Ahh, sorry, I misread the email. I meant when I put the c1d to 2.1GHz I get around 30W. regarding ati, I observe exactly the same thing ~1-2W savings with powersave. > I don't do anything to the fans and unless the CPU gets > busy (ondemand governor) the temperature doesn't > seem to be excessive. I am also using the ondemand governor, but in addition force the minimum fan speed a little higher (it is already 24 C in Berlin nowadays...)
