An electronic device includes an outer case defining an internal volume, a circuit board positioned within the internal volume and having a first surface and a second surface, one or more active components mounted on the first surface of the circuit board, and a thermal management system to provide cooling for the active components. The thermal management system includes a first heat spreader in thermal contact with an active component, a second heat spreader in thermal contact with the second surface of the circuit board, thermal carriers coupled to the first and second heat spreaders to remove thermal energy therefrom, and a heat exchanger coupled to the thermal carriers to receive thermal energy therefrom and dissipate the thermal energy, wherein one thermal carrier is routed between the first heat spreader and the heat exchanger and the other thermal carrier is routed between the second heat spreader and the heat exchanger.
