Well, temperature as read by coretemp is around 60°C for the CPU, which
appears to be quite high for a completely idle device. There seems to be
some second sensor that I'm unable to read out which controls the fan,
however.

powertop seems nice -- but I have no clue on how to read it actually. Or
how to get to know what power which process actually draws. I can just
see that by far the application with the highest "Usage" is the X server
(around 10 times that of the second largest, which usually is

  7,1 ms/s      50,2        Process        /usr/bin/X :0 -auth
/var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none
453,5 µs/s      19,9        Interrupt      [6] tasklet(softirq)

But since I have no clue on how to read those values, they mean next to
nothing to me. On the "Idle Stats" page, the CPU is 99.8% of the time in
C7 mode.

The "frequency stats" show the CPU is clocked at 800Mhz (the lowest
setting).

The "Device Stats" also mean little to me: It looks like a part of lspci
(with always 100% usage), i.e.

And a few others with 0%. The "Tunables" I don't get at all. Some are
"Bad", some are "Good" -- but I can somehow switch how they are rated?
I'm confused.
