That was a possibility I wondered about too.  Mark-I fingertips
confirm that the heatsink is barely warm.

I think the Asus A7V's CPU sensor just needs a lookup table to convert
it to real temperature units. (Curt Sampson) writes:

Although netbsd probably doesn't go through the bios to read the temp.

A few of the authors of m$-based temperature monitoring programs
mentioned that they have to add/subtract a fixed number of degrees
from the CPU sensor to get the right answer.  This doesn't give me a
"warm fuzzy" feeling about the care used in designing this hardware.

I'm pretty sure the first is the mobo temp and the second is the CPU
