The Thermalright Assassin King 120 SE ARGB is specified as a single-tower CPU air cooling solution engineered for efficient thermal dissipation. Heat is moved from the processor using five 6 mm diameter heatpipes connected to an aluminum fin stack. This configuration is designed to manage thermal loads while maintaining a narrow cooler profile for compatibility with diverse PC builds. The overall assembly measures 148 mm in height, a critical dimension for verifying case clearance above the CPU socket.
Thermal regulation is controlled by a single 120 mm fan which integrates Pulse-width Modulation (PWM) support for dynamic speed adjustment. The fan operates within a rotational range up to 1550 RPM, providing a maximum airflow of 66.17 CFM and a static pressure of 1.53 mmH2O. At peak operational speed, the unit generates a maximum noise level of 25.6 dB. Mounting hardware is included to ensure compatibility with modern processor platforms, including Intel LGA 1700 and AMD AM5 sockets.
