Claim 0:
1. A method for managing a heatsink of an information handling system, the method comprising:
determining, by a controller unit of the information handling system, that a vibration event is to occur, the vibration event associated with a vibration unit of the information handling system, the controller unit communicably coupled to the vibration unit, the vibration unit removably coupled to the heatsink;
causing, by the controller unit, the vibration unit to generate the vibration event, the vibration event causing the vibration unit to apply one or more vibrations to the heatsink, the one or more vibrations causing a boundary layer of particles to be removed from a surface of the heatsink;
receiving, by the controller unit, an audio stream captured by an audio sensor of the information handling system, the audio stream including a fan noise generated by a fan of the information handling system;
extracting, by the controller unit, a noise waveform from the audio stream, the noise waveform associated with the fan noise;
generating, by the controller unit, a noise-cancelling waveform based on the noise waveform, the noise-cancelling waveform having an inverted phase in relation to the noise waveform; and
causing, by the controller unit, the vibration unit to generate a noise-cancellation event, the noise-cancellation event causing the vibration unit to apply one or more noise-cancelling vibrations to the heatsink based on the noise-cancelling waveform, the one or more noise-cancelling vibrations causing the fan noise to be reduced.
