thanks, I may try that in the morning... right now, I'm using a Mel's scripts
somewhat modified to log as follows:

Oct 11 10:47:01 ayiin tempd[2359]: CPU temp: 62.0C Freq: 300 Fan 2755 rpm
Oct 11 10:47:31 ayiin tempd[2378]: CPU temp: 61.0C Freq: 700 Fan 2757 rpm
Oct 11 10:48:01 ayiin tempd[2404]: CPU temp: 60.0C Freq: 700 Fan 2758 rpm
Oct 11 10:48:31 ayiin tempd[2423]: CPU temp: 61.0C Freq: 932 Fan 2761 rpm
Oct 11 10:49:01 ayiin tempd[2429]: CPU temp: 63.0C Freq: 1400 Fan 2759 rpm
Oct 11 10:49:31 ayiin tempd[2434]: CPU temp: 62.0C Freq: 500 Fan 2757 rpm
Oct 11 10:50:01 ayiin tempd[2455]: CPU temp: 61.0C Freq: 600 Fan 2763 rpm

I may plot this for fun... i should actually log load as well...hmm
