Tuuletin Fractal Design Venturi HP-14 PWM

The Fractal Design Venturi HP-14 PWM is a 140 mm high-flow case fan engineered for low-restriction airflow environments such as PC cases, low-density heatsinks and radiators. It operates from 400 to 1500 RPM, delivers up to 78.1 CFM of airflow and up to 1.94 mmH2O static pressure while maintaining low noise levels (10 dB at low speed, 30.1 dB at high speed). The fan is finished in black and grey, powered by 12 V and built from glass-fiber reinforced thermoplastic for long-term durability.

Advantages

The Venturi HP-14 PWM combines fluid-dynamic bearing (FDB) technology and a counter-balanced magnet to ensure quiet operation and extended bearing life. Aerodynamically shaped thin stator struts, blade notches and trip-wire technology reduce turbulence and humming, improving acoustic performance. Integrated solid rubber vibration-dampening corners reduce transfer of vibration to the chassis, and the robust glass-fiber reinforced construction increases structural stability under continuous use. A low-speed adapter is included to lower RPMs without a fan controller.

Key specifications

How to use

Mount the Venturi HP-14 PWM using the included vibration-dampening corners or screws to match your case or cooler mounting pattern. For standard 140 mm mounts use the 125 mm corner spacing; if your cooler requires 120 mm spacing, fit the supplied adapter corners for 105 mm screw spacing. Connect the fan to a PWM-capable 4-pin header on the motherboard to allow automatic speed control, or use the low-speed adapter to reduce power and noise when manual throttling is preferred. Ensure the fan airflow direction matches your intended intake or exhaust configuration.

Recommendations

Use the PWM header for dynamic control to balance cooling and noise. Clean the fan and surrounding dust filters periodically to maintain airflow and acoustic performance; avoid obstructing the intake or exhaust paths for best results.
