wrong cpu temp

wrong cpu temp

[Victor G. Marimon]

Hi, now i'm running sensors but shows wrong temperature.

    with 'modprobe it87' show:
it87-isa-0290
Adapter: ISA adapter
Algorithm: ISA algorithm
VCore 1:   +1.69 V  (min =  +1.53 V, max =  +1.87 V)
VCore 2:   +1.31 V  (min =  +2.25 V, max =  +2.75 V)   ALARM
+3.3V:     +6.78 V  (min =  +2.96 V, max =  +3.60 V)   ALARM
+5V:       +5.04 V  (min =  +4.50 V, max =  +5.48 V)
+12V:     +12.40 V  (min = +11.36 V, max = +13.80 V)
-12V:     -12.56 V  (min = -15.86 V, max = -13.40 V)   ALARM
-5V:       -8.05 V  (min = -10.13 V, max =  -9.44 V)   ALARM
Stdby:     +5.11 V  (min =  +4.50 V, max =  +5.48 V)
VBat:      +0.00 V
fan1:     4411 RPM  (min = 3000 RPM, div = 2)
fan2:     3750 RPM  (min = 3000 RPM, div = 2)
fan3:        0 RPM  (min = 3000 RPM, div = 2)          ALARM
Temp1/MB:    +40?C  (min =  +20?C, max =  +60?C)
Temp2/CPU:   +89?C  (min =  +20?C, max =  +60?C) ALARM
Temp3:       -55?C  (min =  +20?C, max =  +60?C)


and with 'modprobe it87 temp_type=0x290' tha i think is the correct parameter for my it87. show negative number

it87-isa-0290
Adapter: ISA adapter
Algorithm: ISA algorithm
VCore 1:   +1.69 V  (min =  +1.53 V, max =  +1.87 V)

+3.3V:     +6.78 V  (min =  +2.96 V, max =  +3.60 V)   ALARM
+5V:       +5.02 V  (min =  +4.50 V, max =  +5.48 V)
+12V:     +12.48 V  (min = +11.36 V, max = +13.80 V)
-12V:     -10.56 V  (min = -15.86 V, max = -13.40 V)   ALARM
-5V:       -7.84 V  (min = -10.13 V, max =  -9.44 V)   ALARM
Stdby:     +5.11 V  (min =  +4.50 V, max =  +5.48 V)
VBat:      +0.00 V
fan1:     4411 RPM  (min = 3000 RPM, div = 2)
fan2:     3750 RPM  (min = 3000 RPM, div = 2)
fan3:        0 RPM  (min = 3000 RPM, div = 2)          ALARM
Temp1/MB:    +40?C  (min =  +20?C, max =  +60?C)
Temp2/CPU:   -55?C  (min =  +20?C, max =  +60?C)
Temp3:       -55?C  (min =  +20?C, max =  +60?C)



the temp of motherboard is well, the mb is a gigabyte GA-7VAXP-A Ultra with KT400A and vt8235 with it8705f chip.

No, it isn't. You should have read the docs... Try temp_type=0x1c.

        but i have it8705f and in the docs is 0x290. i try it and wrong too.

[lm-sensors] Wrong CPU Temp

[Paul Smith]

Dear All,

In the output below, the value

CPU Temp:     -2.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = transistor

seems unlikely:

$ sensors
it8712-isa-0290
Adapter: ISA adapter
VCore 1:     +1.28 V  (min =  +0.00 V, max =  +4.08 V)

+3.3V:       +3.38 V  (min =  +0.00 V, max =  +4.08 V)
+5V:         +6.85 V  (min =  +0.00 V, max =  +6.85 V)   ALARM
+12V:       +11.84 V  (min =  +0.00 V, max = +16.32 V)
-12V:       -13.86 V  (min = -27.36 V, max =  +3.93 V)

fan3:          0 RPM  (min =    0 RPM, div = 8)
M/B Temp:    -55.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = transistor
CPU Temp:     -2.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = transistor
Temp3:       +47.0°C  (low  = +127.0°C, high = +90.0°C)  sensor = thermal diode
cpu0_vid:   +1.350 V

My motherboard is a GigaBite GA-81945PL-G, the processor is an Intel
Dual Core, and the operating system is Fedora 9.

Any ideas?

Thanks in advance,

Paul

Typical of Gigabyte boards. They put two Ethernet chips, 2 USB
controllers, Firewire, two Serial ATA controllers, etc. on the board,
but omit the thermistor for motherboard temperature to save a few
cents. Go figure... My own board (Gigabyte K8V Ultra-939) says:

temp1:       +25.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = disabled
temp2:       -55.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = disabled
temp3:       +47.0°C  (low  = +10.0°C, high = +51.0°C)  sensor = thermal diode

And temp1 never changes. So, same as yours: temp3 is the CPU
temperature, and temp1 and temp2 can be ignored (and even disabled).
The relevant part of my configuration file is:

### Temperatures

   # Gigabyte confirmed that there is no system temperature sensor on this
   # motherboard. This is really disappointing, as the board is otherwise
   # full featured.

   ignore temp1
   ignore temp2
   label  temp3  "CPU Temp"

   set temp1_type 0
   set temp2_type 0

   # The CPU temperature was seen from 34 to 48 degrees C so far.
   set temp3_min  10
   set temp3_max  51

Hope that helps,

Thanks, Jean. Now I know (from you) that temp3, in my case,
corresponds to the CPU temperature.
