I thought knowing the temperatures would be handy, and anyway, it's a
useful diagnostic and it's supposed to work. To configure it, run
sensors-detect. It worked with just pressing enter on all questions. You
said before you had a GA-K8NF9-Ultra, according to the manual, the
differences are nforce4-ultra chipset instead of nforce4-4X, and a third
fan header next to the big power connector. /etc/init.d/lm_sensors
restart, and things are off the ground. Kudos to the sensors team and
SUSE.

Now the tricky bit is working out to which chip inputs Gigabyte has
connected the various fan, thermistor and voltage lines. For the latter
two, it's also important to know the value of various resistors used.
For the truely dedicated, it's time for a meter and PCB track tracing...
Otherwise, guess values which were recommended in the chip's (ITE
IT7812?) reference application note...

The default values from sensors are useless. Also, I had trouble getting
it to load the correct lines belonging to the chip section in
/etc/sensors.conf, so it's best to clear out the file (keep some
comments) and only put the necessary lines into it. So far, I have

That's work in progress. You'll want to edit the fan3 settings. (Wonder
whether it's possible to solder the missing fan header on the K8NF-9...)
The BIOS display of CPU temp is 2°C lower for me, at around 30°C. As the
BIOS doesn't display actual voltages, one would have to compare with a
voltmeter. I don't know what Vcore1 is, but it looks dubious:

  VCore1:    +1.42 V  (min =  +1.20 V, max =  +1.81 V)

The BIOS summarises Vcore1 + 2 under Vcore, so one doesn't even know
what numbers one is supposed to get from sensors.

All in all, these mobos don't have a very extensive monitoring
capability. If I find out more, I'll post it.

Btw the chipset heatsink runs at about 70°C - is that
normal/desirable/fixable?

HTH + Thanks,

Volker
