## Long description

The Cooler Master MasterLiquid Atmos II 240 Pixel LED is a high-performance all-in-one liquid cooling solution designed to provide efficient thermal management for modern processors. This system features a dual-chamber pump design and a customizable Pixel LED panel, allowing users to display system statistics, custom images, or text. With its ultra-low profile pump and pre-installed SickleFlow Edge ARGB fans, it combines effective heat dissipation with a sleek, compact aesthetic suitable for various PC builds.
Advantages
The cooling system utilizes a patented dual-chamber design that optimizes water flow directly to the CPU hotspot, significantly improving heat transfer efficiency. The pump housing is constructed from industrial-grade PPS and fiberglass, ensuring long-term durability and resistance to high temperatures. Users benefit from the integrated Pixel LED panel, which offers extensive personalization options via dedicated software. Furthermore, the inclusion of high-RPM, low-vibration fans ensures that the system maintains strong cooling performance while keeping noise levels to a minimum.
Suitable for
High-performance gaming PCs
Professional workstations requiring stable thermal management
Compact PC builds where space is limited
Systems requiring visual customization and monitoring
When it may not be suitable
This liquid cooling kit may not be suitable for ultra-small form factor cases that cannot accommodate a 240mm radiator. Additionally, users who prefer a completely minimalist aesthetic without any lighting or display features might find the Pixel LED panel unnecessary for their specific build requirements.
Key specifications
Radiator size: 240mm
Fan diameter: 120mm
Bearing type: Loop Dynamic Bearing (LDB)
Airflow: 240.35 m³/h
Supported sockets: LGA 1150, 1151, 1155, 1156, 1200, 1700, 1851, AM4, AM5
Pump housing material: PPS and fiberglass
Lighting: Pixel LED panel and ARGB fans
How to use
Installation is simplified through the included quick-mount kit, which is compatible with a wide range of Intel and AMD processor sockets. Begin by securing the radiator to your case and mounting the pump block onto the CPU using the appropriate bracket for your socket type. Apply the included CryoFuze thermal paste to the processor surface before attaching the pump. Connect the fan and pump cables to the motherboard headers, ensuring the PWM settings are configured in the BIOS for optimal performance. Use the MasterCTRL software to customize the Pixel LED display and monitor system information.
What to consider before purchase
Verify that your PC case has sufficient clearance for a 240mm radiator.
Check motherboard compatibility for the specific offset mounting brackets if using an LGA 1851 socket.
Ensure your motherboard has available headers for ARGB and PWM fan control.
Usage recommendations
For the best thermal results, ensure the radiator is mounted in a position that allows for unobstructed airflow. Regularly check the fan speeds via your motherboard software to maintain a balance between cooling performance and acoustic comfort.
