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 fins have an interleaved position with higher impedance and a separated position with a lower impedance that can increase cooling airflow. In one example embodiment, a central processing unit couples to a first circuit board and the first set of cooling fins and a graphics processor couples to a second circuit board and the second set of cooling fins so that movement of the circuit boards moves the cooling fins between the interleaved and separated positions.
