Introduction to Gap Pad
Gap pads are thermal interface materials (TIMs) used to fill the gaps between heat - generating components (such as CPUs, GPUs) and heat sinks. They play a crucial role in enhancing thermal conductivity, which is essential for efficient heat dissipation. By filling the microscopic air gaps at the interface, gap pads can significantly improve the transfer of heat from the heat source to the heat sink, thus preventing overheating of electronic devices and ensuring their stable operation.
