Advanced Cooling Performance
The ROG Strix LC III 240 ARGB is built around Asetek’s Gen7 v2 pump, which delivers up to 100W more cooling capacity compared to the previous generation. Its updated cold plate design ensures efficient heat transfer from the CPU, keeping temperatures lower during intensive workloads. This makes it ideal for overclocking and sustained gaming sessions where thermal headroom is critical.
360° Rotatable Water Block
Installation flexibility is enhanced with a magnetic, 360° rotatable water block. This allows the cooler to be mounted in multiple orientations without restricting tubing direction, simplifying integration into complex PC builds. The magnetic design also ensures a secure and easy fit during setup.
Dynamic ARGB Lighting
Customise your system’s aesthetics with Aura Sync-compatible ARGB lighting on both the water block and radiator fans. Choose from a range of preset effects or use Aura Creator to design unique lighting profiles that react to system activity. The lighting can be synchronised across compatible ASUS components for a cohesive look.
Quiet Operation
Despite its high-performance cooling, the ROG Strix LC III 240 ARGB maintains low noise levels, with fans operating at a maximum of 36 dB. PWM fan control allows for automatic speed adjustment based on CPU temperature, balancing cooling performance with acoustic comfort.
LCD Display Integration
A built-in LCD screen on the water block offers real-time system monitoring or the ability to display custom animations. This feature adds both functionality and a personalised touch to your build, making system stats visible at a glance.
