Joao,
what I noticed was that without throttling my notebook cpu reached a
temperature-limit and switched the fan on after booting.
With throttling it takes much more time 'til the fan can be heard. Yeah,
after a while the temperature of my CPU is the same with throttling and
without throttling, but with throttling the fan makes not that noise.
