Abstract
An electronic device is provided that is able to detect noise to which the electronic device is exposed and an internal temperature of the device. The device contains a cooling unit to cool at least a portion of the electronic device and a subsystem coupled to the microphone and/or a thermal sensor and further coupled to the cooling unit. The cooling unit adjusts according to the detected noise and internal temperature. A method for cooling an electronic device is also provided. The method comprises monitoring the noise of the device's ambient environment, monitoring an internal temperature of the device, and actuating a user interface. The method provides for cooling the device by adjusting fan speed, clock speed, or power supply voltage applied to the device based on the noise of the ambient environment, an internal temperature of the device, and actuation of the user interface.
