👉 Laptop fluid, also known as thermal paste or heat spreader paste, is a specialized lubricant applied between the CPU (Central Processing Unit) and the motherboard's heat sink to enhance thermal conductivity. This paste fills microscopic air gaps, creating a more efficient pathway for heat transfer from the processor to the cooler surface of the heat sink. By improving heat dissipation, laptop fluid helps maintain optimal operating temperatures, ensuring the CPU functions efficiently and prolongs its lifespan. The paste typically requires periodic reapplication as it degrades over time due to heat and usage, maintaining its effectiveness in managing thermal performance.
