I thought that power consumption and heat dissipation in the CPU were 
more or less proportional but evidently my belief was too naif  :-)

I guess that the same thing holds for the Athlon64 so prolly centrino is 
the only CPU were I can get a substantial power saving by decreasing the 
freq when I don't need much of it (which is almost always), is this 
correct?

Thanks,
 Roberto
