Main product

Overview


Outstanding cooling performance through liquid cooling. ARCTIC's Premium Liquid Freezer range offers impressively high performance at moderate prices without the complexity of conventional CPU water coolers. Completely maintenance-free, the all-in-one cooler with various models for smaller and larger cases covers all the most important current CPU sockets.




At-a-glance


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

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

  • Please note that the Liquid Freezer requires at least 63 mm of clearance for installation

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

  • PWM-controlled fan lowers the voltage regulator temperature, ensuring stable performance.

  • Reinforced EPDM tubing with braided sheathing for increased durabilit

  • Shifts the cold plate to the CPU hotspot for more efficient heat transfer.

  • Simply apply in a cross pattern—the water pump’s cold plate distributes the paste evenly

  • 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.

  • The P12 Pro unleashes its full potential: quieter and more powerful at low speeds, with greater performance reserves under load—for maximum cooling without compromise.
