The FW81 is a high quality, standard sized 80mm fan designed for optimal performance with low noise profile. It 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. Powered via PWM 4pin connector, the FW81's speed can be adjusted by supported motherboard or fan controllers to be used for silent running builds or for cooling a high performance machine.

• Mixed fan blade design for noise reduction
• PWM design allows 1200 ~ 3000rpm fan speed control by motherboard
• High efficiency system thermal solution
