Thermal Paste Conductivity

Each thermal paste comes with its own thermal conductivity rating for how efficient it is at transferring heat from the processor to the heatsink.

Thermal paste conductivity.

Every thermal paste has a thermal conductivity rating which defines its capacity to transfer heat from the processors to the heat sink. This thermal compound comes in a liquid metal form so it s ideal for nickel plated copper heatsinks. More the thermal conductivity the temperature will be reduced more. Price is normally set based upon thermal conductivity and the amount of compound in the tube generally in the range of 3g which is a few uses.

Higher the thermal conductivity of a thermal paste the better is its performance. Liquid and non metallic compounds have different conductivity levels. It s conductive so it s not the best thermal paste for gpu usage but it works wonders on your cpu. With a thermal conductivity of 79 w mk this is one of the best thermal pastes in terms of heat 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. For example the thermal conductivity of a high grade thermal paste is 8 5 w mk and the heat conductivity of copper is 385 w mk or for aluminum 205 w mk. 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.

When the thermal conductivity of a paste is more than the temperature of the components then it s reduced even more. The filler is a compound or material with a high thermal conductivity that helps in the majority of heat transfer. A tube of 8 5w mk carbon based compound which is.
