80 mm, 1200 - 2800 rpm, 4 pin PWM, 12V DC, 74g FQ81 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. FQ81 uses the award-wining fan blade design from AP123 with three distinct shape and sizes to create uneven airflow which is capable of reducing noise frequency effectively compared to traditional fan designs. These features not only improve ventilation but also decrease operating noise.
