Product Description
ProArt LC 420 Refined Cooling Masterpiece for Quiet Performance

Premium Cooling Power with Artistic Precision
The ASUS ProArt LC 420 is the ultimate CPU liquid cooling solution crafted for creators who demand top-tier thermal performance with quiet efficiency. This elegant cooler incorporates three Noctua NF-A14 industrialPPC-2000 PWM 140 mm fans that deliver exceptional airflow with low noise, making it perfect for high-demand workloads. At the core of its power is a high-efficiency three-phase motor, designed to maintain ultra-cool temperatures even under heavy rendering, editing, or multi-threaded computation tasks.
Live System Stats in Minimalist Form
The ProArt LC 420 sets itself apart with its innovative illuminated system meter. Discreetly embedded in the pump cover, this display provides real-time data such as CPU temperatures, system load, and fan speeds. This allows creators to monitor their system at a glance, all while keeping the cooler’s aesthetics minimalistic and professional. Whether on camera or in studio, the sleek visual profile of the LC 420 complements any ProArt build.

Built for Longevity and Compatibility
Durability and flexibility come standard with reinforced 450 mm sleeved tubing, ensuring broad chassis compatibility and long-term reliability. The thick 456 mm radiator increases coolant capacity, enhancing thermal headroom. With comprehensive support for AMD AM5/AM4 and Intel LGA 1851/1700/1200/115x sockets, the ProArt LC 420 adapts easily to a wide range of professional PC builds. Backed by a 6-year warranty, it’s a long-term cooling solution for creators who take their craft seriously.
