The ASUS ROG Strix LC III 240 ARGB is an all-in-one liquid CPU cooler designed for thermal management in PC builds. It integrates a 7th V2 generation Asetek pump with a copper cold plate to facilitate heat transfer from the processor. This heat is then moved to a 240mm aluminum radiator, which is cooled by two ROG STRIX AF-12S 120mm fans. The system is engineered to provide consistent cooling performance for compatible Intel and AMD CPUs under various load conditions.
The unit features 400mm of sleeved tubing, offering flexibility for installation in different chassis configurations. Its two 120mm fans operate on a PWM-controlled speed range of 800 to 2200 RPM, producing up to 70.38 CFM of airflow and 3.92 mmH₂O of static pressure. The fans and pump head are equipped with addressable RGB lighting that can be synchronized with other components through ASUS Aura Sync. This cooler supports a wide range of sockets, including Intel's LGA 1700 and 1851, as well as AMD's AM4 and AM5 platforms.
