Ventilator Fractal Design Venturi HP-12 PWM

The Fractal Design Venturi HP-12 PWM is a 120 mm case fan engineered for high airflow in low-restriction environments such as computer chassis and low-density heatsinks or radiators. Operating at 12 V with a rotational speed range of 400–1800 RPM, it delivers up to 104.3 m³/h airflow and a maximum static pressure of 2.3 mmH2O. The fan combines a sturdy glass-fiber reinforced thermoplastic construction with a grey and black finish and is intended to provide efficient cooling with low audible noise.

Advantages

The Venturi HP-12 PWM uses a true fluid dynamic bearing (FDB) for quiet operation and long service life, and its motor includes a counter-balanced magnet to reduce axial bearing load. Aerodynamically optimised blades, thin stator struts and blade notches reduce turbulence and humming, while integrated trip-wire technology creates a micro-turbulent layer that improves stability and noise performance. The fan's dense construction and integrated vibration-dampening corners further reduce vibration and increase durability.

How to use

Install the Venturi HP-12 PWM into a standard 120 mm mounting location in your computer case or on compatible cooling hardware, aligning the airflow direction as required by your system's airflow design. Connect the fan to a PWM-capable header on the motherboard or to an appropriate fan controller using the supplied cable. Use the motherboard BIOS or fan control software to configure PWM curves for the desired balance of cooling performance and noise.

Recommendations

For best results, place the fan in airflow positions that minimise obstructions and maintain a low-restriction path. Use PWM control to limit maximum speed when full airflow is not required; regular cleaning of dust from blades and heat-exchange surfaces will help preserve airflow and prolong fan life.
