FQ Series     FQ91

■ PWM design allows 1000~2500rpm fan speed control by motherboard

■ Optimum airflow, pressure and extremely silent performance

■ Innovative blade design focuses airflow with maximum efficiency

■ Air-inlet with optimized aerodynamic design reduces noisy air turbulence

■ Anti-vibration rubber pads included for additional noise dampening

         FQ91 represents SilverStone’s pursuit of a design that balances performance and tranquility. Its included PWM module allows motherboard to control fan speed and regulate the temperature inside your chassis with optimal efficiency. It has custom designed dual fan blades for increased air pressure performance without additional noise. These features not only improve ventilation but also decrease operating noise.
