Abstract: Low-profile fasteners with springs that are either integrated with the fastener or are a physically separate component can provide a more evenly distributed load to a heat transfer device, such as a vapor chamber or a heat pipe. The low-profile fasteners do not increase the height of the base of a mobile computing device as the spring and the portion of the fastener that extends past the spring fit within a recess or cavity of the heat transfer device. The spring can be a diaphragm spring, a wave spring, or another suitable spring. The use of low-profile fasteners with springs to fasten a heat transfer device to a mainboard may allow for designs with a smaller mainboard area, which can leave room for a larger thermal management solution (which can increase cooling capacity) and allow for a greater thermal design power for the system.

Abstract: Example field replaceable fan assemblies for peripheral processing units and related systems and methods are disclosed. An example apparatus includes a temperature sensor; a fan having a base; at least one memory; machine readable instructions; and processor circuitry to execute operations corresponding to the machine readable instructions to determine a first temperature based on an output of the temperature sensor; and cause the base of the fan to move based on the first temperature.

Abstract: An apparatus is described. The apparatus includes a semiconductor chip package having a semiconductor chip therein. The semiconductor chip package to communicate a temperature of the semiconductor chip. The apparatus includes a heat sink that is thermally coupled to the semiconductor chip package. The heat sink has fins. The apparatus includes a fan. The apparatus includes a temperature sensing device. The temperature sensing device is to sense a temperature of an ambient before the ambient is warmed by the fins. A rotational speed of the fan is to be determined from the temperature of the semiconductor chip and the temperature of the ambient.

Abstract: A circuit board and vapor chamber are disclosed. Connectors couple the vapor chamber to a circuit board. The connectors extend from the bottom of the vapor chamber. The connectors fix the vapor chamber to the circuit board such that the bottom of the vapor chamber thermally couples to a heat source on the circuit board. The circuit board has a connector assembly that couples to the vapor chamber.

Abstract: An improved rolling element bearing assembly is provided which is particularly applicable for use in gas turbine engine gearboxes. The rolling element bearing includes an inner ring mounted to a rotatable shaft and an outer ring mounted to a stationary structure. The inner and outer rings define a raceway for a plurality of rolling elements. The rolling element bearing assembly includes the bearing and a compliant anti-rotation ring compressed between the bearing outer ring and the stationary structure. The compliant ring provides improved frictional engagement and improved bearing damping between the bearing outer race and the stationary structure preventing outer ring rotation within the stationary housing.
