Subject: Useless thermal acpi driver ?

Hi all...

I have a couple boxes where the thermal acpi driver gives this:

bran:~> sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +26.8°C  (crit = +100.0°C)

bran:~> acpi -t
No support for device type: battery
     Thermal 1: ok, 27.0 degrees C

It stays _always_ the same, there is no difference if I run some number
crunchin, or even if one of them is overclocked from 2.8 to 3.0 GHz.
They are 1U supermicro boxes, ventilation is good, but I don't trust this
measures...
It looks like the system is using some kind of 'generic' acpi TZ driver,
but as I'm used to good-ol' sensors modules, I don't know where to look.

Previously I used the w83627hf module from sensors.
This is the system info:
