What is the function of heat sinks in computers?

The function of heat sinks in computers is primarily to dissipate heat generated by components. As electronic devices operate, they produce heat due to electrical resistance and energy conversion. Key components such as the CPU and GPU generate significant amounts of heat, which can impact performance and longevity if not properly managed.

Heat sinks, typically made from materials with high thermal conductivity (like aluminum or copper), are designed to absorb this heat and then disperse it into the surrounding air or to a cooling system. By effectively dissipating heat, heat sinks help maintain optimal operating temperatures, preventing overheating and ensuring that the components function efficiently. This thermal management is essential for reliability and performance in computing systems.

The other options do not relate to the function of heat sinks. Increasing battery life, boosting internet connectivity, and improving sound quality are tasks handled by different components and systems within a computer, rather than by heat sinks.
