AI Verdict
A 240mm AIO with an 8th gen Asetek pump, 3.5” LCD, and an embedded VRM fan, for users prioritizing aesthetics and VRM cooling.
This cooler is a strong contender if you're building a high-performance system where VRM cooling and a customizable aesthetic display are priorities. The 8th gen Asetek pump and embedded VRM fan offer effective cooling, but the premium cost and potential for audible noise from the VRM fan and pump at max speeds mean it's not for everyone.
If a 240mm radiator isn't sufficient for your CPU's thermal demands, consider a 360mm AIO, or if the display isn't a must-have, look for coolers without an LCD to reduce cost.

Pros
- The 8th gen Asetek pump delivers higher flow and lower impedance for cooling performance, with claimed noise reduction.
- A 3.5” LCD display provides instant hardware monitoring and supports customized GIF animations with doubled file volumes (32MB storage, 2000 frames).
- An embedded Axial-tech fan with a new ring-shaped frame design improves airflow to reduce motherboard VRM temperatures by up to 35° Celsius.
- Premium ROG ARGB magnetic daisy-chainable fans simplify installation and cable management, requiring only one cable for both fans.
- Armoury Crate software offers control over pump, embedded fan, and radiator fan speeds, plus custom animations for the LCD screen.
- Includes a free one-year AIDA 64 license for advanced system monitoring.
Cons
- The embedded VRM fan can be noticeably loud at 100% speed, reaching around 50-51 dBA, with a pitch described as annoying.
- Armoury Crate software has segregated fan controls, with motherboard fans managed separately from the pump and VRM fan settings, which can feel overly complex.
- The 3.5” LCD screen's definition is not high-resolution, falling below expectations for graphics quality.
- The pump can be heard over case fans when running at its maximum 3000 RPM.
Dimension Scores
The 8th gen Asetek pump, 30mm thick 240mm radiator, and embedded VRM fan provide strong cooling performance for its size.
While the pump aims for quieter operation, the VRM fan can be loud at 50-51 dBA, and the pump is audible at 3000 RPM.
Constructed with aluminum and copper, featuring a thicker radiator and 400mm reinforced tubing, indicating a robust design.
Magnetic daisy-chainable fans significantly reduce cable clutter, requiring only one cable for both fans.
Best For
- Gaming systems with high-end CPUs that benefit from additional VRM cooling.
- Users who want to display system stats or custom animations directly on their CPU cooler.
- Builders looking for simplified fan cable management due to magnetic daisy-chainable fans.
Not Recommended For
- Budget-conscious PC builders, as this cooler is positioned at a premium price point.
- Users who prioritize absolute silence, especially if running components at full load.
- Those who don't care about RGB lighting or an LCD display, as these features contribute to the cost.
Watch Out For
- The embedded VRM fan, while effective, can be the loudest component in the system at 100% speed, with a reported noise level around 50-51 dBA.
- Armoury Crate's fan control interface is split, managing motherboard fans separately from the pump and VRM fan, which can make unified control less intuitive.
- The 3.5-inch LCD display, while functional, has a lower definition than some users expect, not offering 4K-like graphics quality.
- The pump, when operating at its maximum 3000 RPM, can produce a noticeable sound that is audible over typical case fans.

What Buyers Say
Users frequently highlight the ease of installation, particularly praising the magnetic daisy-chainable fans that simplify cable routing. Many report significant temperature drops on their CPUs, sometimes by 10 degrees or more, even with high-end processors. However, a recurring complaint centers on the noise generated by the embedded VRM fan when it spins up to 100%, with some finding its pitch annoying. The LCD screen, while a popular feature for customization, is noted by some for not having the highest resolution, though it still effectively displays system information and GIFs. The software experience, specifically the segregated fan controls within Armoury Crate, also draws criticism for being less intuitive than desired.
“Look, it cools my i9 like a champ, seriously dropped temps by 10 degrees, and the screen is cool for my GIFs. But man, that little VRM fan can get loud, and the software is a bit clunky with the fan settings. Still, no regrets if you want the looks and the cooling power!”
Common Praise
- Installation is very easy, especially with the magnetic cable attachment system for the fans.
- Provides significant CPU temperature gains, with users reporting drops of 10 degrees or more in idle and under load.
- The embedded Axial-tech fan effectively cools the motherboard VRM area, reducing temperatures.
- The 3.5-inch LCD display is a popular feature for showing system stats and custom GIF animations.
- The overall packaging and finishes are described as impeccable.
Common Complaints
- The embedded VRM fan can be notably loud and annoying when operating at 100% speed.
- Armoury Crate software has segregated fan controls, making it less intuitive to manage all fan speeds from a single menu.
- The LCD screen's definition is not as high as some users expect, impacting graphics quality.
- The pump can be audible over other case fans when running at its maximum 3000 RPM.
Ownership Tips
- The magnetic fan connections are genuinely useful for reducing cable clutter and making fan installation quick.
- You'll likely spend some time tweaking fan curves in Armoury Crate to balance noise and cooling, especially for the VRM fan.
- The LCD screen is a fun novelty, but don't expect a high-definition experience; it's more for system monitoring and simple animations.
- The cooler's performance is strong for a 240mm AIO, but for extreme overclocking on very hot CPUs, a larger 360mm might be necessary.
- The included AIDA64 license is a nice bonus for detailed system monitoring, complementing the cooler's display.

Buying Guide
When you're looking at an AIO liquid CPU cooler like this, you're essentially buying a self-contained cooling system for your processor. It's designed to pull heat away from your CPU more effectively than air coolers, especially for high-performance chips. Pay attention to the radiator size, as a 240mm like this one is a common choice that fits many cases, but larger 360mm options exist for more extreme cooling needs. The pump and fan quality are crucial for both cooling efficiency and noise levels, so look for reputable brands and technologies like Asetek's latest generations.
cooling_method: Fan, Water
This means it uses both liquid (water) to transfer heat from the CPU to a radiator, and fans to dissipate that heat from the radiator into your case. Liquid cooling generally offers better thermal performance than air cooling, especially for powerful CPUs.
fan_size: 240mm
This refers to the size of the radiator, which accommodates two 120mm fans. A larger radiator (like a 360mm) can dissipate more heat, but a 240mm is a popular size that balances cooling performance with compatibility for most PC cases.
Asetek 8th gen Pump
Asetek is a leading manufacturer of AIO pumps. The '8th gen' indicates it's their latest iteration, suggesting improvements in cooling efficiency, flow rate, and potentially noise reduction compared to older generations. This is the heart of your liquid cooling system.
3.5” LCD Display
This is a screen on the pump block that can show real-time system information (like CPU temperature, clock speed) or custom images/GIFs. It's primarily an aesthetic and monitoring feature, letting you personalize your build and keep an eye on crucial stats without extra software windows.
Alternatives
If this cooler doesn't fit your needs, consider a 360mm AIO for increased cooling capacity, or a liquid cooler without an LCD display if you want to save money and don't need the visual customization.
