摘要： Dynamically modifiable air movers can be modified during operation of a computing system to allow the performance of the fan (air flow, air flow split between exhausts) to be adjusted based on a workload being performed by the system. The physical modifications that an air mover can undergo are physical in nature and include adjusting the placement of one or more cutwaters, expanding or contracting an expandable portion of the fan housing, covering or uncovering an exhaust to provide or remove cooling to memory components, and moving a slidable strip to extend or withdraw from an exhaust. Causing one or more of these physical modifications to be made can be performed in response to the system determining that a temperature, rate of temperature change, power consumption level, rate of power consumption level change of the system or system components exceeds or has dropped below a threshold level.

摘要： Particular embodiments described herein provide for an electronic device that includes a fan. The fan can include a center shaft, fan blades that extend from the center shaft, and a plurality of magnets on an outside portion of at least two of the fan blades, where stator coils interact with the magnets to drive the blades around the center shaft. The center shaft and fan blades are a single component from the same material. In some examples, the center shaft and fan blades were created using a metal injection molding process.
