A system is provided, which manages, by a microcontroller internal to a fan installed in a server, power data associated with the fan, wherein the fan includes two pins configured to communicate signals based on an inter-integrated circuit (I2C). During operation of the fan, the microcontroller measures a first and second amount of power consumed by the fan at a first and second time. The microcontroller transmits, via the two pins, the information to a system management entity which monitors and manages the server, wherein the system management entity controls a speed of the fan in response to receiving the measured power data and based on a net power comprising a difference between a total amount of power consumed by the server and an amount of power consumed by the fan.

Fan enhancements to improve server performance and quality

A micro control unit ('MCU') controls operation of a cooling fan in a compute device. The MCU is responsive to determining that a fan speed of the cooling fan is above a predetermined speed threshold to periodically determine power consumption of the cooling fan. In response to a periodic determination of power consumption exceeding a predetermined power consumption limit, the MCU reduces the fan speed of the cooling fan by a predetermined increment and continues periodically determine power consumption of the cooling fan. Upon determining that the power consumption does not exceed the predetermined power consumption limit, the MCU discontinues any prior reduction of the fan speed.

System and method for compute system cooling fan control

Examples herein relate to an adjustment of a power limit of a processor. Examples disclose setting the power limit of the processor. The examples also obtaining a temperature difference between a die temperature of a core within the processor and a throttle temperature. In response to a determination that the temperature difference is at most equal to a temperature activation point, adjusting the power limit of the processor so that the adjust power limit is less than the set power limit.
