Its customizable ARGB illumination adds modern flair to any build, while PWM control ensures the perfect balance between performance and noise levels.

– Powerful Thermal Solution

At the heart of the Assassin King 120 SE ARGB are FIVE 6mm direct-contact heatpipes that rapidly transfer heat from the CPU to the aluminum fin stack. This efficient heat exchange system maintains optimal temperatures even under full CPU load, ensuring stable performance for high-intensity applications.

– 120mm PWM ARGB Fan

Equipped with a 120mm PWM fan, this cooler provides strong airflow and static pressure to push air effectively through the heatsink. Fan speed adjusts automatically based on CPU temperature, offering dynamic cooling when needed and quiet operation when idle.
The fan’s design focuses on delivering high airflow while maintaining low acoustics, making it ideal for both performance-oriented and silent builds.

– Customizable ARGB Lighting

The built-in ARGB lighting offers vibrant and fully customizable lighting effects that enhance your system’s aesthetics. By connecting to a motherboard’s 5V 3-pin ARGB header, you can synchronize lighting with other ARGB components and control effects via popular RGB software such as:

• ASUS Aura Sync
