1. A data processing system to provide computer implemented services, the data processing system comprising:
hardware resources for providing the computer implemented services;
a heating unit adapted to selectively heat an interior of an enclosure in which the hardware resources are positioned;
fans adapted to selectively generate airflow from an ambient environment through the enclosure;
a fan controller adapted to manage operation of the fans and operation of the heating unit based on instructions from a temperature sensitive management controller or a temperature insensitive thermal manager;
the temperature sensitive management controller, the temperature sensitive management controller being adapted to provide the instructions to the fan controller while the temperature sensitive management controller is operating; and
the temperature insensitive thermal manager, the temperature insensitive thermal manage being adapted to direct, by providing the instructions to the fan controller, the operation of the heating unit and the operation of the fans while an internal ambient temperature of the data processing system is outside of operation limitations of the temperature sensitive management controller,
wherein the temperature sensitive management controller is separate from the temperature insensitive thermal manager, and the fan controller is separate from both the temperature sensitive management controller and the temperature insensitive thermal manager.
