   Thanks No0p and every one else that made suggestions,  I took the fan 
and heat sink off.  I had vacuumed it.  I blew it out all out and 
started to put it together and found what looked like a sewing thread 
where the heat sink makes contact with the processor. I cleaned the 
contact surface good and replaced the the thermal grease that i had left 
back when I replaced the fan this past summer.   I started her up 
exporting a file and watched the temperture rise with the sensor program 
from 42deg. to 58 and stopped right there. Beautiful.
                                    Thanks all.     Problem solved.
