    Hello to all, I just need some help with my CPU Fan.

    I have a CPU Fan with a 4-pin connector, and what do each of them mean?

    I think the colors are yellow, red, blue, green and black.
    I know that the yellow and black wires are used for power, and the green for speed control.

    What are the red and blue used for?

    Pin Name Color
    1 GND black
    2 +12VDC yellow
    3 Sense green
    4 Control blue

    For some AMD cpu fans:
    Pin Name Color
    1 GND black
    2 +12VDC red
    3 Sense yellow
    4 Control blue

    Sense tells how fast the fan is going, control controls how fast it goes. Ground and +12V, are obviously, power.

    You talk about 4 pin fan connectors but then list 5 colors..

    I remember reading that in an old motherboard manual. Might I ask why exactly you wanted/needed to know? It sounds like you're going to try tampering with it.

    some motherboards only have 3 pins, in that case its perfectly fine in plugging a 4 pin plug into it, just the fan will run at max RPM

    I guess that makes sense, although in all my years building, repairing and upgrading computers, I've never come across a motherboard that didn't have a 4-pin CPU_FAN header.
