Thermal paste reapplication for blockchain mining equipment involves removing the old or degraded thermal paste from the chips and heatsinks and applying a fresh layer of high-quality thermal paste. This process improves heat transfer between the chips and their cooling components, allowing for more efficient dissipation of heat during operation. Proper reapplication ensures that the equipment maintains optimal temperatures, preventing overheating, enhancing performance, and prolonging the lifespan of the hardware by keeping it cool under heavy hashing loads.
