Well, that's a bit opinable, since if I put as max cpu-freq 1.0GHz instead of 2.2GHz with less vcore, my cpu will for sure run a lot warmer...

that won't work since I've already trying starting powernowd manually in terminal but it exits with an error since under
/sys/devices/system/cpu/cpu0/cpufreq/ there's no trace of available scaling options..
