Ratingen, Germany, February 02, 2023 — ASUS today announced the ProArt LC 420, the first all-in-one (AIO) cooler in the ProArt line. Expertly integrating premium tech into an elegantly understated design, the ProArt LC 420 is made for creators who seek high performance, low noise and chic style. It’s powered by a performant three-phase motor pump and Noctua IndustrialPPC fans, and an illuminated meter on the pump cover provides live system stats in the signature minimalist ProArt manner for real-time information at a glance. With subtle and graceful aesthetics that add a touch of refinement to your setup, the ProArt LC 420 is cool, quiet and classy — the perfect trifecta for any and all content creators.

Premium performance

As one of the few 420 mm AIO coolers on the market, the ProArt LC 420 can deliver some of the most powerful cooling available. And with its three renowned Noctua NF-A14 industrialPPC-2000 PWM 140 mm radiator fans, airflow can be delivered quietly.

The synergy of high performance and low noise extends to many other elements of the ProArt LC 420. A premium three-phase motor pump ensures a smooth and steady transfer of heat to the radiator, while being acoustically tuned to blend into the background. And the radiator itself is thicker than usual, creating extra coolant storage so that the fans and motor do not have to work as hard.

A 420 mm AIO cooler is also designed to scale to a large chassis, so the ProArt LC 420 also features 450 mm of reinforced, sleeved tubing that offers durability and flexibility for a variety of setups.

ProArt style

Instead of featuring RGB lighting that could distract a creator from their work, the ProArt LC 420 includes only a minimalist illuminated meter on the pump cover, separated into segments that represent different levels of fan speeds, temperature readings, or system loads. With this subtly illuminated meter, a user can check their system’s cooling performance with a quick glance. These settings can be found within Armoury Crate.

The ProArt LC 420 is designed to complement other components in the ProArt family, including motherboards, graphics cards, displays and more, empowering professional creators to design an entire system geared towards premium performance, tuned acoustics, and refined looks.

Availability & pricing

The ProArt 420 AIO cooler is available now in Germany, Austria and Switzerland at a recommended retail price of 329.90 EUR / CHF incl. VAT from specialist and online retailers and in the ASUS webshop (DE/AT & CH).
