In this article, we will delve into the world of thermal paste conductivity, exploring the properties of Noctua’s thermal paste and its implications for your computer’s cooling system.
Understanding Thermal Paste Conductivity
Thermal paste, also known as thermal interface material (TIM), plays a crucial role in facilitating heat transfer between a CPU or GPU and a heat sink. The primary function of thermal paste is to fill microscopic gaps and imperfections on the surface of these components, ensuring optimal thermal contact. However, not all thermal pastes are created equal, and their conductivity can significantly impact the overall cooling performance.
Types of Thermal Paste Conductivity
There are two primary types of thermal paste conductivity: electrical and thermal. While both are important, they serve distinct purposes and should not be confused.
Electrical Conductivity
Electrical conductivity refers to a material’s ability to conduct electricity. In the context of thermal paste, electrical conductivity is generally undesirable, as it can create a path for electrical current to flow between components, potentially causing damage or short circuits.
Thermal Conductivity
Thermal conductivity, on the other hand, is a measure of a material’s ability to conduct heat. In the case of thermal paste, high thermal conductivity is essential for efficient heat transfer between components. The higher the thermal conductivity, the better the thermal paste is at facilitating heat dissipation.

What is thermal paste conductivity, and why is it important?
Thermal paste conductivity refers to the ability of a thermal interface material (TIM) to transfer heat from one surface to another. In the context of computer hardware, thermal paste is applied between a CPU or GPU and a heat sink to facilitate efficient heat dissipation. The conductivity of the thermal paste plays a crucial role in determining the overall cooling performance of the system.
A thermal paste with high conductivity can effectively fill microscopic gaps and imperfections on the surface of the CPU or GPU, allowing for better heat transfer and reduced temperatures. On the other hand, a thermal paste with low conductivity may not be able to efficiently transfer heat, leading to increased temperatures and potentially reduced system performance or lifespan.
What are the common misconceptions about Noctua thermal paste conductivity?
One common misconception about Noctua thermal paste conductivity is that it is inferior to other brands or types of thermal paste. However, this is not necessarily true. Noctua’s NT-H1 thermal paste, for example, has been shown to have a high level of conductivity, comparable to or even surpassing that of other popular thermal pastes on the market.
Another misconception is that the conductivity of Noctua thermal paste degrades over time. While it is true that some thermal pastes may experience a decrease in conductivity over time due to factors such as drying out or oxidation, Noctua’s NT-H1 thermal paste has been designed to remain stable and maintain its conductivity over a long period.
How does Noctua’s NT-H1 thermal paste compare to other thermal pastes in terms of conductivity?
Noctua’s NT-H1 thermal paste has been shown to have a high level of conductivity, with a thermal conductivity rating of 8.9 W/mK. This is comparable to or even surpassing that of other popular thermal pastes on the market, such as Arctic Silver 5 or Thermal Grizzly Kryonaut. In fact, some reviews and benchmarks have shown that NT-H1 can outperform these other thermal pastes in certain scenarios.
It’s worth noting, however, that the actual performance of a thermal paste can depend on a variety of factors, including the specific application, the surface roughness of the CPU or GPU, and the pressure applied to the heat sink. Therefore, while NT-H1 may have a high level of conductivity, its actual performance may vary depending on the specific use case.
What factors can affect the conductivity of Noctua thermal paste?
Several factors can affect the conductivity of Noctua thermal paste, including the surface roughness of the CPU or GPU, the pressure applied to the heat sink, and the temperature of the system. A smoother surface can allow for better contact between the thermal paste and the CPU or GPU, resulting in improved conductivity. Similarly, applying adequate pressure to the heat sink can help to ensure good contact between the thermal paste and the heat sink.
Temperature can also play a role in the conductivity of Noctua thermal paste. At higher temperatures, the thermal paste may become less viscous and more prone to pumping out, which can reduce its conductivity. On the other hand, at lower temperatures, the thermal paste may become more viscous and less effective at transferring heat. However, Noctua’s NT-H1 thermal paste has been designed to maintain its conductivity over a wide range of temperatures.
How can I apply Noctua thermal paste to achieve optimal conductivity?
To achieve optimal conductivity with Noctua thermal paste, it’s essential to apply a small amount of paste to the center of the CPU or GPU die (the top surface of the processor). A pea-sized amount of paste is usually sufficient. Then, gently place the heat sink on top of the CPU or GPU, applying even pressure to ensure good contact between the thermal paste and the heat sink.
It’s also important to avoid applying too much pressure, which can cause the thermal paste to be pushed out of the gap between the CPU or GPU and the heat sink, reducing its conductivity. Additionally, avoid touching the thermal paste or the CPU or GPU die, as the oils from your skin can contaminate the surface and reduce the conductivity of the thermal paste.
Can I reuse Noctua thermal paste, or does it need to be reapplied?
Noctua thermal paste is designed to be a durable and long-lasting material, but it’s generally not recommended to reuse it. Once the thermal paste has been applied and the heat sink has been installed, the paste can become contaminated with dust, dirt, and other debris, which can reduce its conductivity.
If you need to remove the heat sink for any reason, it’s usually best to clean the CPU or GPU die and the heat sink surface with a lint-free cloth and a mild cleaning solution, and then reapply a new layer of thermal paste. This will help to ensure optimal conductivity and prevent any potential issues with the thermal paste.
How often should I replace Noctua thermal paste to maintain optimal conductivity?
The frequency at which you need to replace Noctua thermal paste will depend on various factors, including the operating conditions of your system, the quality of the thermal paste, and the effectiveness of the heat sink. In general, Noctua recommends replacing the thermal paste every 5-10 years, or whenever the system is upgraded or serviced.
However, if you notice a significant increase in temperatures or a decrease in system performance, it may be necessary to replace the thermal paste more frequently. Additionally, if you live in a dusty or humid environment, you may need to replace the thermal paste more often to maintain optimal conductivity and prevent any potential issues with the thermal paste.
