[Hidden-tech] Mac Book Pro Heat Question

[Jan Werner]

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?
