Abstract
A data processing unit including a first active cooling device configured to respond to a first control signal and a second active cooling device configured to respond to a second control signal. The control signals may be any type of control signal suitable to control the operation of the first and second active cooling devices. The data processing unit also includes a first control function selectively capable of providing the first control signal and/or the second control signal, and a second control function selectively capable of providing the first control signal and/or the second control signal. Logic associated with the first and second control functions is included to determine which of the control functions will provide which control signal at a specific time. Logic and/or switching or isolation apparatus is also included to prevent both the first and second control functions from attempting to provide one of the control signals simultaneously.
