Features: Compared with the RGB fans that emit light from the border, the FR-502 adopts the axial light-emitting mode, no need to reduce the size of the fan blade so as to achieve large air volume heat dissipation. After the fan is energized, it first automatically cycles in a single color and then enters the cyclic color changing mode. The FR-502 frame is designed with four reinforcing ribs to strengthen the structure, which can effectively protect the fan from deformation. Built-in hydraulic bearings use closed design to significantly increase service life. FR-502 provides a 3PIN to 4PIN adapter cable, which can realize direct power supplying and power supplying interface serial connection function, can connect multiple fans by using 4PIN interface of one power supply.
