syringe of thermal paste, also known as thermal grease or heat sink compound. 

syringe of thermal paste, also known as thermal grease or heat sink compound. It is primarily used to improve heat transfer between electronic components like CPUs, GPUs, and their respective heatsinks.

Purpose:

Eliminates air gaps between heat sources and heatsinks to maximize heat dissipation and prevent overheating.

Application:

Commonly applied to computer components like CPUs, GPUs, chipsets, and other heat-generating devices.

Properties:

High thermal conductivity, high insulation, high-temperature resistance, and often non-toxic and non-corrosive.
