Does anyone know the physical location of the KV7 motherboard temperature sensor?

    The KV7 has an oddity where the CPU temp is about three degrees lower
    than the system temp. I can't spot the board temperature sensor
    location. If anyone knows. I'd appreciate the info. RTM'd but no
    mention of the sensor location in the manual or the Abit website.

    I don't think this is a bug, or indeed anything that needs resolution
    - just my curiosity itching. All my other boards have always had a
    warmer CPU. There's a constant 3*C spread at idle (40*C CPU - 43*C
    board) is typical. They both track ambient air temp in lockstep.
    Under load, the board will heat up faster and further than the CPU
    (43*C CPU - 50*C board) is typical. I think this is due to having a
    huge slug of copper sitting on the CPU and no active cooling for the
    board sensor. The temperatures converge back to the 3*C spread.

    My prime suspicion is that it might be adjacent to the NB and under
    the umbrella of the NB heat sink/fan. The next candidate would be
    near the memory sticks. Or anywhere else that produces heat linked to
    CPU processing. A big problem is that I have no idea what it might
    look like. The tasks involved are CPU/RAM intensive, no graphics load
    and very little I/O to external SCSI drives.

    I don't think anything is amiss here, the system has been flawless
    since I built it a couple months ago - it was the easiest, most
    uneventful board install I've ever done. Curiosity is a harsh master.

    take a thin plastic tube & blow toward different parts of MoBo while
    watching temps; when drops fast for few deg.C, you located the area
    .... :)

    Now that's a simplistic, banal and almost trite response that borders
    on the verge of insulting!!!

    Made all the more intolerable by the fact that I didn't think of it
    meself :) Thanks for the idea - I'm sure it will put the curiosity
    beast at bay.

    thats How I spot mine 1cm2 close, than with magnifying glass I checked
    all smd stuff there & I spotted an smd resistor like unmarked element
    & measured it on my MoBo ... it was a approx.10k resistance (10k
    NTC).. yep, the onboard sensor ... :)
