and most of the time, it will be in the range of 30-60C degrees,
This is Prescott we're dealing with.
Try 70C+ under load.
And see slide 4.
Intel:
at 90nm, ~50% of total power is "active leakage power".
at 130nm, only ~28% of total power is "active leakage power".
Active power increases moderately from 130nm to 90nm, but the leakage increase just ruins Prescott.
