    Pin-1 of the header. Be it fan, USB, CIR, HD_AUDIO1, IR1 etc etc

    If you were to look at the manual where it describes the individual headers(ex pg 34+35 of the oline manual), there is a "1" designating Pin-1 of most of the headers that correlates with this mystical white triangle.

    Please, refer to the manual section titled "Onboard Headers and Connectors". Your questions can mostly be answered in the manual. Clearly defined and enumerated in the manual.

    Thanks as always for the above info wardog,
    I have searched the manual -Which is always my first go-to.
    but it only noted the cpu fan header pin #.
    Can we say then that pin 1, no matter what fan header, is always Ground ?

    Attch'd is the screen shot from the manual
    You can see that the only pin numeration is on the CPU Fan connector
    The chassis and other fan headers do not have this pin layout marked.
    Hence the source of my queries

    Fan headers have the upright positioning key/tab that if properly attached to with the fans connector can not be mis-attached.

    Ok, I suppose someone might try to bend the friggin upright plastic outta the way ...............

    Just what the heck are you attempting(or have attempted if the case may be) that you are dead nut on this topic?

    Want to wire up a couple of cut fan connectors to fans with just leads, adding one into this MB /case
    To be sure about the correct wiring, that's all.

    That makes sense sturoc, and pin 1 is always ground for a fan header. For other connectors, like USB, pin 1 is not ground.

    Three pin and four pin fan headers are matched for pins 1 through 3, fortunately.
