Factors to Consider When Choosing a CPU Thermal Paste
When selecting the best CPU thermal paste for your system, there are several key factors to consider. The right thermal paste can make a significant difference in your system’s performance and longevity. In this section, we will discuss the most important factors to consider when choosing a CPU thermal paste.
Thermal Conductivity
Thermal conductivity refers to the ability of a material to transfer heat. In the context of thermal pastes, thermal conductivity is measured in Watts per Meter-Kelvin (W/mK). The higher the thermal conductivity of a thermal paste, the better it will be at transferring heat away from the CPU. When choosing a thermal paste, look for one with a high thermal conductivity rating. Some popular thermal pastes have thermal conductivity ratings of over 10 W/mK.
| Thermal Paste Name | Thermal Conductivity (W/mK) | Viscosity | wetting properties |
|---|---|---|---|
| Noctua NT-H1 | 8.5 W/mK | 10000 mPa.s | Excellent |
| Thermal Grizzly Kryonaut | 12.5 W/mK | 10000 mPa.s | Excellent |
| Arctic MX-4 | 8.5 W/mK | 110,000 mPa.s | Good |
| Coollaboratory Liquid Ultra | 13.5 W/mK | 10000 mPa.s | Excellent |
Viscosity
Viscosity refers to the thickness or flowability of a fluid. In the context of thermal pastes, viscosity is measured in centiPoise (cP) or milliPascal-seconds (mPa.s). A thermal paste with high viscosity will be thicker and more resistant to flowing out of the gap between the CPU and the cooler. On the other hand, a thermal paste with low viscosity will be thinner and more prone to flowing out of the gap.
Wetting Properties
Wetting properties refer to the ability of a liquid to spread and adhere to a solid surface. In the context of thermal pastes, wetting properties are important because they affect the ability of the paste to fill the gap between the CPU and the cooler. A thermal paste with excellent wetting properties will be able to spread easily and fill the gap, while a thermal paste with poor wetting properties may not be able to fill the gap effectively.
When choosing a thermal paste, consider the viscosity and wetting properties in addition to thermal conductivity.
