The Asus ProArt LC 420 AIO Liquid CPU Cooler is built for users who want reliable, high-performance cooling with a clean, professional look—ideal for gaming rigs, content creation workstations, and demanding daily multitasking. With a 420mm-class radiator and a carefully engineered liquid cooling loop, this cooler helps keep CPU temperatures under control during heavy workloads, helping maintain stability when performance matters most.
At the heart of the ProArt LC 420 is a high-quality aluminum radiator sized 456 x 140 x 30 mm, paired with a copper water block measuring 78 x 78 x 49 mm. This combination supports efficient heat dissipation, making it a strong choice for systems that run long sessions—such as rendering, streaming, and high-FPS gaming—where sustained thermal management is essential. The radiator’s size also gives you more surface area compared to smaller AIO solutions, which can be beneficial when you want cooler operation without relying solely on aggressive fan behavior.
Included with the cooler is a Noctua NF-A14 IndustrialPPC 2000 PWM fan, engineered for performance across a wide speed range of 800 to 2000 RPM. The fan delivers up to 107 CFM airflow and 4.18 mmH2O static pressure, which is particularly useful for AIO radiators where airflow must effectively pass through dense fin stacks. With PWM control, the cooler can adapt fan output to changing CPU loads, helping you balance cooling performance and everyday acoustics.
The ProArt LC 420 is rated at 31.5 dB(A), supporting a quieter experience during typical use. This makes it suitable for setups where you want less distraction—such as office work, study environments, and creator workflows—while still having the cooling headroom needed for demanding tasks. Compared to basic cooling solutions, an AIO like this can offer smoother thermal behavior under fluctuating workloads.
For installation comfort and long-term durability, the cooler uses sleeved rubber tubes with a 450 mm length. The added sleeve protection helps improve cable/tube resilience during building and future maintenance, while the tube length supports flexible routing inside most compatible cases. This is especially helpful when you’re building a clean layout with careful cable management.
The Asus ProArt LC 420 features AURA Sync support, allowing you to synchronize RGB lighting effects with other compatible components. If you’re building a cohesive aesthetic, this helps you match lighting styles across your system rather than relying on isolated effects. It’s a practical feature for users who want both performance and a polished visual theme.
This AIO cooler supports Intel LGA 1700, 1200, 115x sockets and AMD AM5, AM4 sockets. That wide compatibility makes it a convenient option if you plan to upgrade platforms or build a system around either Intel or AMD CPUs. Before purchasing, ensure your motherboard supports one of these listed sockets and confirm your PC case can accommodate a 420mm radiator for the best fit.
The package includes the CPU liquid cooler with pre-applied thermal compound, a 1-to-3 fan splitter cable, an accessory pack of screws and brackets, and a quick start guide. For peace of mind, the cooler comes with a 6-year warranty, making it a dependable long-term cooling investment for your PC build.
