P6DGS CPU fan question

  1. Hi folks.

    I have a P6DGS with the latest BIOS from SM (2.12 I think, it shows up as
    R3.1 on the BIOS page). I am trying to get installed and there is one
    small problem in that the fan power connector for CPU #2 does not appear
    to be supplying any power to the fan. The fan on CPU #1 does run and if
    I connect the fan cable for CPU#2 to the fan power connector for CPU #1
    the fan on CPU #2 runs perfectly so I do not think there is nothing wrong
    with the fan on CPU #2 itself.

    The system when it is booting identifies both CPU's correctly so there is
    nothing fundamentally wrong with the behavior of the motherboard. The
    BIOS menu for peripherals shows the speed for Fan #1 as 4500 RPM (give or
    take) but the entries for Fan #2 *and* the thermal control fan are grayed
    out. I've looked in the manual and on SM's website but I can't find
    anything about turning on support for the second CPU fan. Is there a
    BIOS setting somewhere that will turn on the second fan?
