A vehicular driver monitoring system includes an interior rearview mirror assembly. A PCB is accommodated by a mirror head and a heat generating electronic component is disposed at the PCB. A heat sink is thermally coupled with the PCB and, when the heat generating electronic component generates heat, the heat sink draws heat away from the PCB. A first plurality of vents are formed through a lower portion of the mirror casing and a second plurality of vents are formed through an upper portion of the mirror casing so that cooling airflow is drawn into the mirror head via the first plurality of vents formed through the lower portion and exits out of the mirror head via the second plurality of vents formed through the upper portion to draw heat away from the PCB and out of the mirror head.
