Description: A heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device, thereby allowing regulation of the device's temperature at optimal levels. In computers, heat sinks are used to cool central processing units or graphics processors. Heat sinks are used with high power semiconductor devices, where the heat dissipation ability of the component itself is insufficient to moderate its temperature. Features: Made of high quantity aluminum, good thermal conductivity. There is glue on the back of heat sinks that can be easily stick to hardware. Designed to maximize its surface area in contact with the cool air. Light weight and used in applications where weight is a big concern. Widely use for computer, power IC, power electric device, LED light devices, etc. Specifications: Material: Aluminum Size: 14*14*6mm / 0.55*0.55*0.23" Fins: 7 Quantity: 12 Weight: 22g(approx.) Package Includes: 12 x Heat Sinks
