ABSTRACT:
A heat sink has a plurality of pipes that are connected to an array of magnets. The plurality of pipes are connected to a lid that is operatively connected to an integrated circuit. Temperature sensors are disposed on the lid to measure temperatures of hot spots of the integrated circuit. Dependent on a temperature of one of the hot spots, the array of magnets may be used to propagate thermally conductive fluid toward the hot spot through the lid using the plurality of pipes.
