thermal isn't working on this board (if you mean /proc/acpi/thermal_zone ...)
I also tried a vanilla kernel & it showed the same higher temperature ;(
here the last mail (on lkml it was corrupted) - I don't know if youwere able to read it

ok, tested the vanilla-kernel this morning and it shows the exact hightemperatures (with CONFIG_THERMAL=y)
I've got a question:
when trying to disable thermal it just sits there & won't change:<*> Hardware Monitoring support  ---> -*- Generic Thermal sysfs driver  --->
it seemingly depends on other things:Selected by: ACPI_THERMAL && !X86_VOYAGER && ACPI && ACPI_PROCESSOR
is it safe to disable acpi_processor and acpi or CONFIG_THERMAL ingeneral ? or will it burn down my box ? ;)
I'm asking this because it says/writes:CONFIG_ACPI_THERMAL:                                                    │ │                                                                         │ │ This driver adds support for ACPI thermal zones.  Most mobile and       │ │ some desktop systems support ACPI thermal zones.  It is HIGHLY          │ │ recommended that this option be enabled, as your processor(s)           │ │ may be damaged without it.
