Thermal paste (-4.5W)

Thermal Paste -4.5W is a high-performance silicone-based thermal grease designed for high-end CPU, GPU and custom chip assembly. Due to its excellent wetting properties, the thermal paste -4.5W can fill the microscopic irregularities on the surface of the component, thereby achieving extremely low thermal resistance.

Product characteristics

The thermal paste -4.5W has stable performance and will not dry up, precipitate or harden. Thermal paste -4.5W easy to use, suitable for customers to operate.
