It looks like fan and thermal not present in DSDT on your system.
To make sure you should check for '_TZ' (thermal zone definition) and
'PNP0C0B' (fan device h/w ID) entries in your DSDT.
Look here for reference: http://acpi.sourceforge.net/dsdt/index.php

Thanks. Indeed, neither '_TZ' nor 'PNP0C0B' were present in the
decompiled DSDT. I upgraded my BIOS to the latest version but nothing
changed in those departments.
My question now is: what's my next step, if any? Am I strictly at the
mercy of the vendor - HP - or is there something that could be done?

Hi,
my machine is HP's XW6200 desktop, running LFS with a 2.6.15 kernel.
When loading acpi's 'fan' and 'thermal' modules, the dircetories
'/proc/acpi/{fan,thermal_zone}' appear, but contain nothing. No
complaints appear on 'dmesg', and other modules ('button' and
'processor') seem to behave well.
I wish to find out whether the problem is due to hardware limitations,
software limitations, or perhaps software configuration, and I'm not
sure how to go about it. I write here as I failed to come up with much
elsewhere online.
Some further information that could be helpful:
