Thermal Paste Conductivity

Liquid and non metallic compounds have different conductivity levels.

Thermal paste conductivity. Normal non metallic thermal compounds have a thermal conductivity between 4 10 w mk while the liquid metal thermal. You can see that the thermal compound is actually a poor heat conductor and that is exactly the reason why you only need a very thin layer of paste to fill the micro imperfections between. Thermal paste also called thermal compound thermal grease thermal interface material tim thermal gel heat paste heat sink compound heat sink paste or cpu grease is a thermally conductive but usually electrically insulating chemical compound which is commonly used as an interface between heat sinks and heat sources such as high power semiconductor devices. Every thermal paste has a thermal conductivity rating which defines its capacity to transfer heat from the processors to the heat sink.

A thermal paste is made up of filler material suspended in a polymerizable liquid matrix or suspension fluid. With a thermal conductivity of 79 w mk this is one of the best thermal pastes in terms of heat conductivity. More the thermal conductivity the temperature will be reduced more. When it comes to thermal paste arctic mx 4 is probably the most popular compound on the market today due to its impressive thermal performance and great value.

The paste is grease based and includes carbon micro particles which produce high thermal conductivity 8 5 w mk. When the thermal conductivity of a paste is more than the temperature of the components then it s reduced even more. It s conductive so it s not the best thermal paste for gpu usage but it works wonders on your cpu. The filler is a compound or material with a high thermal conductivity that helps in the majority of heat transfer.

This thermal compound comes in a liquid metal form so it s ideal for nickel plated copper heatsinks. A tube of 8 5w mk carbon based compound which is. Higher the thermal conductivity of a thermal paste the better is its performance.
