Thermal Grease-The Best Partner For CPU

What is Thermal Grease?

Thermal grease, also known as thermal paste, is a thermal interface material used between high-power electronic component and heat sink. It has excellent thermal conductivity and good reliability. The perfect wettability allows it to quickly fill the micropores of the interface, greatly reduce the interface thermal impedance, and quickly and effectively reduce the temperature of electronic components, thereby extending the service life of electronic components and improving their reliability. CPU is a typical application case.

Features & Benefits

High thermal performance; Ultra low thermal impedance,can press to 0.1mm thickness; Wettability and electrical insulation; Good thixotropy and easy operation; Low sedimentation, excellent chemical and mechanical stability;

Typical Applications

Between CPU and heat sink; LED lights; Notebook and desktop computers; Power device; Communication device; Automotive engine control module

Silicone grease mainly plays a role in heat conduction, but the thermal conductivity is still not as good as that of direct metal contact, which means that the silicone grease should only fill the gap between the CPU and the heat sink, and it does not need to be applied too much to avoid affecting heat dissipation.In addition, the radiator will squeeze the silicone grease during the pressing process, too much silicone grease may flow from the gap around the CPU to the motherboard, affecting the use. The uniform and appropriate thickness of silicone grease can fill the gap between the heat sink and the chip, make it more closely contact, increase the heat dissipation area, and improve the heat dissipation effect.
