Thermal Conductivity and Performance

Thermal Conductivity

Thermal conductivity is a measure of a material’s ability to transfer heat. It is expressed in watts per meter per degree Celsius (W/m·K). The higher the thermal conductivity, the better the material is at transferring heat.

For thermal paste, thermal conductivity is one of the most important factors in determining how well it will perform. A thermal paste with a high thermal conductivity will be able to transfer heat from the CPU to the heatsink more effectively, resulting in lower CPU temperatures.

There are a number of different materials that are used in thermal paste, including metal oxides, ceramics, and carbon compounds. Each material has its own unique thermal conductivity. For example, silver has a thermal conductivity of 429 W/m·K, while zinc oxide has a thermal conductivity of 130 W/m·K.

The table below shows the thermal conductivity of some of the most common materials used in thermal paste:

|Material | Thermal Conductivity (W/m·K)|
|:—|:—|
|Silver | 429|
|Zinc Oxide| 130|
|Copper | 401|
|Aluminum | 238|
|Carbon | 200-600|

Performance

The performance of a thermal paste is determined by a number of factors, including its thermal conductivity, viscosity, and workability.

Thermal conductivity is the most important factor in determining the performance of a thermal paste. A thermal paste with a high thermal conductivity will be able to transfer heat from the CPU to the heatsink more effectively, resulting in lower CPU temperatures.

Viscosity is also an important factor in determining the performance of a thermal paste. A thermal paste with a low viscosity will be easier to apply and will spread more evenly, resulting in better heat transfer.

Workability is a measure of how easy a thermal paste is to apply and remove. A thermal paste with good workability will be easy to apply and remove without leaving any residue.

Compatibility with Different CPUs and Coolers

Compatibility plays a crucial role in choosing the right thermal paste for your specific CPU and cooler setup. It’s essential to ensure that the thermal paste you select is:

Compatible with the CPU’s socket: Different CPU sockets require specific thermal paste formulations to ensure proper contact and heat transfer.
Capable of covering the CPU’s die size: The thermal paste must be able to fill the gap between the CPU die and the cooler, creating a uniform layer for optimal heat dissipation.
Suitable for the cooler’s material: Some thermal pastes may not be compatible with certain cooler materials, such as copper or aluminum. Check the thermal paste’s specifications to ensure compatibility with your cooler.
Non-conductive: Thermal pastes are designed to be non-conductive, preventing electrical shorts that could damage the CPU or other components. It’s important to use a thermal paste that is specifically labeled as non-conductive.

Specific Considerations for Different CPUs and Coolers

AMD CPUs: AMD CPUs typically require a thicker thermal paste application compared to Intel CPUs due to their larger die sizes.
Intel Core 13th and 12th Gen CPUs: These CPUs have a high thermal density and require thermal pastes with high thermal conductivity.
Liquid Coolers: Liquid coolers generally require less thermal paste than air coolers because they make better contact with the CPU die.
Stock Coolers: Stock coolers provided by CPU manufacturers often have pre-applied thermal paste that is sufficient for basic cooling needs.

CPU Socket	Recommended Thermal Paste Thickness
AM4 (AMD)	0.2-0.3mm
LGA 1700 (Intel 12th and 13th Gen)	0.1-0.15mm

Thermal Resistance and Heat Dissipation

Thermal resistance, measured in Kelvins per watt (K/W), quantifies the ability of a material or interface to impede heat flow. In the context of thermal paste, it represents the resistance to heat transfer between the CPU die and the heat sink. Lower thermal resistance translates to better heat dissipation and, consequently, lower CPU temperatures.

6. Thermal Conductivity

Thermal conductivity, expressed in watts per meter-Kelvin (W/(m·K)), measures a material’s ability to conduct heat. Thermal paste acts as a bridge between the CPU die and the heat sink, facilitating heat transfer between these components. Higher thermal conductivity values indicate better heat transfer capabilities, resulting in lower CPU temperatures.

The table below summarizes the key specifications of some commonly used thermal pastes:

Thermal Paste	Thermal Resistance (K/W)	Thermal Conductivity (W/(m·K))
Noctua NT-H2	0.015	12.5
Arctic Silver 5	0.012	8.5
Thermal Grizzly Kryonaut	0.008	12.5
