Pros
- Gen S Dual Chamber Pump with a redesigned copper base targets heat spots and increases water flow for enhanced cooling performance.
- Includes CryoFuze thermal paste with a 14W/mK thermal conductivity rating, maintaining stability from -50°C to 250°C.
- Optimized PWM curve fan blades deliver 71.93 CFM airflow and 1.86 mmH2O air pressure.
- Compatible with a wide range of Intel (LGA 1150, 1151, 1155, 1156, 1200, 1700) and AMD (FM2, AM2, AM2+, AM3, AM3+, AM4, AM5) sockets.
- The pump has a 70,000-hour MTTF, indicating extended operational lifespan.
- Features a clean, minimalist design on the pump cover and frosted fan blades for enhanced ARGB lighting dispersion.
Cons
- Fans can become audible at 75% RPM and 'rowdy' at 100% RPM, reaching 27.2 dBA.
- The 3-pin connector for the pump limits direct speed control compared to 4-pin PWM options.
- Radiator dimensions of 10.91" height, 4.71" width, and 1.07" depth may present fitment challenges in smaller cases.
Dimension Scores
The Gen S Dual Chamber Pump and 14W/mK CryoFuze thermal paste provide effective heat transfer, with users reporting lower CPU and GPU temps.
The pump operates at a quiet 12 dBA, but fans can reach 27.2 dBA at max RPM, becoming audibly 'rowdy' above 75% speed.
The aluminum radiator has a sand-blasted finish, and fans include rubberized corners, contributing to a premium feel.
The fan system uses a two-split PWM header and a 3-in-1 daisy chain system for RGB, which simplifies some connections but still requires routing.
Best For
- Gaming PCs requiring efficient CPU temperature management for CPUs like Ryzen 7 9700x.
- Users building systems with ARGB lighting ecosystems wanting customizable illumination.
- Enthusiasts seeking a liquid cooling solution for a wide range of Intel and AMD platforms.
Not Recommended For
- Silence-focused builds where fan noise above 50% RPM is unacceptable.
- Compact ITX cases with limited space for a 240mm radiator and associated tubing.
Watch Out For
- Fans can reach 27.2 dBA at maximum 1750 RPM, which users describe as 'rowdy' at 75-100% speed.
- While installation is generally straightforward, the daisy-chaining for RGB might require careful cable routing.
- The pump uses a 3-pin connector, which means motherboard control over pump speed might be limited to voltage adjustments, not precise PWM.

What Buyers Say
Users frequently highlight the effective cooling performance, noting it keeps CPUs like the Ryzen 7 9700x at low temperatures. The sand-blasted finish on the radiator and the polished pump head give it a premium appearance. However, the fans can get loud when operating at higher RPMs, with some users describing them as 'rowdy' above 75% speed. Installation is generally straightforward, especially for AMD sockets which reuse existing motherboard mounts.
“This thing actually keeps my 7900X from melting, but man, those fans really start screaming when I'm pushing it hard, like a jet engine taking off.”
Common Praise
- Maintains low CPU temperatures, even under load.
- Radiator has a sand-blasted finish that feels premium.
- Pump head features a polished face plate.
- Fans include rubberizing in all corners.
- Installation is straightforward, especially for AMD AM4/AM5 sockets.
Common Complaints
- Fans become audibly loud at 75% RPM and 'rowdy' at 100% RPM.
- The 3-pin pump connector offers less precise speed control than 4-pin PWM.
- RGB daisy-chaining, while functional, can add to cable clutter if not managed carefully.
Ownership Tips
- The included CryoFuze thermal paste is effective and doesn't dry out quickly.
- The ARGB lighting on the fans diffuses well, providing a consistent glow.
- The pump's dual-chamber design seems to move water efficiently, even at lower RPMs.
- The mounting hardware for Intel sockets is comprehensive, while AMD uses existing backplates.

Buying Guide
When you're looking at an AIO liquid cooler, you're essentially getting a self-contained water cooling loop for your CPU. This means better heat dissipation than air coolers, especially for higher-end processors. You need to consider the radiator size (240mm in this case) to ensure it fits your PC case, and the fan noise levels, as these can vary significantly. Also, check the CPU socket compatibility to make sure it works with your motherboard.
Radiator Size (240mm)
This refers to the length of the radiator, which determines how much surface area is available to dissipate heat. A 240mm radiator, with two 120mm fans, is a common size that balances cooling performance with case compatibility for many mid-range to high-end CPUs.
Gen S Dual Chamber Pump
This isn't just marketing; a dual-chamber pump separates the cold and hot liquid paths, which can improve efficiency and longevity by preventing hot liquid from mixing with the pump's motor. The 'Gen S' indicates an improved design for better flow and pressure.
CryoFuze Thermal Paste (14W/mK)
Thermal paste fills microscopic gaps between your CPU and the cooler's coldplate, allowing for efficient heat transfer. A thermal conductivity of 14W/mK is a high rating, meaning it's very effective at moving heat away from your CPU.
Fan Airflow (71.93 CFM) & Air Pressure (1.86 mmH2O)
CFM (Cubic Feet per Minute) tells you how much air the fan moves, while mmH2O (millimeters of water) indicates how much static pressure the fan can generate to push air through the radiator's fins. Higher numbers in both generally mean better cooling, but also potentially more noise.
Alternatives
If you need quieter operation, look for AIOs with lower maximum dBA ratings or larger radiators (e.g., 360mm) that can achieve similar cooling at lower fan speeds. For extreme overclocking, consider custom liquid cooling loops or larger 360mm/420mm AIOs with higher CFM/mmH2O fans.
