The Thermalright Assassin King 120 SE ARGB CPU Air Cooler Black (Assassin King 120 SE ARGB Black) is a high-efficiency single-tower cooling solution configured to balance reliable thermal performance with customizable, blacked-out aesthetics. Tailored carefully for mainstream computer setups, this matte black thermal solution optimizes heat dissipation paths while offering an exceptionally compact clearance profile across modern chassis configurations.
This advanced thermal system implements five 6mm copper heatpipes utilizing cutting-edge anti-gravity capillary technology to accelerate core heat dispersion away from the nickel-plated pure copper base plate. Paired with an optimized 120mm PWM static pressure fan featuring premium Fluid Dynamic Bearings and integrated addressable RGB diodes, it delivers a robust cooling potential up to a 235W threshold while keeping the overall physical footprint low enough to fit space-restricted mid-tower layouts.
Key Features & Specifications
AGHP Anti-Gravity Heatpipe Matrix: Implements five premium 6mm copper heatpipes engineered with special internal capillary structures to guarantee unrestricted heat transfer efficiency in both horizontal and vertical case mounting configurations.
Compact 148mm Vertical Clearance: Features a reduced physical height profile that comfortably fits into a vast majority of mainstream standard ATX and Micro-ATX chassis structures without making contact with side panels.
Addressable RGB Performance Fan: Powered by a color-matched 120mm TL-C12C-S fan that outputs up to 66.17 CFM of airflow while supporting 5V 3-pin ARGB motherboard synchronization.
Sealed Fluid Dynamic Bearings: The integrated S-FDB fan bearing architecture substantially lowers mechanical rotation friction, capping sound ceilings at 25.6 dBA to maintain true acoustic quietness.
Mainstream Multi-Socket Support: Includes reliable multi-platform hardware fasteners providing uniform installation pressure across current desktop layouts, including Intel LGA 1851/1700 and AMD AM5/AM4 interfaces.

Important Product Information
Aesthetic & Lighting Connectivity: The integrated addressable lighting array uses a standard 3-pin 5V ARGB header interface, requiring a compatible motherboard connector or independent physical hub to operate the custom color profiles safely.
Clearance & Installation Alignment: While the compact 148mm tall layout offers outstanding physical motherboard versatility, ensure your system power supply unit is properly routed before tightening down the primary structural crossbars.
