Your CPU doesn't have SpeedStep technology
EDIT: Ok, i'd already got the theese files. But voodoo monitor don't show any information. I am not the best person to handle DSDT, so i think speedstep is not enable this nx7300.
I believe 45ºC at idle and 70ºC under heavy load are normal temps.
Temperature Monitor shows tems about 45--70 degrees celsius at moment.
