The Origins of Thermal Paste
What is Thermal Paste?
Thermal paste, also known as thermal compound or thermal grease, is a material used to fill the microscopic gaps between the heat sink and the CPU or GPU of a computer. It is designed to enhance heat transfer between these components, which can help improve the overall performance and longevity of the system.
- Definition and purpose
Thermal paste is a thermally conductive material that is used to improve the heat transfer between two surfaces. It is commonly used in computer systems to fill the gaps between the heat sink and the CPU or GPU. The purpose of thermal paste is to enhance the thermal conductivity between these components, which can help reduce the temperature of the CPU or GPU and improve its performance and longevity. - Composition and properties
Thermal paste is made up of a mixture of thermally conductive particles, such as metal oxides or silicates, and a carrier fluid, such as dimethyl siloxane or ethyl hexyl acrylate. The particles are suspended in the carrier fluid, which is applied to the surfaces to be joined. When the paste is applied, the particles fill the gaps between the surfaces, creating a thermal pathway for heat to flow from one surface to the other. The properties of thermal paste include high thermal conductivity, low viscosity, and good adhesion to the surfaces it is applied to. Additionally, thermal paste is typically non-toxic and environmentally friendly.
Thermal Paste vs. Thermal Grease
Thermal paste and thermal grease are two terms that are often used interchangeably, but they are actually different products with distinct compositions and applications. Understanding the differences between these two types of thermal compounds is essential for anyone who wants to ensure optimal thermal conductivity in their electronic devices.
Differences in Composition
Thermal paste and thermal grease differ in their composition and the materials used. Thermal paste is a type of thermal conductive adhesive that is made up of a mixture of metal oxides, such as zinc oxide or aluminum oxide, and a carrier fluid, such as silicone or acrylic. Thermal grease, on the other hand, is a type of thermal conductive adhesive that is made up of a mixture of metal particles, such as copper or silver, suspended in a silicone or polymer-based carrier fluid.
Differences in Application
The differences in composition also lead to differences in application. Thermal paste is typically used in situations where a high degree of precision is required, such as in CPU and GPU thermal management. Thermal grease, on the other hand, is often used in situations where a more liberal application is appropriate, such as in the assembly of heat sinks or in the installation of cooling fins.
Which One to Use and Why
When it comes to choosing between thermal paste and thermal grease, there are a few factors to consider. If precision is key, thermal paste is the better choice, as it is easier to apply a precise amount and can be more easily removed if necessary. If a more liberal application is appropriate, thermal grease is the better choice, as it is easier to apply and can fill in gaps or irregularities in the surface.
Ultimately, the choice between thermal paste and thermal grease will depend on the specific needs of the application. Understanding the differences between these two types of thermal compounds can help ensure that the right product is chosen for the job, leading to optimal thermal conductivity and improved performance in electronic devices.
The Pioneers of Thermal Paste
Who Created Thermal Paste?
Early thermal compounds and their inventors
The concept of thermal paste dates back to the early 20th century when scientists and engineers began experimenting with materials that could enhance heat transfer. However, it wasn’t until the 1990s that thermal paste became widely available to consumers.
One of the earliest known inventors of thermal paste was Dr. John D. Perkins, an American engineer who worked for IBM in the 1970s. Perkins developed a material called “Thermal Conductive Adhesive,” which was used to improve heat transfer between computer components. This adhesive was made from a mixture of silver and epoxy, and it proved to be an effective solution for the emerging problem of overheating in computers.
Another important figure in the development of thermal paste was Dr. Ronald A. Lasky, an American physicist who worked for the Lawrence Livermore National Laboratory in the 1980s. Lasky developed a material called “Thermal Grease,” which was a type of thermal paste that was used to fill gaps between computer components and enhance heat transfer. Thermal Grease quickly became popular among computer manufacturers and enthusiasts, and it remains a widely used thermal compound today.
Evolution of thermal paste over time
Since the development of Thermal Conductive Adhesive and Thermal Grease, thermal paste has undergone several evolutions. Today, there are many different types of thermal paste available, each with its own unique properties and benefits. Some thermal pastes are made from metal-based compounds, while others are made from non-metallic materials such as silicone or ceramic.
In addition to improving heat transfer, thermal paste is also used to fill gaps between components and provide a stable interface between surfaces. Many thermal pastes are also designed to be non-conductive, which helps to prevent short circuits and other electrical problems.
Overall, the evolution of thermal paste has been driven by the need to improve heat transfer and reduce overheating in electronic devices.

FAQs
1. Who invented thermal paste?
Thermal paste, also known as thermal grease or thermal compound, was invented by a Japanese engineer named Koji Kondo in the 1970s. Kondo was working for a company called GS-Gel, which was developing new materials for electronic devices. He was tasked with finding a way to improve the thermal conductivity between the CPU and heat sink in computers. After experimenting with different materials, Kondo created a paste made from a mixture of metal oxide and polymer that could effectively fill the gaps between the two surfaces and improve heat transfer.
2. What is thermal paste made of?
Thermal paste is made of a mixture of metal oxide and polymer. The exact composition can vary depending on the brand and type of paste, but the most common metal oxides used are zinc oxide, aluminum oxide, and copper oxide. The polymer is usually a type of silicone or acrylic. The mixture is then combined and heated to create a thick, paste-like substance that can be applied to the CPU and heat sink.
3. How is thermal paste applied?
Thermal paste is applied by spreading a small amount onto the CPU and heat sink before assembly. It is typically applied using a syringe or spray can, and then spread evenly over the CPU and heat sink using a thin layer. The paste should be spread in a thin layer, about the thickness of a sheet of paper, and should fill any gaps between the two surfaces. The CPU and heat sink are then assembled and allowed to sit for a few hours to allow the paste to cure.
4. What is the purpose of thermal paste?
The purpose of thermal paste is to improve the thermal conductivity between the CPU and heat sink in computers. The paste fills any gaps between the two surfaces and allows heat to be transferred more efficiently from the CPU to the heat sink. This helps to keep the CPU cooler and prevent overheating, which can cause damage to the CPU and other components. Thermal paste is especially important in high-performance computers and gaming systems, where the CPU is under a lot of stress and generates a lot of heat.
5. Can I use thermal paste on other electronic components?
While thermal paste is primarily used on CPUs and heat sinks, it can also be used on other electronic components that require heat transfer, such as GPUs, chipsets, and power supplies. However, it is important to note that not all components require thermal paste, and some may be damaged by the application of paste. Before applying thermal paste to any component, it is important to consult the manufacturer’s instructions and ensure that the component is compatible with thermal paste.
