The ASUS ROG Strix LC II 240 ARGB White Edition is a closed-loop all-in-one liquid cooler designed for enthusiasts who want strong thermal performance alongside a cohesive white-and-ARGB aesthetic. It suits builders pairing unlocked AMD or Intel processors with ROG motherboards, addressing the need for effective CPU cooling without sacrificing visual integration. Aura Sync lighting on both the pump cover and radiator fans lets it coordinate with other ROG components in the build.
Why This Product
-
7th-gen Asetek pump for quiet operation
— The 7th-generation Asetek pump runs from 840 RPM at its lower end, keeping noise down during lighter workloads while scaling up to 2,800 RPM when thermals demand it.
-
ROG radiator fans outperform generic AIO fans
— The dual 120 mm ROG ARGB fans deliver 81 CFM airflow and 5.0 mmH2O static pressure — 14% more airflow and 7% greater static pressure than the referenced comparison AIO fan.
-
Aura Sync ARGB across pump and fans
— The illuminated ROG logo on the NCVM-coated pump cover and the ARGB radiator fans both support Aura Sync, enabling coordinated lighting effects across compatible ROG components.
-
Reinforced sleeved tubing
— The 380 mm sleeved rubber tubing is reinforced for increased durability and gives the loop a clean, finished appearance consistent with the Moonlight White theme.
-
Broad socket compatibility
— It supports Intel LGA 1851, 1700, 1200, and 115x sockets alongside AMD AM5, AM4, and TR4/sTRX4 (TR4/sTRX4 mounting bracket is included with the processor package, not this cooler).

Best For / Trade-offs
Best for:
-
ROG ecosystem builders
who want pump-cover and fan lighting that synchronises with Aura Sync motherboards and other ROG components.
-
White-themed builds
where the Moonlight White aesthetic and ARGB fans need to match case and motherboard colour schemes.
-
Overclocked Intel and AMD CPUs
on supported sockets, including current-gen LGA 1700/1851 and AM5 platforms.
-
Noise-conscious users
who still need meaningful cooling — the Asetek pump starts at 840 RPM and the fans run from 800 RPM, keeping idle acoustics low.
Trade-offs:
-
Compact ITX cases
that cannot accommodate a 121 × 272 × 27 mm radiator plus 380 mm of tubing routing.
-
TR4/sTRX4 users
who have not sourced the dedicated mounting bracket — it is not in the box with this cooler.
-
Builders avoiding RGB
— both the pump cover logo and the radiator fans include ARGB lighting with no non-illuminated variant available in this SKU.
-
Noise-critical professional environments
— the fans reach 37.6 dB(A) at maximum speed, which may be audible in quiet office settings.
