In summary, thermal paste is an important component in maintaining the proper functioning of a computer system. It improves heat transfer, reduces thermal resistance, is easy to apply, and is low cost.

How does thermal paste work?

Thermal paste, also known as thermal grease or CPU paste, is a material used to fill the microscopic gaps between the CPU and heatsink to enhance heat transfer. The paste is typically made of a mixture of metal oxides, such as zinc oxide, and a carrier fluid, such as silicone or acrylic. The carrier fluid evaporates after application, leaving behind a thin layer of metal oxide particles that fill the gaps between the CPU and heatsink.

The main function of thermal paste is to increase the surface area for heat transfer between the CPU and heatsink. By filling the gaps between the two components, the paste allows for better contact and increased heat conduction. The metal oxide particles in the paste also have a higher thermal conductivity than the air or the heatsink itself, which further aids in heat transfer.

The effectiveness of thermal paste depends on its thickness and evenness of application. If the paste is too thick, it can prevent the CPU and heatsink from making good contact, reducing the effectiveness of heat transfer. On the other hand, if the paste is too thin, it may not fill all the gaps between the two components, reducing its ability to enhance heat transfer.

It is important to note that thermal paste is not a permanent solution and will eventually dry out over time. As a result, it is recommended to check the paste’s condition periodically and replace it as needed to maintain optimal thermal performance.
