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.

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.

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.

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.
