The frequency of replacing thermal compound in a desktop PC depends on various factors, including the quality of the initial application, the type of thermal compound used, and environmental conditions. In general, it’s recommended to replace thermal compound every 2-3 years to maintain optimal thermal conductivity.
Over time, thermal compounds can dry out or degrade, leading to reduced efficiency in heat transfer between the CPU and the heatsink. If you notice higher temperatures or reduced performance, it may be a good time to replace the thermal compound. Regular cleaning and reapplication can help ensure the longevity and efficiency of your PC’s cooling system.
