An apparatus includes a thermally conductive section with a side facing approximately parallel to an axis and adapted to be thermally coupled to a circuit component, and includes a fluid supply section which directs a fluid flow along the axis toward an opposite side of the thermally conductive section. The thermally conductive section splits the fluid flow into a plurality of flow portions which each flow through the thermally conductive section in a direction approximately parallel to a plane perpendicular to the axis, the flow portions exiting the thermally conductive section at a plurality of respective locations disposed along a substantial portion of the periphery of the thermally conductive section.
