Well I discovered today that
this is not the ADT7475 driver but it's more general problem.

Look at these:

it8716-isa-0290
Adapter: ISA adapter
VCore:       +1.22 V  (min =  +4.08 V, max =  +4.08 V)
VDDR:        +3.20 V  (min =  +4.08 V, max =  +4.08 V)
+3.3V:       +0.00 V  (min =  +4.08 V, max =  +4.08 V)
+5V:         +4.76 V  (min =  +6.85 V, max =  +6.85 V)
+12V:       +11.46 V  (min = +16.32 V, max = +16.32 V)
in5:         +0.00 V  (min =  +4.08 V, max =  +4.08 V)
in6:         +0.00 V  (min =  +4.08 V, max =  +4.08 V)
5VSB:        +4.70 V  (min =  +6.85 V, max =  +6.85 V)
VBat:        +2.98 V
CPU Fan:    1666 RPM  (min = 1400 RPM)
Chasis 1:   675000 RPM  (min =  900 RPM)
CPU Temp:    +49.0°C  (low  = +10.0°C, high = +60.0°C)  sensor = thermal diode
MB Temp:     +39.0°C  (low  = +10.0°C, high = +45.0°C)  sensor = transistor
cpu0_vid:   +1.325 V

ADT7475-i2c-1-2e
Adapter: SMBus nForce2 adapter at 1c40
vccp:        +0.00 V  (min =  +0.00 V, max =  +2.99 V)   ALARM
vcc:         +3.27 V  (min =  +0.00 V, max =  +4.28 V)
Chasis 2:   180000 RPM  (min =  900 RPM)
fan2:          0 RPM  (min =    0 RPM)
fan3:          0 RPM  (min =    0 RPM)
fan4:          0 RPM  (min =    0 RPM)
remote1:       FAULT  (low  = -63.0°C, high = +191.0°C)  ALARM
local:       +42.8°C  (low  = +10.0°C, high = +45.0°C)
remote2:       FAULT  (low  = -63.0°C, high = +191.0°C)  ALARM

so both readings from it8716 and ADT7475 are wrong.What is funny that
the CPU Fan reading is always ok - while for it8716 there are chances
that issuing servera 'sensors' command will bring at least (one chances of five ratio) some good result
(in random order) the ADT7475 shows 'always' wrong value.
Tested on Debian using:
libsensors3                          2.10.5-5
libsensors4                         3.0.1-1
lm-sensors                          3.0.1-1

If I can help please let me know.

Best regards
Artur
