    I just bought the Gigabyte GA-K8NS Ultra-939 along with an Athlon 64
    3200+ in a retail box (standard AMD fan). When I hooked everything up,
    the CPU fan stopped running while I was setting up the inital bios
    settings. The CPU fan fail alarm immediately went off. I then turned
    the smart fan control off to avoid frying my CPU and everything appears
    to work. My question is according to the manual (yes I did read it) the
    fan speed is reduced if the temperature is lower then 40 c. I assume
    reduce means it is still running not stopped. Is this normal? Needless
    to say, I didn't wait for the cpu to haet up to see if it start running
    again. Other than that, the board seems fine. I would still like to use
    this feature if it actually works.

    I've run into this too, only I use a Zalman CPU cooler on a
    potentiometer. Zalman warns of this possibly happening if you have the
    pot set for the lowest RPM setting for the fan. Disabling the smart fan
    control seems to get rid of the problem, although so will a vulcan nerve
    pinch as soon as you hear the alarm. I've noticed that this only seems
    to occur from a cold bootup too, but not on a warm reset of my system.

    I got a reply from Gigabyte support (surprised how fast they answered).
    In broken english, they said this was normal. They said that you can
    either use the smart fan control or the fail CPU fan alarm but not both
    at the same time. I appreciate everyones responses. I found it
    unsettling to wait for the fan to turn on during a cold boot.
