightforward due to the single breakout cable design.
- The pump and fans operate quietly during normal use.
- The white aesthetic and RGB lighting are visually appealing.
- NZXT CAM software offers extensive customization options for the display and cooling.
Common Complaints
- NZXT CAM software settings for RGB and fan curves reset on power off and only apply after the software launches.
- The CAM software sometimes loses connection to the cooler, causing fans to run at maximum speed.
- The 1.54" LCD display has less customization and a lower resolution compared to the Kraken Elite's 2.36" screen.
- The TFT 262k LCD screen does not have 'true black,' which can make the screen edges visible.
- Some users report NZXT CAM failing to display GPU temperatures, with no resolution for months.
Ownership Tips
- You'll quickly notice the default fan and RGB settings on boot-up if CAM isn't running immediately.
- The 1.54" screen is cool for basic stats or a small GIF, but don't expect the crispness or size of the Elite model.
- Cable management is genuinely easier than many other AIOs because of the single breakout cable.
- The pre-applied thermal paste is convenient, but some users might still prefer to use their own high-performance paste.
- Be prepared to troubleshoot NZXT CAM if you encounter connectivity issues or incorrect sensor readings.

Buying Guide
When buying an AIO liquid cooler like this, you're looking at two main things: how well it cools your CPU and how it looks inside your PC. The '240mm' refers to the radiator size, which dictates how much heat it can dissipate. The pump is the heart of the system, circulating the coolant, and its RPM affects cooling efficiency and noise. The LCD screen is purely for aesthetics and displaying system info, not performance.
240mm fan size
This refers to the radiator size, which determines the surface area available for heat exchange. A 240mm radiator is a common size, suitable for many mid-range to high-end CPUs, offering a balance between cooling performance and case compatibility. Larger radiators (e.g., 360mm) generally offer better cooling, while smaller ones (e.g., 120mm) are for lower-power CPUs or compact builds.
1.54" square LCD display (240x240 resolution, 30 Hz refresh rate, 300 cd/m² brightness)
This is your customizable screen on the pump. The size and resolution dictate how much detail and clarity you'll get for images or system metrics. A 30 Hz refresh rate is fine for static images or slow-changing metrics, but won't be as smooth as a higher refresh rate for animated content. The 300 cd/m² brightness indicates how bright the screen can get, affecting visibility in a well-lit room.
High-Performance Asetek pump (up to 2,800 RPM)
The pump circulates the liquid coolant through the system. A higher RPM generally means more efficient coolant flow and better heat transfer away from your CPU. Asetek is a well-known manufacturer of AIO pumps, often associated with reliability and performance.
RGB Core Fans with fluid dynamic bearings
These are the fans attached to the radiator. 'RGB' means they light up with customizable colors. 'Fluid dynamic bearings' are a type of fan bearing known for quiet operation and long lifespan compared to sleeve or ball bearings. They push air through the radiator to cool the liquid, so their static pressure and airflow are important for effective cooling.
Alternatives
If this cooler doesn't fit your needs, look for AIOs with larger radiator sizes (e.g., 360mm) for more cooling capacity, or models featuring higher-resolution IPS LCD screens for superior visual quality and customization.
