Size: 100 x 69 x 36mm/ 3.93 x 2.71 x 1.41". In computers, heat sinks are used to cool central processing units or graphics processors. Heat sinks are used with high-power semiconductor devices such as power transistors and optoelectronics such as light emitting diodes(LEDs), where the heat dissipation ability of the component itself is insufficient to moderate its temperature.
