Hi,

submitting a sensors.conf file for a Jetway NC92-330-LF motherboard

Done, thanks for your contribution:
http://www.lm-sensors.org/wiki/Configurations/Jetway/NC92-330-LF

Note: you should really be able to tell which is the CPU temperature
sensor by putting significant load on the system and watching which
temperature value raises highest and fastest.

Re: [lm-sensors] Jetway NC92-330-LF motherboard sensors.conf

[Maciej Żenczykowski]

Fair enough, but the intel atom 330 chip is only 8W TDP (passive
cooling, although using the exhaust heat from the northbridge for
cooling) and the northbridge chipset is ~20W TDP (active cooling).  As
such it's not clear exactly what to expect to get hotter faster.
They're marked the way I believe the BIOS marks them, but on an idle
machine with plenty of cooling:

Core 0:      +40.0°C  (crit = +95.0°C)
Core 1:      +41.0°C  (crit = +95.0°C)
Core 2:      +42.0°C  (crit = +95.0°C)
Core 3:      +41.0°C  (crit = +95.0°C)

CPUFAN:     1920 RPM
SYSFAN1:    3667 RPM
SYSFAN2:    2008 RPM
?CPU Temp:   +31.0°C  (high = +85.0°C, hyst = +81.0°C)
?Sys Temp:   +41.0°C  (high = +85.0°C, hyst = +81.0°C)
???? Temp:   +47.0°C  (high = +70.0°C, hyst = +68.0°C)

# cat /proc/acpi/thermal_zone/THRM/temperature
temperature:             31 C

Unfortunately the core temps may or may not be correct (they may need
an offset of +-X degrees, since it's not clear what TjMax actually is
for an atom 330, and I'm 'kind of' guessing it to be 95), and the cpu
temp being lower than the sys temp actually makes some sense...

The last temperature isn't even shown by the BIOS, but does seem to
show a kind of reasonable value (maybe it's the NB?)...

I'm guessing that the CPU does actually run cooler than the
northbridge - it's just a tad counter-intuitive.

(In case that wasn't clear, the thing marked CPUFAN in the BIOS and in
the config is actually on the northbridge, and the exhaust from the
northbridge blows over the cpu)

Re: [lm-sensors] Jetway NC92-330-LF motherboard sensors.conf

Running mprime295-linux64 test 2 = In-place large FFTs (maximum heat
and power consumption, some RAM
tested) with 4 threads.

Core 0:      +55.0°C  (crit = +95.0°C)
Core 1:      +58.0°C  (crit = +95.0°C)
Core 2:      +58.0°C  (crit = +95.0°C)
Core 3:      +55.0°C  (crit = +95.0°C)
?CPU Temp:   +47.0°C  (high = +85.0°C, hyst = +81.0°C)
?Sys Temp:   +43.0°C  (high = +85.0°C, hyst = +81.0°C)
???? Temp:   +47.0°C  (high = +70.0°C, hyst = +68.0°C)

ACPI THRM temperature:             47 C [so this is probably just CPU Temp]

So '?CPU Temp' is probably indeed CPU Temp, but the other two are
still unclear (especially the third one, which does oscillate a
little, seen 45-48).

The Core Temps do seem to be consistently about ~10 C higher than CPU
Temp, which suggest that TjMax is probably closer to 90 C [instead of
the assumed 95 C].  Since usually core temps are about 5 C higher than
cpu case temp, assuming that that is indeed what is being measured
here.  Which also is in compliance with the thermal spec of an atom
330 being 85.2C [
http://processorfinder.intel.com/details.aspx?sSpec=SLG9Y ] (+~5C case
max to junction max gives a 90C TjMax).  But it's really all just
guess-work...

Unfortunately my setup has rather good cooling (ran into issues with
the 2 HDDs overheating and opened up the case and added an extra huge
fan).  And as I don't currently have physical access to it (it's on
the other side of the pond) I'm not willing to dial it down.

Anyway... to actually include some useful content in this email.  How
are we going to proceed with the atom coretemp patch? [forward ported
from http://bugzilla.kernel.org/show_bug.cgi?id\x11161 ]

Cheers,
Maciej
