A CPU thermal paste is also known as a thermal grease, a thermal gel, a heat sink compound, or a gray goo! It’s an essential thing for the CPU and heat sink installation. There are many brands in the market providing thermal pastes and claiming for the best. But, there are slight differences between them except a thermally conductive filler and a polymerizable liquid with an electrical insulation they consist, which make them stand out from one another. In the above list of the “Thermal Paste for CPU”, I have tried to include all of the top heat sink compounds available in today’s market. If you have any suggestions or query, then you can make a comment below. With the help of the best CPU thermal paste, you will create a strong and non-conductive bond between any chip and heat sink.
