I prefer 1 GHz base (at idle, to save energy and allow efficient cool-down between tasks), and then quickly ramp up to >4 GHz when all cores are engaged and >5 GHz for a single thread load.
Automatically controlled individual speeds on the cores would also be nice.

Does rapid and drastic temperature fluctuations have adverse effects on CPU longevity?

Yes! Thermal fatigue (as it's called) is a known factor. It rarely comes into play though, since the CPU is obsolete well before you reach its technical end of life anyway.

To avoid thermal fatigue it's better to use water cooling than regular heatpipes, since the former will make changes in CPU temperature go slower.
