Arctic Liquid Freezer III Pro 420 AIO CPU Liquid Cooler (ACFRE00181A)

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.

Speed: 400—2500 rpm

Bearing: Fluid Dynamic Bearing

Static Pressure: 5.2 mmH2O

Airflow: 110 cfm | 186 m³/h

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

Optimized contact pressure distribution for longer CPU lifespan and improved heat dissipation.

Integrated Cable Management

Fan cables integrated into the sleeving simplify installation and minimize cable clutter.

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 synchronized 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.
