860 is a cpu thermal paste designed to reduce thermal resistance between irregular metal surfaces. Coupled with reasonable thermal conductivity, 860 has a soft consistency and a wide operating temperature range, which in some instances makes it the best thermal paste for cpu applications.

This silicone-based pc thermal paste is mostly used to improve heat flow between heat sinks and heat-generating components, such as CPUs, GPUs, LEDs, motors, and power components.
