Quiet performance meets quiet style: Introducing the ProArt LC 420 AIO liquid CPU cooler

Content creators quite regularly task their CPUs with demanding workloads. Exporting projects, transcoding video, or rendering a 3D model can put every core and thread in your processor to work, potentially for long stretches of time. To help you keep your high-end CPU operating at optimal temperatures without undue fan noise, we’re debuting the ProArt LC 420 all-in-one liquid CPU cooler. With a beefy radiator, three 140mm Noctua fans, an illuminated meter on the pump cover, and the signature minimalist ProArt aesthetic, the ProArt LC 420 offers exceptional, quiet, and stylish cooling performance.

Equipped for high-end cooling

Key technologies equip the ProArt LC 420 to overcome the thermal challenges presented by the latest multi-core CPUs. It starts with the cooler’s beefy radiator. Not only does it provide a large surface area for heat dissipation, but this thicker radiator also allows for an increased volume of coolant. These upgrades give the ProArt LC 420 the significant sustained cooling power it needs to beat the heat when you fire up a longer-running task.

Quiet operation is a must-have for many creators, so we equipped the ProArt LC 420 AIO liquid cooler with an advanced three-phase motor that keeps the coolant moving without distracting you with noise. For wide chassis compatibility, even with larger EATX cases like the all-new ProArt PA602 chassis, the ProArt LC 420’s tubing is 450mm long, and features a braided mesh sleeve for durability.

For the ProArt LC 420’s fans, we turned to one of the most respected names in the industry. A trio of Noctua NF-A14 industrialPPC-2000 PWM fans keep cooling air moving through the radiator. As 140mm fans, they’re capable of moving a similar amount of air more quietly than common 120mm fans can. They’re also more than capable of ramping up when you need them the most — with a top rotational speed of 2000 RPM, they’re ready to kick into high gear during a challenging workload.

Minimalist design, intuitive function

Minimalist design is a signature element of all ProArt components, monitors, laptops, and prebuilt desktop PCs. To help you keep your focus on your projects, these products feature clean lines, unobtrusive colors, and very few LED lighting effects. Carefully placed accents set off these components with a dash of elegance and sophistication.

The ProArt LC 420 perfectly matches the aesthetic of your ProArt PC build with its subdued charcoal-colored surfaces and gold ProArt accents on the pump housing. To help you track vital information at a glance, the pump housing also includes an innovative illuminate meter. This thin strip of LEDs displays real-time system information, such as system load, temperatures, and fan speeds. Through the Armoury Crate app, you can configure this meter to best fit your needs at any given moment.

Wide compatibility

The ProArt LC 420 AIO liquid cooler offers wide compatibility with multiple generations of CPU sockets from both Intel and AMD. No matter which brand you favor, whether you’re building a PC with a cutting-edge processor or getting additional value out of a last-gen model, the ProArt LC 420 is almost certainly compatible. With support for LGA 1700 and AM5 sockets, this AIO liquid cooler is ready for the best CPUs and motherboards of today, and it offers compatibility for older LGA 1200, LGA 115X, and AM4 sockets as well.
