Electronic system having heat dissipation and feed-forward active noise control function and related method

A method of providing heat dissipation and feed-forward active noise control function in an electronic system, comprising:

• operating a fan module in the electronic system according to a fan control signal for providing heat dissipation;
• providing the fan control signal using an embedded controller in the electronic system;
• detecting a wide-band noise generated during an operation of the fan module and providing a corresponding wide-band noise signal using a reference microphone in the electronic system;
• generating a noise-cancellation signal according to the speaker control signal using a micro speaker module in the electronic system;
• providing a virtual error signal according to a first transfer function, a second transfer function and the wide-band noise signal using an active noise cancellation (ANC) controller in the electronic system;
• and
• providing the speaker control signal according to a synchronization signal, the wide-band noise signal and the virtual error signal using the ANC controller, wherein:
• the synchronization signal includes information associated with a structure and an operational setting of the fan module;
• the first transfer function is a transfer function between the reference microphone and a physical microphone when the micro speaker is not in operation;
• the second transfer function is a transfer function between the micro speaker module and the physical microphone when the fan module is not in operation;
• and
• the noise-cancellation signal includes a plurality of noise-compensation signals for canceling noises generated during the operation of the electronic system.
