Methods, apparatus, systems, and articles of manufacture to manage heat in a CPU are disclosed. An example apparatus includes a metric collection agent to output a metric representative of a property of the central processor unit including a first core and a second physical core, the first physical core and the second physical core mapped to first and second logical cores by a map. A policy processor is to evaluate the first metric to determine whether to change the map to remap at least one of the first and second logical cores relative to the second one of the first and the second physical cores to move a process between the first and second physical cores to adjust the property, the moving of the process between the physical cores being transparent to an application/OS layer. A mapping controller is responsive to the policy processor to change the map.
