thermal management systems having signal transfer routing for use with electronic devices are disclosed. An electronic device includes a housing to house a first electronic component and a second electronic component. A circuit board is positioned inside the housing. The circuit board including a first signal path to communicatively couple a processor carried by the circuit board and the first electronic component. A thermally conductive structure is positioned adjacent the circuit board. The thermally conductive structure is to dissipate heat generated by the processor. The thermally conductive structure is to carry at least a portion of a second signal path to communicatively couple the processor and the second electronic component.
