I planned on doing a similar thing until I found that for some reason,
cool & quiet does not seem to work unless in 64 bit mode under linux at
least. I decided to go 64 bit because the server was going to be running
in my garage and I wanted it as cool as possible.
Has anyone managed to get CPU Throttling/CNQ working on a 32bit linux ?
