Description

Computer fan speed and lighting control structure

The present invention provides a speed and lighting control structure for a computer fan, in particular, a system that does not have to worry about directionality issues when a plurality of computer fans and lighting fan hub distributors are plugged into each other through a dual-plug connection line. At the same time, there are 8-PIN applicable signal terminals for controlling fan speed, lighting mode and power signals. Compared with the conventional 4-6PIN signal terminals, there are more electrical connectors, so fan speed and RGB can be accurately controlled. Light mode of light emitting diodes. Moreover, since the power terminal and the ground terminal share 4-PIN, it helps to provide large current power supply to the fan motor to reduce the gap between the predetermined speed and the actual speed, allowing the fan speed to be adjusted to the predetermined speed faster. The USB-C specification connector has the advantage of small size, which helps to design a ninety-degree turning structure between the electrical connector and the cable, making the internal wiring space of the computer more flexible.
