The Arctic Liquid Freezer III Pro 420mm A-RGB Liquid Cooler Black features a solid 38mm thick aluminium radiator with three P14 Pro A-RGB 140mm fans (400-2500 RPM) and an integrated PWM-controlled VRM fan atop the pump to keep motherboard voltage regulators cool. It supports Intel (LGA 1700 & LGA 1851) and AMD (AM4 & AM5) sockets via offset contact-frame mounting, includes pre-applied MX-6 thermal paste, reinforced braided tubing and vibrant addressable RGB LEDs in both fans and pump-all with tidy single-cable control.

Integrated VRM Fan
PWM-controlled fan lowers the voltage regulator temperature, ensuring stable performance.
Offset Mounting for Intel and AMD
Shifts the cold plate to the CPU hotspot for more efficient heat transfer.
Intel Contact Frame
Optimised contact pressure distribution for longer CPU lifespan and improved heat dissipation.
Integrated Cable Management
Fan cables integrated into the sleeving simplify installation and minimise cable clutter.

The New P14 Pro Fans
More Performance at Any Speed
The P14 Pro unleashes its full potential: quieter and more powerful at low speeds, with greater performance reserves under load—for maximum cooling without compromise.
- 400—2500 rpm Speed
- Fluid Dynamic Bearing
- 5.2 mmH₂O Static Pressure
- 110 cfm | 186 m³/h Airflow

Premium-Class Radiator
The 38 mm radiator not only enhances heat dissipation but also holds more liquid than conventional 27 mm radiators. This reduces heat buildup and ensures more efficient handling of temperature spikes.

Premium Tubing
Reinforced EPDM tubing with braided sheathing for increased durability.

Easy Installation
Pre-installed, pre-wired fans, straightforward mounting, and an animated online manual.

Includes MX-6 Thermal Paste
Simply apply in a cross pattern—the water pump’s cold plate distributes the paste evenly.

Two Control Options
With the splitter cable, the pump, VRM fan, and radiator fans can be controlled separately or synchronised via a single PWM signal with the all-in-one cable.

Check Your Case for Compatibility
Please note that the Liquid Freezer requires at least 63 mm of clearance for installation.
Limited Compatibility with Certain Motherboards
Some motherboards may be incompatible with the Liquid Freezer III Pro due to oversized SSD coolers in the M.2_1 slot. For affected motherboards, we provide a compatible M.2 cooler free of charge.
