Wiring a 4 pin fan direct to 1. DC Components. Sammycoup, that color system is NOT common, so the colors alone may not help. But IF it has a standard 4 pin female fan connector on the end of those wires, we can figure it out. A standard connector has on one side of it two ridges just outside the first and third pins, with the fourth pin beyond the one ridge. When this is plugged into a male mobo fan header, that header has a plastic tongue sticking up beside Pins 1 3, and those ridges must fit outside the tongue. That way you can only plug the fan in one way. Now, look again at the connector. The hole on the fan connector at one end that is OUTSIDE the ridges is Pin 4. Pin 1 starts at the other end, just inside one of the ridges. Ignoring the colors for a moment, the pins hole have these functions Pin 1 Ground normally BlackPin 2 1. VDC fixed voltage on a 4 pin fan system normally Yellow, sometimes RedPin 3 Speed pulse signals from motor to mobo normally Green, sometimes YellowPin 4 outside the ridges PWM signal normally Blue.
