Dunno if this helps.
My cpu is an Intel I7-2670QM.
The related files, you might need to check are:
/etc/laptop-mode/conf.d/cpufreq.conf
As far as I remember I chaned nothing here in the past.
Second one is:
/etc/modules
in here I set the following entries:
powernow-k8
cpufreq_powersave
cpufreq_ondemand
cpufreq_userspace
Third one, which might be related:
/etc/modules-load.d/modules.conf
In here are alsoi the three entries as above:
powernow-k8
cpufreq_powersave
cpufreq_ondemand
cpufreq_userspace
I think, the powernow-k8 entry is no more needed, and is a relic from old times.
Additionally check
/etc/laptop-mode/laptop-mode.conf
Although you might run a desktop computer, the package laptop-mode might be helpfull.
Hope this helps.
