1903 confuses thermal controls
 

So far, I haven't found any real problems with 1903 except
one. If the machine wakes from Sleep, the fans all rev up
to max but then stay set that way until I reboot. This
does NOT happen if the machine emerges from hibernation
mode. Has anybody else seen this behavior?

Any BIOS (or BMC) upgrades available for the machine?

Unfortunately, no. The machine is an antique.

What software runs your fans ?

There is a BIOS version of fan auto control.
It programs the fans at startup.

It is the responsibility of the BIOS to restore
those registers, when the system comes up from
hibernation.

It's possible the CPU could use CoreTemp to
control a PWM signal. But then it might not
be controlling all the fans (like a cabinet
cooling fan), as it wouldn't know how to measure
the cabinet temperature.

Even if you were to use Speedfan, it might not
correctly identify all the control devices on
the various buses. You might need to do that
kind of snooping, to try to understand how
fan control is done on your machine.

I'll try speedfan. Unfortunately, when I click Download the screen
blinks but nothing happens. I'll hunt for it in other places.

I know. But Paul found a link that does work. It didn't
shed much light on my issue.
