Lubuntu 12.04 - fan and cpu speed control is in some way wrong

 

One very annoying point in Lubuntu 12.04 is, there is something wrong
with the control of the fan. For what i see, the CPU is always running
on maximum speed (1333 MHZ) never going down - even when i'm not doing
anything. And, i think, consequently the fan after a while begins to
work without any interruption

I've in parallel a setup with Debian "sid" powerpc and LXDE: there the
cpu speed is varying between 816 and 1333 MHZ and the fan is only
running once in a while.

Now, unfortunately i forgot, where and how i could setup/allow the cpu
speed change and where is the config file for the fan (therm_adt74x i
think).

If someone could help me out (but generally i'd say the default
settings should include that already).

PS. Oh, i've installed pbbuttonsd & powerprefs, but there i don't see
the requested options (?)
