Thermal Grease

Thermal grease is known by a number of names including: CPU grease heat paste heat sink compound or paste thermal compound, gel or paste thermal interface material.It is a thermally conductive material which is usually electrically insulating which helps to dissipate heat from a device. Its main function is to ensure there is no air space between which would act as a thermal insulator. It fills in the microscopic imperfections on the heatsink and device.It is most commonly used between a CPU and a heat sink to maximise heat transfer. It is also used on other electronic components which create heat and also need a heat sink such as MOSFET transistors.There are other types of products to eliminate the air gap under a heat sink: Thermal Adhesive Thermal Gap Pads
