Integrated design, simple and quiet, can effectively reduce the installation and line management problems,It can effectively reduce the loss of air volume and air pressure, and create a strong three-dimensional air duct for the chassis. The fan blade has a guide groove, and the arc surface of the fan blade is processed to increase the air intake efficiency, reduce the intake noise and effectively improve the air pressure. Good compatibility, not only can the chassis be used, but also can be compatible with CPU Liquid Cooler, providing strong thermal protection for the chassis and CPU.
