I get:

# sensors
w83697hf-isa-0290
Adapter: ISA adapter
Algorithm: ISA algorithm
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:     +11.86 V  (min =  +0.97 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:     2700 RPM  (min =   -1 RPM, div = 2)
fan2:        0 RPM  (min = 168750 RPM, div = 2)
temp1: +280 C (high =  +400 C, hyst =  +120 C) sensor = thermistor

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,


Jean-Luc
