sensor identification

So I've got a question. I set up lm_sensors, and now I can see
temperatures, fan speeds, and voltages. But some of them are not
identified, or IDed with a low confidence. I see:

eben@pc:~$ sensors
it8716-isa-0290
Adapter: ISA adapter
VCore: +1.25 V (min = +0.00 V, max = +4.08 V)
+3.3V: +3.36 V (min = +0.00 V, max = +4.08 V)
+5V: +5.01 V (min = +0.00 V, max = +7.02 V)
+12V: +12.03 V (min = +0.00 V, max = +16.32 V)
-12V: -12.01 V (min = -0.00 V, max = -16.20 V)
V5SB: +5.01 V (min = +0.00 V, max = +7.10 V)
VBat: +3.06 V
CPU Fan: 1344 RPM (min = 0 RPM)
Cs front: 2472 RPM (min = 0 RPM)
Cs rear: 2755 RPM (min = 0 RPM)
CPU Temp: +29 C (low = -1 C, high = +127 C) sensor = diode
temp2: +36 C (low = -1 C, high = +127 C) sensor = thermistor
temp3: +25 C (low = -1 C, high = +127 C) sensor = thermistor
vid: +1.525 V

k8temp-pci-00c3
Adapter: PCI adapter
temp1: +28 C
temp3: +27 C

eben@pc:~$ cat /proc/acpi/thermal_zone/THRM/temperature
temperature: 40 C

The three fans and "CPU temp" I worked out myself. The fans I'm sure
about; I have a rheostat on the CPU fan, and the other two I unplugged
temporarily. "CPU temp" could be wrong, but it sure acts like the CPU.

But "temp3" from it8716-isa-0290 has been 25C for over 4 days (sampling
every 5 minutes), so I'm pretty sure it's bogus. Likewise, THRM has
been 40C for about 3 days. "temp1" and "temp3" from k8temp are shaped
like what I've been calling "CPU temp, but they're a couple degrees off,
sometimes higher, sometimes lower. Maybe sensors in the individual
cores?

Oh, here:

I added some sensors last night, and made mistakes in the logging
software (that's why there are gaps).
