The Thermalright Assassin King 120 SE ARGB CPU Air Cooler White (Assassin King 120 SE White ARGB) is a precision-engineered single-tower cooling solution configured to balance thermal efficiency with bright customizable design aesthetics. Tailored specifically for modern mid-tier computing builds, this matte white thermal solution integrates high-density heat dissipation paths while offering broad chassis compatibility across popular desktop configurations.
This advanced thermal framework relies on five 6mm optimized copper heatpipes using cutting-edge anti-gravity capillary technology to accelerate core heat dispersion away from the nickel-plated pure copper base. Paired with a high-performance 120mm PWM static pressure fan utilizing 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-C12CW-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.
