Gentle Typhoon 120 mm High Speed Series are optimised for high speed as well as high airflow. An implemented ring connects the fan blades creating characteristics similar to 38mm thick fans, while running at a quieter noise level. By employing a large fan motor, little fluctuation in rotation torque has been achieved. Furthermore, a vibration absorbing structure has been integrated to further help reduce the noise level. Optimized for High Airflow Forceful airflow is created & guided in a linear fashion thanks to the implemented stabilising ring. By using this powerful design the fans are able to generate high pressure to overcome & handle high resistance such as when being used with a duct or coolers with dense fin structure. Vibration Reduction Structure By employing a large fan motor, little fluctuation in rotation torque has been achieved. Furthermore, an anti-vibration absorbing structure has been integrated to further reduce the noise level. This combination greatly reduces the transfer of vibration from the motor to the fan chassis.
