Cpufreq management is not obvious and not easy for a beginner.

However it is useful to save power and reduce the noise (lower speed of fans).
It is useful on laptops and also on desktops.
I use intel procs:
4CPU : i5-2500K CPU @ 3.30GHz (mageia 1)
2CPU :  E7300 @ 2.66GHz (mageia 1 and cauldron)
On both machines, the lower frequency is 1.60GHz and I have set the governor 
to ondemand.

In MCC-> services, cpufreq was enabled, but in fact was not working.

MCC has no tool to configure cpufreq 

The plasmoid "Afficheur de charge système" (what is name?) shows the cpu 
frequency when the cursor is above it. 
IMO, ksysguard should also do that.

A question:  Why is there cpufreq and cpufreqd?
