Firstly, thank you very much for your reply.

I get the feeling however, that I may be missing a BMC because
attempting to modprobe impi_si fails with unknown device, although
dmidecode does at least suggest that it knows there are a couple of fans
in the system.. TBH, at this point I really don't know what the
motherboard is or isn't capable of.

Perhaps you might be able to tell me.. for all I know, the motherboard
simply doesn't have any sensors and has no way to access the CPU's own.
I just can't imagine Dell would sell a server chassis & motherboard
combination without the ability to check basic sensor info.

I attach outputs from dmidecode & lshw which might help.
Kind Regards,
