Heh, twenty years of using and supporting almost entirely MS products tends to 
brainwash one -- besides, we never stop learning, right?

Fairy nuff :-)

Ahh... I think you've possibly just hit the nail squarely on the head -- can 
you hear that?  That's the sound of me kicking myself, repeatedly.

wikkus at poochzilla:/etc> sensors -v
sensors version 2.8.7 with libsensors version 2.8.7

Sooo, I'm going to have to get down and dirty once more and do a little bit of

Good call, Jean. I checked what was being reported in the BIOS and was getting 
~29°C for the CPU and typically 5 or so °C less for the mobo.  I then went 
back into sensors.conf and tweaked a couple of things as suggested (temp1 to 
thermistor mode, temp2 to diode, ignore temp3) and got some more believable 

M/B Temp:    +30°C  (high =    +0°C, hyst =    +0°C)   sensor = thermistor
CPU Temp:  +25.0°C  (high =   +80°C, hyst =   +75°C)   sensor = PII/Celeron 

This is very positive stuff, although I think the labels for mobo and CPU need 
switching around.

Incidentally, I believe fan3 to be the PSU fan; still can't get anything from 
the CPU fan (it should be on fan0, as far as I can tell and is enabled with 
Asus' "Qcontrol" in BIOS), however, I'll not waste any more of your or my 
time 'til I've tried bringing the software more up to date.

It certainly did, many, many thanks.

Will report back once I've had a chance to upgrade.

Kind regards, Rik.
