Intel mobile CPUs allow the core voltage to be reduced to reduce power consumption and heat by slowing down the processing speed. IBM/Lenovo ThinkPads come with a utility that lets you create customized power profiles that adjust the trade-offs between processing speed, battery life, heat and fan noise. Does Mac OS-X 10.4 provide Intel Mac users with similar capabilities?
