An airflow baffle system has an airflow baffle with a base and an airflow diverter panel. A mounting arm is connected to the base. A magnet connected to the mounting arm is operable to magnetically connect to the top of the equipment cabinet. The mounting arm is selectively pivotal in a horizontal plane relative to the base and fixable in a plurality of angular orientations. A position of the magnet is adjustable along a length of the mounting arm and the magnet is connected to the mounting arm by a flexible connection permitting the magnet to pivot about horizontal axes relative to the mounting arm. The airflow diverter panel is mountable on the base in an angled orientation and a vertical orientation. A unitary or separable riser allows adjustment of a vertical position of the airflow diverter panel with respect to the top of the equipment cabinet.
