14 cm Computer Case Fan Fractal Design Venturi HF-14 — 140 mm, 1200 RPM, 118.2 cfm, FDB, 12 V, 25 mm thickness

Fractal Design Venturi HF-14 is a 140 mm computer case fan optimized for low-restriction airflow environments. With a maximum speed of 1200 RPM and a maximum airflow of 118.2 cfm (200.8 m³/h), the fan uses a Fluid Dynamic Bearing (FDB) and a robust motor to provide reliable, quiet operation at 12 V. The HF-14 is built from glass-fiber reinforced thermoplastic and measures 140 × 140 × 25 mm; it is available in white, grey or black.

Advantages

The HF-14 combines high airflow and low noise through aerodynamic blade geometry, thin stator struts and strategically placed blade notches that reduce turbulence and humming. True FDB bearings and a counter-balanced magnet extend lifespan and minimize friction. Integrated vibration-dampening rubber corners and sturdy glass-fiber reinforced construction reduce vibration and improve durability. A low-speed adapter allows reduced fan speed without an external controller, and the motor maintains stable RPM under load.

Suitable for

• Computer case ventilation with low-restriction airflow paths
• Low-density heatsinks and radiators where high flow at low resistance is required
• Systems requiring quiet, long-life fans for continuous operation
• Installations where 140 mm fans must fit 120 mm mounts (using included rubber corners)

How to use

Mount the fan in the desired orientation using the supplied vibration-dampening rubber corners for either 140 mm or 120 mm screw spacing as needed. Connect the fan to a compatible 12 V header or controller, and use the included low-speed adapter if reduced RPM is desired without a fan controller. Ensure airflow direction matches system cooling requirements and avoid obstructing intake or exhaust paths for optimal performance.

Usage recommendations

For best results, install the HF-14 in low-restriction locations such as case intakes or radiators with minimal fin density. Use the 120 mm compatible rubber corners when mounting to CPU coolers with 105 mm screw spacing. Periodically check for dust buildup and clean the fan to maintain airflow and quiet operation.
