Particular embodiments described herein provide for an electronic device that can be configured to receive data related to thermal properties of a first heat source, activate an air mover based on the received data related to the thermal properties of the first heat source, where a majority of the air moved by the air mover is biased in a first direction, determine that the majority of the air should have a bias in a second direction, and reverse a direction of rotation of the air mover to cause the air moved by the air mover to have a bias in the second direction. In an example, the first direction towards the first heat source and the second direction is opposite the first direction and towards a second heat source.
