  • Publication number: 20210298199
    Abstract: A graphics subsystem includes a printed circuit board (PCB), a blower, 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 similarly occupies just a portion of the width of the graphics subsystem. The blower is disposed adjacent to the PCB and heat sink and configured to occupy the full height of the graphics subsystem. The blower is further configured to intake air from both the top side of the graphics subsystem and the bottom side of the graphics subsystem. In this configuration, the blower provides an elevated air flow rate in order to facilitate cooling of the PCB and/or GPU.

  • Publication number: 20210294397
    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.

  • Patent number: 9829967
    Abstract: A power subsystem is configured to manage the maximum power usage of a computer subsystem. A power detector determines when power usage approaches the maximum capability of the power supply. The power detector generates a signal that corresponds to power usage. A controller then applies the signal to the system voltage regulator as a secondary regulation function such that the output voltage is reduced in a manner that supports maximum operating voltage while limiting power usage to within the capability of the power supply. The controller may configure the signal to implement the secondary regulation function as a modification of the feedback voltage, the reference voltage, or the current feedback of the regulator. As a result the subsystem causes the computer subsystem to operate at an optimum point on the voltage-current curve of the power supply.
