What is thermal paste?

Thermal paste, also known as heat sink compound, thermal silicone grease, high thermal conductivity thermal paste, or chip thermal paste, is a viscous fluid designed to fill gaps between components with uneven surfaces. With a thermal conductivity significantly higher than air, thermal paste plays a crucial role in improving the heat dissipation of electronic components, ensuring optimal performance and preventing overheating.

By filling the tiny imperfections between a heat source and a heat sink, thermal paste enhances the efficiency of heat transfer, making it an essential part of cooling systems for CPUs, GPUs, and other high-performance electronics.
