The ASUS ROG Strix LC II 280 ARGB is an all-in-one liquid CPU cooler designed for thermal management in high-performance PC builds. The system is built around a 280mm aluminum radiator paired with two 140mm fans, which are optimized for static pressure to effectively move air through the radiator fins. A copper cold plate makes direct contact with the CPU to facilitate heat transfer to the circulating liquid. The pump operates at a fixed speed of 2800 RPM to maintain consistent coolant flow.
This cooler offers broad compatibility with current Intel and AMD sockets, including LGA 1700 and AM5. Fan speeds are adjustable via PWM control, operating between 700 and 2100 RPM to balance cooling needs with noise output. The unit includes 380mm of sleeved rubber tubing, providing installation flexibility within mid-tower and full-tower cases. Addressable RGB lighting is integrated into both the pump block and fans, which can be synchronized with other compatible hardware using ASUS Aura Sync software.
