Abstract
A graphics subsystem includes a printed circuit board (PCB), a set of one or more fans, and a heat sink. A graphics processing unit (GPU) is integrated into the PCB. The PCB is shortened to occupy a portion of the width of the graphics subsystem. The heat sink is coupled to the PCB and/or GPU and configured to extend beyond an edge of the PCB, thereby occupying a larger portion of the width of the graphics subsystem compared to the PCB. A first fan is disposed partially or fully beyond the edge of the PCB and is configured to direct air through the portion of the heat sink that extends beyond the edge of the PCB, along a first airflow path, and out of the graphics subsystem. A second fan is configured to direct air through the heat sink, along a second airflow path, towards the GPU.
