Hello,
I did. It's consuming some 90 Watts at idle.
Actually, it's an Athlon

Is there any way to take advantage of this into OpenBSD in order to reduce the
system consumption by falling the CPU in C1 state or higher ?

Suspending has worked for some time on OpenBSD. Have a look at: zzz
But you might want to do your homework about the wakeing up part.

You can use apm. It will only save a few watts, but it may reduce the
cooling costs by reducing the heat generated by the CPU. If you have
_many_ machines you can easily reduce the temperature of the server room
by a few degrees C.

Do you mean change the frequency depending on load on the computer...?
