The chipset rarely matters (I've yet to encounter any PC chipset that
natively handles full fan, voltage, and temperature monitoring), but
the motherboard model can tell me a lot.  :-)

Boards have to include an external H/W monitoring IC (such as one from
National Semiconductor (LMxx), AMD, or Winbond), have thermistors placed
around the board, and have the H/W IC tied into the ISA or SMBus.
Sometimes the H/W monitoring IC also acts as a super I/O chip (which
means it handles serial, parallel, keyboard, mouse, and floppy disks --
and sometimes IDE).

I can't find anything on Intel's site that clues me in; all the PDFs
are vague as far as what chips are on the board.

I tried searching for a high-resolution photo of the L440GX on Google
Images, but I find none which are sharp/clear enough.  The best I
could find was this:

I see Intel northbridge and southbridges, a Cirrus Logic (VGA?) chip, an
Intel flash chip (probably for CMOS), and an Intel NIC.  Four chips I
don't recognise are an Intel chip on the far right, a mystery chip
at the bottom of the board (can't make out company logo), and two
chips with "E" in their company logo (right of PCI slots).  Possibly
one of these handles H/W monitoring.

If you can reboot the system and go into the BIOS, see if you can
find anything that looks remotely like CPU and system temperatures,
as well as voltages.  If there's no such menu, the board likely has
no support for such.

P.S. -- You're the 2nd person I've encountered in under a week who's
using 440BX/GX-based hardware in present day.  I would not be
surprised if the board is simply going bad/failing due to age.  :-)
