I get:

temp2: +345.0 C (high = +1200 C, hyst = +1200 C) sensor = thermistor


As you can see, the temperatures are obviously wrong, and what are they
for (CPU, motherboard)?

Is there anything I can do to help debug the problem? Please let me know
(I know C and can patch).

Many thanks in advance,

Update userspace tools to 2.8.4. Also check sensors.conf and uncomment
all settings for your chip, there are no more builtin defaults...

May thanks to all who responded: the temperatures indeed needed being
divided by 10, and it looks like lm_sensors 2.8.4 fixed it as shipped:

$ sensors
w83697hf-isa-0290
Adapter: ISA adapter
VCore:     +1.62 V  (min =  +0.06 V, max =  +0.03 V)
+3.3V:     +3.31 V  (min =  +0.14 V, max =  +0.00 V)
+5V:       +5.08 V  (min =  +0.11 V, max =  +0.00 V)
+12V:     +11.92 V  (min =  +1.22 V, max =  +9.73 V)
- -12V:      +1.13 V  (min =  -4.22 V, max =  -4.38 V)
- -5V:       +2.09 V  (min =  -7.71 V, max =  -7.71 V)
V5SB:      +5.62 V  (min =  +5.43 V, max =  +0.27 V)
VBat:      +0.06 V  (min =  +0.03 V, max =  +1.28 V)
fan1:     2721 RPM  (min =   -1 RPM, div = 2)
fan2:        0 RPM  (min = 168750 RPM, div = 2)
temp1: +28°C (high =+40°C, hyst = +12°C) sensor = thermistor
temp2: +34.0°C (high = +120°C, hyst = +120°C) sensor = thermistor

The only thing I am missing now is the RPMs of fan #2 (available in the
BIOS). Any ideas?

Thanks again!
