Detailed explanation of CPU heat dissipation principle: from heat conduction to efficient cooling
In modern computer systems, the CPU (central processing unit) is the core computing unit, and its performance directly affects the overall operating efficiency of the machine. However, with the continuous improvement of CPU performance, its power consumption and heat generation have also significantly increased. An efficient cooling system is crucial for maintaining the stable operation of the CPU.

Thermal conductivity is the ability of a material to conduct heat, measured in W/(m · K). The thermal conductivity of common radiator materials is as follows:
Copper: approximately 400 W/(m · K)
Aluminum: approximately 237 W/(m · K)
Silver: Approximately 429 W/(m · K)
Copper and aluminum have become the main materials for heat sinks due to their high thermal conductivity and low cost.
Thermal interface materials are used to fill the small gaps between the CPU and the heat sink base, improving thermal conductivity efficiency. Common ones include silicone grease, which is easy to apply. A heat pipe is an efficient heat conduction component that utilizes the phase transition (liquid to gas) of the working fluid to transfer heat. The interior of the heat pipe is in a vacuum state, filled with a small amount of working fluid (such as water or ammonia). When one end of the heat pipe is heated, the working fluid evaporates and flows towards the cold end, releasing heat and condensing back to form a cycle.

Convection heat dissipation: The transfer of heat, convection heat dissipation is the process of removing heat through the flow of fluid (usually air or liquid). The convective heat dissipation of CPU heat sinks mainly relies on fans and heat dissipation fins. Heat dissipation fins improve heat dissipation efficiency by increasing surface area. The design of fins needs to consider the following factors:
Spacing: Too dense will hinder air flow, while too sparse will reduce the heat dissipation area.Shape: Wave shaped, needle shaped and other designs can enhance turbulence and improve heat dissipation.The fan accelerates air flow through convection, taking away heat from the heat dissipation fins. The performance parameters of a fan include: air volume: the volume of air passing through the fan per unit time, measured in CFM (cubic feet per minute). Wind pressure: The static pressure generated by the fan affects the ability of air to penetrate the heat dissipation fins. Noise: usually expressed in decibels (dB), low-noise design enhances user experience. The size, speed, and noise level of the fan need to be optimized according to the cooling requirements. PWM (Pulse Width Modulation) fans can automatically adjust their speed according to temperature, achieving a balance between silence and heat dissipation.
The working principle of CPU heat sink involves multiple aspects such as heat conduction, convective heat dissipation, and radiative heat dissipation. Through scientific design and optimization, the heat sink can effectively reduce CPU temperature and ensure stable system operation. Whether it is air-cooled or liquid cooled, an efficient heat dissipation system is an indispensable component of modern computers. I hope this article can provide you with valuable reference and help you gain a deeper understanding of the working principle of CPU heat sinks.
