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.

Thanks for the idea - I'm sure it will put the curiosity
