Thermal pastes (also known as thermal interface materials or TIMs) are a type of thermally conductive interface material used to fill the gap between two surfaces, usually a heat source and a heat sink, to improve the thermal conductivity between them. Thermal pastes are commonly used in electronics and computing, where heat dissipation from components is important for preventing overheating and component failure. Thermal pastes are also used to improve the thermal performance of some industrial processes, such as injection molding.

They are available in a variety of forms, including paste, liquid, and solid.

Frequently Asked Questions

ARCTIC MX-4 (incl. Spatula, 4 g) - Premium Performance Thermal Paste for all processors (CPU, GPU - PC, PS4, XBOX), very high thermal conductivity, long durability, safe application, non-conductive

Thermal pastes are compounds used to improve the thermal conductivity between two surfaces. Image source: Amazon.com

What are the benefits of using thermal paste?

1. Improved Heat Transfer: Thermal paste helps to fill the microscopic imperfections between a CPU and the heatsink, thereby providing improved contact between the two surfaces and enhancing the transfer of heat.

2. Lower Temperature: Thermal paste helps to reduce the overall temperature of the CPU by providing better heat transfer, allowing the CPU to run at lower temperatures and increasing its lifespan.

3. Cost Savings: Thermal paste helps to reduce the cost of cooling components, as it can be used to replace more expensive materials such as thermal pads and thermal grease.

4. Longer Lifespan: Thermal paste helps to increase the lifespan of the CPU by providing better heat transfer and reducing the overall temperature.

What are the differences between different types of thermal paste?

The main differences between thermal pastes are in the type of material used, the viscosity of the paste, and the thermal conductivity. Common types of thermal paste include silicone-based thermal paste, ceramic-based thermal paste, and metal-based thermal paste. Silicone-based thermal paste is usually the most affordable and provides good protection against oxidation. Ceramic-based thermal paste is more expensive but has higher thermal conductivity, making it better for overclocking. Metal-based thermal paste is the most expensive and has the highest thermal conductivity, making it ideal for high-performance applications.

Does thermal paste expire?

Yes, thermal paste does expire. It will usually last for two to three years before losing its effectiveness.

How often should thermal paste be replaced?

Most thermal paste should be replaced every 1-2 years depending on usage and environment. It's best to check your manufacturer's recommendations for specific details.
