ASUS ProArt LC 420 Premium All-In-One Liquid CPU Cooler with 420mm Radiator, Noctua NF-A14 IndustrialPPC 2000 PWM Fans, Illuminated System Status Meter & Broad Intel/AMD Socket Support

The PROART LC 420 is an ultra-high-capacity 420mm all-in-one liquid CPU cooler built specifically for content creators, 3D animators, and workstation professionals requiring extreme thermal dissipation and minimal acoustic noise. Engineered to cool high-TDP multi-core processors under continuous rendering workloads, the PROART LC 420 pairs an expansive 420mm aluminum radiator with three premium Noctua NF-A14 IndustrialPPC-2000 140mm PWM fans. Featuring an illuminated System Status Meter on the pump faceplate, it offers real-time visual telemetry for CPU performance and thermal loads without unnecessary RGB distractions. Powered by a advanced 3-phase pump motor and connected via 450mm reinforced sleeved tubing, it delivers superior cooling efficiency for high-end creative builds.

• High-Capacity 420mm Radiator: Massive surface area provides maximum thermal dissipation for top-tier, multi-core Intel and AMD processors under heavy rendering tasks.
• Noctua NF-A14 IndustrialPPC-2000 PWM Fans: Includes three high-performance 140mm fans delivering high airflow and static pressure with quiet operational acoustics.
• Illuminated System Status Meter: Understated pump housing features a visual meter display that tracks system load, temperatures, and fan speed trends at a glance.
• Advanced 3-Phase Pump Engine: High-efficiency pump motor ensures consistent, whisper-quiet liquid circulation across intensive computational workloads.
• Minimalist Workstation Aesthetic: Clean, all-black design with subtle metallic accents replaces flashy lighting with professional utility.
• Broad CPU Socket Support: Universal mounting hardware included for modern desktop sockets, including Intel LGA 1851/1700/1200/115X and AMD AM5/AM4.

PROART LC 420: Flagship 420mm Thermal Capacity for Workstations

The PROART LC 420 provides an optimal combination of extreme liquid cooling capacity, Noctua acoustic precision, and non-distracting studio aesthetics for heavy-duty production rigs.

System Status Telemetry & Clean Design

Designed to complement professional creative environments, the pump faceplate of the PROART LC 420 eliminates complex lighting in favor of a clean System Status Meter. The integrated telemetry bar provides real-time visual feedback on live CPU utilization and system temperatures.

Industrial-Grade Airflow & Extra-Long Tubing

Equipped with three 140mm Noctua IndustrialPPC PWM fans, the PROART LC 420 pushes maximum air volume through the thick 420mm radiator fins while maintaining low noise output. Featuring 450mm of thick, sleeved rubber tubing, it ensures flexible installation inside large workstation enclosures like the ProArt PA602.
