Product information

Description

Arctic Liquid Freezer III Pro 420 A-RGB is an all-in-one CPU liquid cooler with a 420 mm radiator and three 140 mm A-RGB fans. The compact pump module and black finish are designed for high-performance desktop builds and provide maintenance-free liquid cooling compatible with modern CPU sockets.

Advantages

The cooler delivers strong thermal performance through a large 420 mm radiator combined with three high-airflow 140 mm fans and a compact pump unit. Fans support PWM control and use Fluid Dynamic Bearings for long service life and low noise. The integrated solution is maintenance-free and compatible with current mainstream sockets, allowing straightforward installation in suitable cases.

Suitable for

  • High-performance desktop gaming PCs
  • Workstations with heavy CPU workloads (rendering, compilation)
  • Silent-oriented builds requiring efficient cooling at lower fan speeds
  • Systems using LGA 1700, AM4 or AM5 sockets

Key specifications

  • Type: All-in-one liquid cooler
  • Radiator size: 420 mm
  • Fan diameter: 140 mm (three fans)
  • Fan speed range: 400–2500 RPM
  • Maximum airflow: up to 186 m³/h
  • Static pressure: up to 5.2 mmH2O
  • Bearing type: Fluid Dynamic Bearing (FDB)
  • Fan control: PWM support
  • Supported sockets: LGA 1700, Socket AM4, Socket AM5
  • Colour: Black
  • Weight: 2.358 kg

How to use

Install the radiator and three 140 mm fans into a compatible case mounting location (top or front recommended for 420 mm radiators), secure the compact pump block onto the CPU following the supplied mounting brackets and instructions for your socket, and connect the fan and pump headers to the motherboard or controller using PWM connectors. Configure fan curves and A-RGB lighting in the motherboard or controller software as needed.

Usage recommendations

Ensure your case supports a 420 mm radiator and has sufficient clearance for three 140 mm fans. Use appropriate thermal paste and follow the provided installation guide for your specific CPU socket. For optimal balance of noise and cooling, set PWM curves in BIOS or software according to workload.
