The BioniX F140 has the best airflow to noise ratio. The extreme silent 3-phase motor guarantees long gaming sessions without annoying noise. With a wide range of 200 to 1 800 RPM, the BioniX F140 is controllable with PWM to regulate the fan speed as needed. The optimised fan blade design ensures high pressure and high ventilation for your gaming case to get a higher airflow at lower noise generation. The 3-phase motor with low coil temperature quadruples the life span and we extend the warranty to 10 years.
