Abstract
A portable information handling system rejects excess thermal energy from within a housing by blowing a cooling airflow with a cooling fan across first and second sets of cooling fins and out an exhaust. The cooling fan has an upper and lower intake and moves vertically within the housing to adjust spacing at the upper intake. The cooling fan exhaust couples to one of the sets of cooling fins to exhaust across both sets of cooling fins when interleaved and the one set of cooling fins when spacing at the upper cooling fan intake increases.
