Is there any chance that you could post these rules? I'm using an Athlon64 3200+, and the lowest that I can get the CPU going is 1.8GHz (at least, that's what the powernow-k8 module is reporting). I'd love to slow the thing down even further at idle.
I was experimenting with spinning down drives in my chassis too (in addition to MythTV, I have a RAID-5 running in there), but unfortunately, SATA drives don't seem to support spinning down via hdparm. -- Joe --- Mario Limonciello <[EMAIL PROTECTED]> wrote: > Jim Reith wrote: > > >> > Even though my Myth backend does not sit in the > lounge, it does sit in > >> > the study and the fan noise is driving the > family nuts to point they > >> > want the backend shutdown when they are in > there. > >> > > >> > I have done heaps of searching around and can't > seem to find any solid > >> > info but I would like to be able to throttle > back the fan on the CPU > >> > when the backend is idling as it seems to most > of the time. > >> > > >> > I have lm_sensors running and I know the speed > of the fan, but I can't > >> > find any way to control it.
