摘要： Acoustics management at an information handling system provides reduced acoustic noise with limited performance impact by dynamically changing power dissipation as a function of cooling fan speed and ambient temperature so that preemptive power restrictions prevent excessive thermal conditions that lead to excessive cooling fan speeds and associated acoustics. A maximum cooling fan speed of less than an available maximum is set and maintained by reducing power dissipation unless power dissipation reaches a minimum, after which the minimum power dissipation is maintained and cooling fan speed is allowed to increase.

摘要： An information handling system includes a power supply coupled to a processor that includes a plurality of cores. A power system controller is coupled to the power supply and the processor. The power system controller may set each of the plurality of cores to a performance state that is below a highest performance state. The power system controller may then determine whether the power supplied from the power supply to the processor during operation is sufficient to operate each of the plurality of cores at the highest performance state. In response to the power being insufficient to operate each of the plurality of cores at the highest performance state, the power system controller may control the plurality of cores such that a subset operate at the highest performance state and the remainder operate at a performance state that is lower than the highest performance state.

摘要： An information handling system includes a processor, an air moving system, a power system, and power demand reduction circuit. The air moving system is operable to cool the processor. The power system is operable to power the processor and the air moving system. The power demand reduction circuit is operable to detect a total power system power demand that will exceed a power system output capacity of the power system in response to a processor power demand from the processor and, in response, reduce an air moving system power provided to the air moving system such that the processor power demand will no longer cause the total power system power demand to exceed the power system output capacity. The air moving system power may be increased when a decrease in the processor power demand results in the two contributing to a total power system power that will not exceed the power system output capacity.

摘要： An IHS includes an IHS chassis. A processor is located in the IHS chassis. At least one fan is located in the IHS chassis and in fluid communication with the processor. A temperature sensor is located in the IHS chassis. A fan controller is coupled to the processor, the at least one fan, the temperature sensor, and a storage device that includes a plurality of processor target temperatures that are each associated with a different ambient temperature. The fan controller is operable to receive a first ambient temperature from the temperature sensor, determine a first processor target temperature that is associated with the first ambient temperature, receive a temperature of the processor, and operate the at least one fan in order to reduce the temperature of the processor to the first processor target temperature.

摘要： Power resource allocation at a chassis that supports plural server information handling systems is enhanced with modifications to power consumption by plural cooling fans based upon available power resources. As available power decreases, at least some of the cooling fans operate at reduced speeds for a given thermal condition to consume less power. In one embodiment, a maximum allowed cooling fan speed is set with a delta value over the fan speed of one or more other cooling fans, such as a delta over the lowest commanded cooling fan speed of the chassis.
