Hi,
I have a new Intel DG31PR motherboard with an Intel 7200 Core 2 Duo
processor reporting what look like very high temperatures. Running
Debian GNU/Linux Testing.
Software:
Kernel: Linux XXX 2.6.26-1-686 #1 SMP Thu Aug 28 12:00:54 UTC 2008 i686
GNU/Linux
libsensors3 1:2.10.7-1
libsensors4 1:3.0.2-1+b2
lm-sensors 1:3.0.2-1+b2
sensors-detect seems to find the sensors fine (transcript at bottom).
However now I find that some of the temperatures seem to be
unreasonably high. Please see Sys Temp (76.0C) and Aux Temp (127.0C)
in the sensors output under.
Is this normal/expected? If not, any solution for this issue? I'd be
glad to provide any other information required.
Regards,
-- Raju

127 degrees C typically means that no thermal sensor is connected to
that input. So you can ignore this input.
76 degrees C is admittedly very high, but then again it depends what it
is measuring. Don't trust the default labels which may or may not apply
to your motherboard. You should compare with what the BIOS says. Also
look at the motherboard documentation, in my experience Intel board
have a good description of where the thermal sensors are located.
If the temp1 value never changes, you may try changing the sensor type
and see if you get better values. But the BIOS should have set the
proper type for you already.

According to coretemp your CPU isn't too hot, so you really don't have
to worry for the CPU.

Thanks, that's what I suspected, glad to have it confirmed.

The BIOS reports it as "Motherboard Temperature". It keeps slowly
varying in the 72-76 degrees C range.
I'm afraid hardware isn't really my domain, so even though I do have the
document it doesn't make much sense to me. What I do gather from from
the technical specs
(http://download.intel.com/support/motherboards/desktop/dg31pr/sb/e14051001us.pdf)
is that there are thermal sensors in the CPU(s), the I/O Controller Hub
(ICH7) and the Graphics and Memory Controller Hub (GMCH). If I
correlate that information with the sensors-detect output and eliminate
the core temperatures, it seems that the 76 degrees C is in the ICH7
(though I could be totally wrong).
In any case, from experience, is a temperature of 76C in the ICH or the
GMCH a cause of concern? If this is in the normal range for
motherboard temperatures I'll stop worrying about my system running hot
right now :) If it looks high, I'll ask my hardware supplier to check
the board out for faults. All advice appreciated.

OK, so same as what lm-sensors report. So it has to be correct.

Not sure how you "correlate", but I'd rather say 76 degrees C is the
GMCH and 35 degrees C is the ICH. Rationale: the GMCH has a heatsink
while the ICH doesn't.

From the motherboard documentation: "The minimum thermal reporting
threshold for the GMCH is 66 °C. The GMCH thermal sensor will report 66
°C until the temperature rises above this point." If you want my
opinion, if the sensor they use doesn't bother reporting values below
66 degrees C, this suggests that the normal operating temperature is
more than that. So 76 degrees C would be considered OK.
Maybe you can google for other thermal reports for this motherboard or
similar ones (with the same GMCH). If other users have the same kind of
temperature reported, that must be OK.
(My personal thoughts are that running pieces of hardware at the high
temperatures we see these days is insane but that's a different story.)
