ROG Strix LC II 240 delivers high-performance CPU liquid cooling with sleek, modern aesthetics. Featuring a closed-loop design and ROG radiator fans, the cooler unleashes the full potential of an Intel® or AMD CPU while enabling subtle multicolor lighting effects to accentuate your build.

NEXT-LEVEL CUSTOMIZATION
Emanate Your Style
From end to end, ROG Strix LC II 240 showcases the iconic ROG aesthetic. Engraved ROG lettering on the radiator’s side complements the iridescent lettering on the hubs of each fan. And the Aura Sync-compatible pump cover radiates the new ROG logo in any color you choose.

Optimized Fan Design
The ROG radiator fans are specifically tuned to deliver optimum performance on ROG Strix LC II series radiators. The fans generate 81 CFM / 5.0 mmH2O for exceptional cooling efficiency.

Enhanced Pump Design
ROG Strix LC II series is equipped with the latest cooling-plate design. Machined from pure copper, the plate features an array of fine micro-channels that reduce thermal resistance and increase surface area, resulting in lower CPU temperatures.

PWM-Controlled Pump and Fans
PWM control enables both the pump and radiator fans to spin at slower speeds when the CPU is idling or under light load, helping to keep noise levels to a minimum.
