All-in-one liquid cooler ASUS TUF GAMING LC III 240 ARGB WHT – 240 mm radiator, 2x 120 mm fans, PWM, white

The ASUS TUF Gaming LC III 240 ARGB White Edition is an all-in-one liquid CPU cooler with a 240 mm radiator and pre-installed 120 mm ARGB fans. It features a white finish and an Aura ARGB-lit pump top, an upgraded three-phase pump design, and reinforced sleeved 400 mm tubing to provide reliable thermal management for gaming and high-performance PCs.

Advantages

This cooler delivers higher airflow and static pressure compared with the previous TUF Gaming LC II series, improving heat dissipation. Pre-installed integrated fans with a single-cable connection simplify installation and cable management. The upgraded pump (three-phase, six-slot, four-pole) increases lifespan and efficiency while reducing noise. Compact 240 x 120 x 26.6 mm radiator dimensions and universal white styling make the unit easy to fit and visually compatible with many builds.

Suitable for

• Gaming desktop builds requiring efficient CPU cooling
• Compact or mid-tower systems where a 240 mm radiator fits
• PC enthusiasts who want ARGB lighting and coordinated white components
• Users upgrading from air cooling to an all-in-one liquid solution

How to use

Mount the radiator to a compatible case location that supports a 240 mm radiator. Attach the pre-installed 120 mm ARGB fans to the radiator, then secure the radiator to the case using the appropriate screws. Install the pump block on the CPU and fasten using the supplied mounting hardware for the target socket (Intel LGA1851/1700/1200 or AMD AM5/AM4). Connect the single cable to the motherboard header for power and ARGB control and enable PWM fan control in the BIOS or via motherboard software to optimise cooling and acoustics.

Recommendations

Ensure compatibility with your case for a 240 mm radiator and confirm the chosen motherboard has the required fan and ARGB headers. Allow clearance for RAM and VRM components when positioning the pump block. Periodically check tubing and fittings for secure connections and proper airflow to maintain optimal thermal performance.
