Ventoinha NZXT F140q 140mm preto Quiet Airflow

The NZXT F140Q 140mm Quiet Airflow PWM case fan delivers focused, high-volume airflow with low noise for desktop PC cooling. Featuring nine sickle-style blades, a chamfered frame and a minimal blade-to-frame gap, the fan is optimized to push air deep into the chassis. It uses a fluid dynamic bearing rated for a long service life and supports PWM speed control to adapt fan RPM to system temperature.

Advantages

Optimized blade geometry and a reduced blade-to-frame gap increase airflow efficiency while maintaining low acoustic output. The chamfered frame concentrates airflow toward internal components for more effective cooling. Fluid dynamic bearings provide quiet operation and extended durability, and PWM control allows automatic speed adjustment for a balance of cooling and noise.

Suitable for

• Case intake or exhaust in mid-tower and full-tower PC builds
• Cooling for CPU air-cooling and GPU-ventilation assistance
• Systems where low noise and long bearing life are desired

Key specifications

• Size: 140 mm
• Speed range: 500–1500 RPM (PWM)
• Maximum airflow: 102.9 CFM
• Noise level: 29.8 dB

• Manufacturer: NZXT, MPN RF-Q14SF-B2, EAN 5056547204338

How to use

Install the fan in a standard 140 mm mounting position in your PC case, aligning airflow direction toward the desired intake or exhaust. Connect the fan to a motherboard PWM header or a compatible fan controller to enable automatic speed regulation. Secure the fan using the supplied screws or mounting hardware and route the cable to avoid contact with the blades.

Recommendations

For best results, use the NZXT F140Q on cases with clear airflow paths (unobstructed intake and exhaust). Place as intake for positive pressure or as exhaust to aid heat removal; maintain regular dust cleaning to preserve airflow and bearing life.
