I find that sometimes different distros have different default supported configs and grok to different degrees various features and hardware. You might try booting various live cds and see what they grok. I loved knoppix to quickly tell how linux friendly a given machine is. Maybe ubuntu or fedora will give you a different view. Live cds often have elaborate complete detection stages... boot and see what chips and config it detects. You might try older versions of distros that have better support for older hardware. Maybe try the version of the live cd that was released one year after the introduction of the laptop.

I have a very old laptop I'm trying to rehabilitate and use with Debian: it's got an AMD Turion chip and 1G of RAM. Works fine. But one annoying problem under Linux: the fan runs flat out all the time. If the fan connection to the MB is only two pins it may not have the ability to operate at anything other than full speed. Check the MB
keyword, 'may' on my notebook the main fan has two pins but it has variable speed... so i guess ymmv
so +1 for checking the manual or contact manufacturer website/support
manual. As this is a laptop you may find it hard to locate information about fan control. You could add a circuit to do variable speed control of the fan but it may be difficult, if not impossible, to fit it in to the laptop case.
again depending on notebook/laptop model... many of the older models (before space became such a fixating factor) actually has lots of crawl space, just yesterday i added some custom components to one of my old HP's and recall thinking how cool it is that it can all fit inside the case :)

As I mentioned in my initial post, the fan speed is variable, so it seems clear it's controllable. Just not - so far - by Linux. David - your suggestion is a good one. I don't actually like it (because it entails quite a bit of work), but if I'm to pursue this that's definitely the best way to go. Thanks. -- Giles https://www.gilesorr.com/ gilesorr@gmail.com

so, lm-sensors (sensors-detect) / pwmconfig & sensors and/or fancontrol (https://linux.die.net/man/8/fancontrol) does not work? then, surely checking manual (for custom requirements) or contacting manufacturer is the only way to go, or am i missing something? on my linux fancontrol is enabled by default and with default config I also found this, which explains the tech behind fan control quite well: http://www.tomshardware.com/answers/id-2559018/fan-speed-control-pin-pin-pin... as you say, fan speed on your rig is variable, so afaik it is a question of 2-pin, 3-pin & 4-pin and your modules, config and software. hth Andre
