Thermal compound, also referred to as thermal paste or thermal interface material (TIM), is a viscous substance utilized to improve the thermal interface between a heat-producing device, like a GPU or CPU, and a heatsink. It is applied as a thin layer between the surfaces to fill in microscopic imperfections and air gaps, thereby facilitating better heat transfer. Thermal compounds are typically composed of silicone-based, ceramic-based, or metal-based formulations, each offering varying levels of thermal conductivity and viscosity. Unlike thermal pads, which come in pre-formed shapes, thermal compound application requires careful spreading to ensure uniform coverage and optimal contact between the surfaces. While the application process may be messier compared to thermal pads, thermal compounds are favoured for their superior thermal conductivity, making them ideal for high-performance computing systems and overclocking applications.
