The New P14 Pro Fans

Bearing: Fluid Dynamic Bearing
Static Pressure: 5.2 mmH2O
Airflow: 110 cfm 
 
 
 
 
 
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.
