The most striking feature of the bionic Noiseblocker fans is the unique shape of the blades, which makes the air noise itself much quieter. At the same time fans help focus airflow. This enables a more directional and efficient airflow style, offering benefits depending on where they are used and the components with which they are paired (directional air transport, air flow management, water cooling, etc.). A total of seven digitally addressable RGB LEDs are installed, discreetly illuminated transparent fan blades. Thanks to the distributed 3-pin connector (5VDG) fans can be easily connected directly to the properly equipped main board or controller. Lighting can be controlled with ASUS Aura Sync, MSI Mystic Light or Gigabyte RGB Fusion.
