ASUS ROG Strix LC II 240 AIO Liquid CPU Cooler

Overview

The ASUS ROG STRIX LC II 240 is an all-in-one liquid CPU cooler designed to provide efficient and reliable thermal management for modern processors. Featuring a 240 mm aluminum radiator and two 120 mm PWM fans capable of moving up to 80.95 CFM of air, it ensures your CPU stays cool during gaming, content creation, or heavy multitasking. The cooler incorporates a 7th generation Asetek pump that operates quietly at 840 rpm during light workloads and ramps up as needed to maintain optimal temperatures.

Key features

• 240 mm aluminum radiator paired with two 120 mm PWM fans for effective heat dissipation
• Fans can reach speeds up to 2500 rpm, delivering strong airflow and static pressure for better cooling performance
• 7th generation Asetek pump with low idle speed to minimize noise during light use
• Copper cold plate that directly contacts the CPU to transfer heat quickly into the coolant
• Reinforced and sleeved 380 mm tubing for flexible installation and protection against kinks and abrasion
• Integrated ARGB lighting on the pump cover with NCVM coating for smooth and consistent illumination that matches your build’s aesthetics
• Comes with mounting hardware compatible with a wide range of Intel and AMD sockets, including the latest LGA 1700 and AM5
