Liquid Freezer III Pro 420

Multi Compatible All-in-One CPU Water Cooler

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.

The New P14 Pro Fans
The P14 Pro delivers quieter and more powerful performance at low speeds, with greater performance reserves under heavy 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

Premium-Class Radiator
The 38 mm radiator enhances heat dissipation and holds more liquid than standard 27 mm radiators, reducing heat buildup and improving temperature control.

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

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

Includes MX-6 Thermal Paste
Apply in a cross pattern—the cold plate spreads the paste evenly.

Two Control Options
Use the splitter cable for separate control of pump, VRM fan, and radiator fans, or sync them via a single PWM signal using the all-in-one cable.

Check Your Case for Compatibility
Requires at least 63 mm of clearance for installation.

Limited Compatibility with Certain Motherboards
Some boards may be incompatible due to oversized SSD coolers in the M.2_1 slot. A compatible M.2 cooler is provided free of charge for affected models.
