    Abstract: A device for processing graphics data may include a plurality of graphics processing units. The device may include a fan to dissipate thermal energy generated during the operation of the plurality of graphics processing units. Each of the plurality of graphics processing units may generate a pulse width modulated signal to control the speed of the fan. The device may include one or more monitoring units configured to monitor a signal controlling the speed of the fan. One or more of the plurality of pulse width modulated signals may be adjusted based on the monitored signal. One or more of the plurality of pulse width modulated signals may be adjusted such that a signal controlling the fan maintains a desired duty cycle.

    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.

    Abstract: A printed circuit board (PCB) includes an exterior section having a first set of layers including an outermost conductive layer. The PB further includes an interior section, adjacent to the exterior section, having a second set of layers including a first conductive layer corresponding to a first end of the interior section, a second conductive layer corresponding to a second end of the interior section opposite the first end, and a third conductive layer disposed between the first conductive layer and the second conductive layer. The exterior section further includes a set of vias extending from an outermost conductive layer to the first conductive layer. The interior section further includes a buried skip via extending from the first conductive layer to the third conductive layer.
