well
I was thinking about, how do you see the:
temperature, of the cpu, and motherboard
and how to see the fans speed.
i mean USing my os, and since BIOS can, it shuld be possibel.
And a quick reserarch on google gave me this hint: ACPI , but is that right ??

Hi,

I'm sure someone will correct me if I'm wrong, but AFAIK, this stuff is motherboard-specific and needs to be done via a motherboard driver.

Cheers,
Adam

Hello,
Usually you can read it through Hardware Monitor,but note that this is no
compatible in all system.
In old architecture HW monitor was avaiable in the pci,today in some architecture (intel)
you can find it in Super I/O chip,but you must have Datasheet of your
Super I/O.
You can find some temperature probe also through SMBus,but you
always need datasheet of your sensor to parse data.

For the CPU temperature you can get some information from MSRs (at least for Intel CPUs). See section 13.5.5 in Vol 3A of the Intel manuals.
