White-edition AIO for mainstream sockets

The ROG STRIX LC II 240 ARGB WE is a 240 mm all-in-one liquid cooler finished in white with addressable RGB lighting. It mounts on Intel LGA 1700, 1200, 115x, 1366, 2011, 2011-3 and 2066 platforms as well as AMD AM4 and TR4. The copper cold plate transfers heat to an aluminum radiator through reinforced sleeved tubing. Builders wanting a coordinated white aesthetic with broad socket support will find it fits the brief.

Sustained-load behaviour from seventh-gen pump

The seventh-generation Asetek pump starts at 840 rpm and scales upward to maintain flow during prolonged workloads. Two 120 mm radiator fans reach 2500 rpm ±10 % and move 80.95 CFM each, providing steady airflow across the aluminum fins. This combination keeps coolant temperature stable during extended rendering or gaming sessions without relying on short burst performance. Users who need higher thermal capacity for extreme overclocking should consider larger radiators.

Thermals acoustics and power draw in daily use

At maximum fan speed the unit produces 37.6 dB(A) while delivering the rated airflow. The pump’s low minimum speed helps reduce idle noise, and the ARGB illumination adds no measurable thermal load. Power draw is limited to the 4-pin PWM fan headers and the pump connector, so no additional cables are required. Installers who prefer completely silent operation at full load may find the acoustic output noticeable.

Questions about this item

How loud are the two 120 mm fans when they spin at 2500 RPM during a full-day workload?

The fans produce 37.6 dB(A) at maximum speed, so sustained loads stay at that level.

Does the package include mounting hardware for an Intel LGA 1700 motherboard, or must I buy a separate bracket?

The cooler ships with brackets for Intel LGA 1700, 1200, 115x, 2011, 2011-3 and 2066 sockets.

Will the 240 mm radiator and pump fit inside a case that only has room for a 120 mm AIO?

No, the radiator is 240 mm long and requires two 120 mm fan slots, so a 120 mm-only case will not work.
