👉 Motherboard fluid, also known as thermal paste or thermal compound, is a specialized liquid used to enhance heat transfer between the CPU and the motherboard's heat sink. It fills microscopic gaps and imperfections on the surface of the CPU and heat sink, ensuring efficient thermal conductivity and preventing overheating. This fluid acts as a bridge, allowing for better heat dissipation and maintaining optimal operating temperatures for the components. While not as commonly discussed as other aspects of motherboard maintenance, using the correct type and applying it properly is essential for the longevity and performance of the system.
