  • Patent number: 8265799
    Abstract: A first reception unit receives “ambient temperature” which is a temperature of surroundings where the computer is installed. A second reception unit receives “first device temperature” which is a temperature of a first device provided in the computer. A third reception unit receives “second device temperature” which is a temperature of a second device provided in the computer. A fan rotation speed indicating unit determines the rotation speed of the fan based on a comparison between the ambient temperature, first device temperature, and second device temperature which are received by the first to third reception units and a fan rotation speed description table describing a relationship between the respective temperature and fan rotation speed and instructs the fan to rotate at the determined rotation speed.

  • Publication number: 20120106074
    Abstract: A mechanism is provided for integrated power delivery and distribution via a heat sink. The mechanism comprises a processor layer coupled to a signaling and input/output (I/O) layer via a first set of coupling devices and a heat sink coupled to the processor layer via a second set of coupling devices. In the mechanism, the heat sink comprises a plurality of grooves on one face, where each groove provides either a path for power or a path for ground to be delivered to the processor layer. In the mechanism, the heat sink is dedicated to only delivering power and does not provide data communication signals to the elements of the mechanism and the signaling and I/O layer is dedicated to only transmitting the data communication signals to and receiving the data communications signals from the processor layer and does not provide power to the elements of the processor layer.
