The Cooler Master Atmos II 360 is a high-performance 360mm all-in-one liquid CPU cooler optimized for the latest high-TDP processors, including Intel Core Ultra 9 (LGA 1851) and AMD Ryzen 9000 Series (AM5). Its redesigned dual-chamber pump with FreeForm 2.0 technology features an enlarged copper cold plate and improved internal flow channels for superior heat transfer and exceptional cooling capacity on extreme workloads and overclocking.



A standout feature is the integrated dedicated VRM fan built into the pump block, providing active airflow directly over motherboard power delivery components for enhanced stability during heavy CPU loads. Three pre-installed SickleFlow Edge 360 ARGB 120mm PWM fans (0–2500 RPM, up to 70.2 CFM, 3.61 mmH₂O) with loop-style blades deliver strong static pressure and quiet operation, while the extended 400mm sleeved tubing offers greater flexibility for radiator placement in larger cases.

Full addressable Gen 2 RGB lighting on the pump and fans synchronizes seamlessly via Cooler Master MasterCTRL software or standard motherboard headers. Universal tool-free mounting and broad compatibility make installation straightforward. With its advanced pump design, targeted VRM cooling, premium ARGB aesthetics, and flagship-level thermal performance, the Atmos II 360 is the ideal AIO solution for cutting-edge Intel and AMD platforms demanding maximum stability and silence under intense loads.
