I'm going to state the obvious: why not just underclock the CPU?

Also, users of lvcool should be warned that cycling the CPU
temperature over a larger range may cause faster CPU degredation
than simply running it at a higher base temperature.  I assume
less "cpu degredation" is the preceived benefit of running at a
lower temperature, since nobody has mentioned measuring overall
system power consumption.  (And comparing the added cost of
electricity to the cost of replacing parts that break because
they've been power cycled too often.)
