ASUS has just unveiled the ProArt LC 420, a game-changing addition to their ProArt line of All-in-One (AIO) Coolers. This sleek and sophisticated cooler is a dream come true for creators who value both performance and style.

The ProArt LC 420 is equipped with a powerful three-phase motor pump and Noctua IndustrialPPC fans, ensuring top-notch cooling capabilities without sacrificing peace and quiet. But what sets this cooler apart is its attention to aesthetics. With an illuminated meter on the pump cover, creators can easily monitor their system’s stats at a glance, all while maintaining the minimalist ProArt design.

When it comes to performance, the ProArt LC 420 truly shines. As one of the few 420 mm AIO coolers on the market, it offers unparalleled cooling power. Its three Noctua NF-A14 industrial PPC-2000 PWM 140 mm radiator fans work silently to deliver optimal airflow. The premium three-phase motor pump ensures efficient heat transfer to the radiator, while the thicker radiator design provides extra coolant storage, reducing strain on the fans and motor.

Not only does the ProArt LC 420 excel in performance, but it also excels in versatility. With 450 mm of reinforced, sleeved tubing, this cooler is designed to fit seamlessly into a variety of setups and chassis sizes.

But let’s talk style. The ProArt LC 420 embraces a refined and understated aesthetic that complements any workspace. Instead of flashy RGB lighting, it features a minimalist illuminated meter on the pump cover. This meter displays fan speeds, temperature readings, and system loads, allowing creators to effortlessly monitor their cooling performance without distractions. All these settings can be easily accessed through ASUS’ Armoury Crate software.

Furthermore, the ProArt LC 420 is designed to seamlessly integrate with other components in the ProArt family, including motherboards, Graphics Cards, and displays. This means that professional creators can build an entire system that not only delivers premium performance but also boasts a cohesive and sophisticated look.

In conclusion, the ASUS ProArt LC 420 is a true game-changer for content creators. With its powerful cooling capabilities, elegant design, and seamless integration with other ProArt components, it’s the perfect choice for those who demand nothing but the best. Say goodbye to noisy and unsightly coolers – the ProArt LC 420 is here to revolutionize your creative workflow.

Technology Explained


PWM: Pulse Width Modulation (PWM) is a type of technology used in the computer industry that allows for control over pulse and frequency. It works by modulating an output signal’s pulse width or duty cycle to vary the on and off times of the signal. This technology can be used to control and regulate different DC motor, lighting, and other devices. In the computer industry, PWM is often used to control the speed of CPU and GPU fan speeds for improved cooling. It is also used to control backlighting levels on devices such as keyboards or monitors. PWM is versatile, cost-effective, and efficient; as such, it is an important technology in the computer industry.
