ASUS ROG Strix LC III 240 ARGB AIO Liquid CPU Cooler - White Edition
The ASUS ROG Strix LC III 240 ARGB is an all-in-one liquid CPU cooler built for enthusiasts and high-performance builders running AMD Ryzen or Intel Core processors. It combines a 7th-generation Asetek V2 pump with a 360° rotatable water block and ROG ARGB fans to manage heat from demanding workloads while synchronizing with ROG motherboard lighting.
Why this product
360° rotatable water block with magnetic design
The water block rotates freely to fit your case layout and keep the ROG logo oriented the way you want it, without compromising pump connection or flow.
0dB fan mode in low-load conditions
Fans automatically stop spinning when the CPU is cool, eliminating noise during everyday use and reducing power draw.
Gen7 V2 Asetek pump with updated cold plate
Delivers up to 100 watts additional cooling capacity and reportedly runs up to 0.5°C cooler than the previous generation, with a quieter motor.
Aura Sync Gen 2 RGB integration
Automatically detects and syncs with ROG motherboard lighting, supporting 10+ custom effects without additional software configuration.
Reinforced sleeved tubing
400 mm of durable sleeved rubber tubing resists kinking and extends the cooler's lifespan under vibration and movement.
- Radiator size240 mm (2 × 120 mm fans)
- Pump generationAsetek Gen7 V2
- Fan noise level36 dB(A) at max speed
- Water block materialCopper cold plate
- RGB supportAura Sync Gen 2
- Warranty6 years
- SKUASU-2232
- EAN4711387453117
- AMD socket AM5 and AM4 processors.
- Intel LGA 1851, 1700, 1200, and 115x socket processors.
- ASUS ROG motherboards with Aura Sync Gen 2 RGB headers for synchronized lighting.
- PWM and DC fan control modes supported.
- Requires a case with space for a 272 × 121 × 27 mm radiator and two 120 mm fans (standard ATX/mid-tower and larger cases typically accommodate it).
Best for
- High-end gaming and streaming builds that need reliable cooling under sustained load.
- Enthusiasts who value silent operation and RGB customization on ROG-branded systems.
- Builders in cases where a 240 mm radiator fits better than larger models or air coolers.
- Users who want low noise without sacrificing cooling performance in everyday tasks.
Trade-offs
- Cases without 240 mm radiator clearance. The radiator measures 272 × 121 × 27 mm and requires a compatible mounting location.
- Intel or AMD systems without Aura Sync headers. The RGB synchronization is ASUS-specific and will not integrate with third-party motherboards.
- Extreme overclocking on the highest-end CPUs. While capable, a 360 mm or larger radiator may offer better sustained cooling under extended load.
- Environments requiring minimal power draw. At peak fan speed the cooler will consume more power than a passive air cooler, though 0dB mode reduces this at idle.
