AI Verdict
This 240mm aluminum AIO cooler with a 7th Gen Asetek pump and ARGB fans is for Intel LGA1700/115x/2066 and AMD AM4/TR4 builds needing RGB aesthetics.
This AIO is a strong contender if you're already invested in the ASUS ROG ecosystem and value synchronized ARGB lighting. Its 7th Gen Asetek pump and ROG-designed fans provide effective cooling for a 240mm unit. However, recurring pump noise and persistent Armoury Crate software problems mean you need to be prepared for potential troubleshooting.
If you need more consistent quiet operation or more reliable RGB software, look for AIOs from brands with a stronger reputation for software stability or those using different pump designs.

Dimension Scores
The 7th Gen Asetek pump and ROG-designed fans provide 81 CFM airflow and 5.0 mmH2O static pressure, delivering effective cooling for a 240mm AIO.
While the Asetek pump starts at 840 rpm for low noise, many users report noticeable buzzing, whining, or crackling from the pump, particularly at 100% speed.
It features reinforced, sleeved tubing for increased durability and a copper cooling plate with micro-channels for thermal resistance.
The 380mm tubing length offers flexibility for routing, but the multiple cables for fans, pump, and RGB still require careful management within a build.
Best For
- PC builders prioritizing ARGB lighting synchronization with an ASUS ROG motherboard.
- Users with Intel LGA1700 or AMD AM4/TR4 CPUs requiring liquid cooling for performance.
- Enthusiasts who want a closed-loop AIO system with minimal maintenance compared to custom loops.
Not Recommended For
- Users who prioritize absolute silence, as pump noise can be an issue.
- Anyone unwilling to troubleshoot software issues with RGB control (Armoury Crate).
- Builders on a strict budget, given its entry-plus price band.
Watch Out For
- The pump often makes a buzzing or whining noise at 100% speed, which some users found loud enough to return the unit.
- Armoury Crate software frequently fails to detect the cooler or control its RGB, with users reporting issues like the RGB not turning off during sleep mode.
- The plastic backplate for mounting can be fragile; one user reported screws coming out when tightened, unlike a metal alternative.
- Some users experience crackling noises from the pump, which can be loud enough to be compared to 'rats in walls'.

What Buyers Say
The most surprising finding is the consistent complaints about pump noise, with users describing buzzing and crackling sounds even from new units, leading some to return the product. Beyond the noise, the Armoury Crate software is a frequent source of frustration, often failing to detect the cooler or control its ARGB lighting, sometimes not even turning off during sleep mode. Installation is generally straightforward, but one user highlighted a flimsy plastic backplate that stripped easily. Despite these issues, the cooler is acknowledged for its cooling performance and aesthetic appeal when the RGB works as intended.
“Man, this thing cools my CPU like a champ, but the pump sounds like a tiny angry bee in my case, and Armoury Crate is a total headache to get the lights working right, I just want my RGB to match, is that too much to ask?!”
Common Praise
- Effective CPU temperature reduction.
- Aesthetic appeal of the ARGB lighting and ROG design.
- Relatively easy installation process.
- Compatibility with a wide range of Intel and AMD sockets.
Common Complaints
- Noticeable pump noise, including buzzing, whining, or crackling, especially at 100% RPM.
- Armoury Crate software frequently fails to detect the cooler or control RGB lighting.
- RGB lighting on the pump block does not turn off during computer sleep mode.
- Plastic backplate for mounting can be problematic, with screws coming out if overtightened.
Ownership Tips
- Pump noise can become more apparent over time or at specific RPMs, requiring manual adjustment of pump speed curves.
- Expect to spend time troubleshooting or reinstalling Armoury Crate to maintain RGB control and device detection.
- The RGB on the pump might stay lit even when the PC is in sleep mode, which can be distracting.
- Ensure careful tightening during installation, especially with the plastic backplate, to avoid stripping screws.

Buying Guide
When you're looking at an AIO cooler like this, you need to think about two main things: how well it cools and how much noise it makes. A 240mm radiator is a common size, offering a balance between cooling capacity and case compatibility. The pump and fans are the primary components affecting both performance and acoustics. Also, if you care about RGB, the software that controls it is a big deal.
Seventh Gen Asetek pump
Asetek is a major manufacturer of AIO pumps, and their 7th Gen is known for its efficiency and starting at low RPMs for quieter operation. This means the core of the cooler is built on a proven design.
2x 120mm 4-pin PWM Addressable RGB Radiator Fans
PWM (Pulse Width Modulation) fans allow your motherboard to precisely control their speed, spinning them faster when your CPU is hot and slower when it's cool, balancing performance and noise. 'Addressable RGB' means each LED can be controlled individually for more complex lighting effects.
240mm Radiator
This refers to the size of the heat exchanger. A 240mm radiator (which holds two 120mm fans) is a popular choice for mid-range to high-end CPUs, offering better cooling than smaller AIOs or air coolers, but requiring enough space in your PC case.
Alternatives
If you need quieter operation, look for AIOs with larger radiators (280mm or 360mm) or those from brands with a reputation for silent pumps. If software stability is a top priority, research user feedback on RGB control applications from other manufacturers.
