Systems and methods for cooling computing device expansion modules based on airflow rates are disclosed. According to an aspect, a method includes determining airflow rates in areas available for operable connection of expansion modules within a computing device during operation of the computing device. The method also includes determining expected power consumption of the expansion modules. Further, the method includes presenting placement of the expansion modules in the areas based on the determined airflow rates and the expected power consumption of the expansion modules.

Systems and methods for cooling computing device expansion modules based on airflow rates

An apparatus includes a voltage regulator including a high-side field-effect transistor, a low-side field-effect transistor, an inductor, and a conductive net connecting the high-side field-effect transistor, the low-side field-effect transistor and the inductor. The apparatus further includes an attenuation circuit coupled to the conductive net, wherein the attenuation circuit includes an electronic switch that enables and disables an amount of attenuation provided by the attenuation circuit. Examples of the attenuation circuit include a snubber circuit and a boost resistor circuit.

Voltage regulator having a switchable attenuation circuit

An apparatus for voltage regulation device adjustment includes an external factor module that determines external factors, where the external factors include conditions external to an electronic device that affect operating performance and operating costs. The electronic device includes a voltage regulator device ('VRD') providing power to one or more components of the electronic device. The apparatus includes a firmware selection module that selects new firmware for the VRD of the electronic device in response to the determined external factors, and a firmware update module that replaces previously installed firmware on the VRD with the new firmware. The new firmware includes control settings for the VRD.

Adjustment of voltage regulator firmware settings based upon external factors

A computer-implemented method for adjusting voltage settings, according to one embodiment, includes: determining a number of components electrically coupled to an output of a voltage regulator; determining voltage tolerance information corresponding to each of the number of components; determining a voltage tolerance limit of the voltage regulator; using the determined voltage tolerance information in combination with the voltage tolerance limit of the voltage regulator to determine whether an output voltage of the voltage regulator can be reduced; calculating an amount by which to reduce an output voltage of the voltage regulator in response to determining that the output voltage of the voltage regulator can be reduced; and sending one or more instructions to the voltage regulator to reduce the output voltage of the voltage regulator by the calculated amount.
