ASUS ROG STRIX LC II 240 ARGB Processor All-in-one liquid cooler 12 cm White

The ASUS ROG STRIX LC II 240 ARGB White is an all-in-one liquid CPU cooler designed to deliver efficient thermal management with a clean white finish and addressable RGB lighting. The 240 mm radiator paired with dual 120 mm fans offers a balance of cooling performance and low acoustic profile for mainstream and high-performance desktop processors. The unit combines a compact pump assembly and pre-filled loop for straightforward installation and maintenance-free operation.

Advantages

This AIO liquid cooler provides consistent CPU temperature control through a 240 mm radiator and two 120 mm fans with a combined airflow capacity up to 80.95 cfm per fan and an airflow rate of 137.5 m³/h. The white shroud and ARGB illumination allow visual integration with white or light-themed builds. The integrated pump and closed-loop design reduce maintenance needs compared with custom water-cooling, while the included fans are tuned for a balance between airflow and noise.

Suitable for

• Gaming desktops that require improved CPU cooling for sustained load
• Content creation workstations where thermal stability supports long rendering tasks
• Compact ATX or micro-ATX builds prioritizing a white aesthetic
• PC builders seeking an easy-to-install, maintenance-free liquid cooling solution

How to use

Mount the radiator to a compatible case location supporting 240 mm radiators, typically top or front positions, and secure the two 120 mm fans in either push or pull orientation according to your airflow preference. Install the pump block onto the CPU socket with the manufacturer-provided mounting hardware, ensuring even contact and proper thermal paste application where required. Connect the fans and pump to the motherboard or fan/RGB controllers using the supplied power and ARGB connectors, and configure fan curves and RGB effects in the system firmware or Asus lighting software.

Recommendations

For optimal thermal performance, position the radiator to promote consistent case airflow (intake or exhaust depending on your setup) and configure fan curves to increase speed under sustained CPU load. Periodically check mounting screws and cable connections during routine system maintenance; the closed-loop design requires no coolant refill.
