Abstract: Examples for controlling an operating speed of a cooling device based on an operating mode of a processing unit, are described. In an example, a current value of a monitored current signal is determined. Based on the comparison of the current value with a predefined threshold value, a switch in an operating mode of the processing unit is determined. Thereafter, the computing device may be caused to increase the operating speed of the cooling device to a designated speed.

Abstract: In some examples, an electronic device includes an audio output device, an airflow generator to generate an airflow, and a system controller to control an operational speed of the airflow generator. The electronic device further includes an audio controller to generate a noise cancellation audio output based on an indicator of the operational speed of the airflow generator provided from the system controller to the audio controller, and send the noise cancellation audio output to the audio output device to mitigate noise produced by the airflow generator.

Abstract: Examples described herein relate to a non-transitory machine-readable medium consistent with the disclosure. For instance, the non-transitory machine-readable medium may store instruction executable by a processing resource to transfer additional power through a power delivery cable, input the additional power to a component of a computing device, and sequence the additional power with a main power supply of the computing device.

Abstract: In example implementations, a computing device is provided. The computing device includes a system management bus, a controller communicatively coupled to the system management bus, a noise generating component communicatively coupled to the controller, a noise cancellation codec communicatively coupled to the system management bus, and a speaker communicatively coupled to the noise cancellation codec. The operating parameters of the noise generating component are provided to the controller. The noise cancellation codec is to receive the operating parameters of the noise generating component from the controller via the system management bus and to generate a noise cancellation signal based on the operating parameters. The speaker outputs the noise cancellation signal to cancel noise generated by the noise generating component.
