Non-silicone heat transfer compound Super Thermal Grease II 8616 MG ChemicalsThe 8616 Super Thermal Grease MG Chemicals is low thermal resistance grease with a synthetic oil base that is electrically insulating and non-corrosive. It is use to improve the thermal interface contact conductivity between heat sinks, LEDs, motors, and heat-generating electronic components such as CPUs, GPU chipsets, power components, and so on. It improves the thermal interface between irregular and pitted surfaces. High thermal conductivity Silicone Free and non-bleeding Lowers the contact resistance between irregular surfaces Extends the life of electronic components High dielectric strength Safe on plasticsIt is important to properly cool your system for maximum reliability and to prevent premature failure.Heat sinks alone are not effective enough to properly cool your system do to the imperfections on the surface of your circuitry and the heat sink.
