2026 10 Leading CPU Heat Sink Suppliers in China

Introduction to CPU Heat Sink

A CPU heat sink is a crucial component in the computer system. Its primary function is to dissipate heat generated by the central processing unit (CPU). As CPUs operate, they produce a significant amount of heat, and if this heat is not effectively removed, it can lead to overheating. Overheating can cause the CPU to throttle its performance to avoid damage, resulting in a slowdown of the computer’s operations, and in severe cases, it can even cause permanent damage to the CPU. CPU Heat Sink

CPU heat sinks work based on the principle of heat transfer. They are usually made of highly thermally conductive materials such as aluminum or copper. The heat sink is in direct contact with the CPU, absorbing the heat from the CPU through conduction. Then, the heat is transferred to the fins of the heat sink, which increase the surface area for better heat dissipation. Depending on the design and requirements, some heat sinks are combined with fans or liquid – cooling systems to further enhance the cooling efficiency.
