Blower fan 40*40*20mm
Compact in size, it is suitable for devices with limited space. Its fan blade design is unique, which can effectively generate strong wind pressure and quickly guide the airflow. It can efficiently dissipate heat in a narrow space, such as when used in mini PCS, projectors and other devices, ensuring that the devices maintain a relatively low temperature during operation.
