On a good day, HP will have documented their ACPI zones well enough for you to tell what they are.  It's also possible that contacting HP's support might dig up more info.

Failing that, however, you might be able to look at the Hardware/Health Status page in the BIOS, note the relative temperatures being displayed and what they are with, and then compare the sysctl output after a boot.  You might also be able to boot into Windows and try running a vendor-supplied thermal monitoring utility, and either look for debugging info, perhaps in the logs if it produces any, or again try to figure out the correspondence.
