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.
