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 - Color: Silver. - Material: Aluminum. - Size: 1.50 x 1.50 x 0.50cm/ 0.59 x 0.59 x 0.20 inch. - The small aluminum heatsink is designed to maximize its surface area in contacts with the cool air. - Made of high quantity aluminum, the small aluminum heatsink is of good thermal conductivity. - The small aluminum heatsink is of glue on the back, so that can be easily stick to hardwares. - The small aluminum heatsink is widely used for computer, power IC, power electric device, LED light devices, etc. - The small aluminum heatsink is of light weight, and used in applications where weight is a big concern.Package list: 24 x aluminum heatsinks
