Abstract
It is anticipated that in the future, increasing power den-
sities and resultant temperatures will often be the dominant
limit to processor performance and a significant component
of cost. Dynamic thermal management (DTM) techniques
address this issue by allowing the thermal solution to be
designed for a temperature less than the peak. Evaluating
DTM and other processor thermal properties requires re-
liable tools for processor thermal modeling. In particular,
the processor heat-sink model plays a crucial role, but much
prior work in DTM, including our own, is based on simplis-
tic assumptions of heat-sink behavior. Using more realistic
heat sink simulation, this paper corrects our previous work
