ASUS PROART LC 420

ASUS PROART LC 420
The ASUS ProArt LC 420 water cooler is an all-in-one (AIO) closed-loop liquid system designed to dissipate heat from multi-core processors in workstations. This 420mm CPU cooler uses a three-phase motor pump and three 140mm Noctua NF-A14 fans to ensure cooling at a low noise level. The design matches the minimalist style of the ProArt series and is designed for work builds without RGB backlighting.
Key features of the ASUS ProArt LC 420 water cooler
- Three Noctua NF-A14 industrialPPC-2000 PWM fans dissipate heat from the radiator
- Powerful three-phase pump motor operates with low vibration
- Illuminated meter on the pump displays temperatures, load and fan speeds
- Reinforced braided tubing for easier installation
- Wide socket support includes modern Intel and AMD platforms
Performance and quiet operation
The core of the cooling performance comes from three Noctua NF-A14 industrialPPC-2000 PWM fans. These fans reach speeds of up to 2000rpm and, combined with the three-phase motor of the water pump, ensure airflow through the radiator. The entire assembly achieves an airflow of up to 107CFM at an acoustic pressure of 31.5dB(A), even under heavy processor load.
Design and system overview
The cooler uses an understated design with no RGB elements, which matches its focus on professional use. The pump housing features an illuminated meter that displays selected system information in real time. This lets you monitor system load, component temperatures or fan speeds without having to run separate monitoring software.
Installation and compatibility
Installation into a computer case is made easier by the reinforced braided tubing, which provides the necessary flexibility during assembly. The radiator is designed to be compatible with standard computer cases while also contributing to the overall durability of the build. The cooler supports a wide range of processor sockets on both Intel and AMD platforms.
