CPU Heat Sink: How It Works, Types, Materials, and Selection Guide
A CPU heat sink is one of the most important thermal management components in a computer or electronic system. Its job is simple in principle: move heat away from the processor and release that heat into the surrounding air or another cooling medium. In practice, however, CPU cooling is much more complex. Processor power density continues to increase, while computer systems are expected to become smaller, quieter and more efficient. This means a CPU heat sink must balance several factors at the same time, including thermal conductivity, fin area, airflow, installation space, mounting pressure and cost. For PC manufacturers, server companies, industrial computer suppliers and embedded system developers, choosing the right CPU heat sink can directly affect system stability, processor performance and product reliability. This guide explains how CPU heat sinks work, the major types available, common materials and structures, and the key factors to consider when selecting or designin...
