a first fan positioned proximal the first side;
a second fan positioned proximal the second side; and
a diverter positioned between the first and second sides, the first and second fans fluidically connected via first and second airflow pathways, the first airflow pathway passing from the first fan to outside the frame through a first aperture of the frame to the second fan through a second aperture of the frame, the second airflow pathway continuously extending within the frame from the first fan to the second fan.
