Subject: 2.6.16-rc5: unreasonable temperature reported by w83627thf-isa-0290

Hi folks,

Configuring a barebone (Aopen MZ915-M) I tried the sensors stuff
today. After running sensors-detect this is what sensors reports:

w83627thf-isa-0290
Adapter: ISA adapter
VCore: +1.36 V (min = +1.94 V, max = +1.94 V) ALARM
+12V: +12.28 V (min = +10.82 V, max = +13.19 V)
+3.3V: +3.18 V (min = +3.14 V, max = +3.47 V)
+5V: +4.93 V (min = +4.75 V, max = +5.25 V)
-12V: -12.11 V (min = -13.18 V, max = -10.80 V)
V5SB: +5.05 V (min = +4.76 V, max = +5.24 V)
VBat: +3.10 V (min = +2.40 V, max = +3.60 V)
fan1: 0 RPM (min = 664 RPM, div = 8) ALARM
CPU Fan: 0 RPM (min = 664 RPM, div = 8) ALARM
fan3: 0 RPM (min = 664 RPM, div = 8) ALARM
M/B Temp: +7 C (high = +45 C, hyst = +101 C) sensor = diode
CPU Temp: -5.5 C (high = +80 C, hyst = +75 C) sensor = diode
temp3: +7.5 C (high = +80 C, hyst = +75 C) sensor = diode (beep)
alarms:
beep_enable:
Sound alarm enabled

The voltage values seem to be the same as the bios displays.
The min/max values of VCore doesn't seem right to me.

M/B and CPU temperatures are unreasonable. Not to mention
the CPU fan. It is set to full speed in the bios.

Any ideas? Any help would be highly appreciated.


Regards

Harri

You can just change these values to something more suitable. Edit
/etc/sensors.conf, seek to the w83627thf-* section, edit the "set
in0_min" and "set in0_max" lines.

Does the BIOS report any speed for that fan? If so, what is the value?

The temperature values are admittedly strange. What temperature values
does the BIOS report, if any?

Either your W83627THF chip needs some additional configuration (such as a
different thermal sensor type selection), or you have another chip on
the board handling fans and tempeartures.

Please provide the full output of sensors-detect. Also, let us know which
version of lm_sensors you are using (sensors -v).

Note that you may want to follow-up on this on the lm-sensors list [1]
rather than the LKML, which isn't really the place for user-space
configuration issues.
