Thermal paste is a substance used to improve the heat transfer between a computer processor and its heat sink. It fills in microscopic gaps and imperfections on the surfaces of these components, ensuring better contact and reducing the risk of overheating. Proper application of thermal paste can enhance the performance and longevity of electronic devices. Typically made from materials like silicone or metal oxides, thermal paste is essential for maintaining optimal operating temperatures. Over time, it can dry out or degrade, necessitating reapplication. Regular maintenance of thermal paste can help keep systems running efficiently and prevent thermal throttling.
