A portable computer includes a housing containing a circuit component, and a temperature adjusting arrangement which has a thermally conductive section with a side facing approximately along an axis and thermally coupled to the component. A fluid supply section directs a fluid flow along the axis and 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.
