10 Best Thermal Pastes 2024 (Updated)

Do you know a CPU/GPU running at high-temperature results decrease in performance?

So for ideal performance, you need to make sure that the heat conduct through CPU or GPU to heatsink/cooler. For heat conduction, you need to apply the thermal grease on the processor. Buying not only a better quality thermal compound is imperative but also applying it in the right manner. Moreover, the selection of best thermal paste also depends on your use like for over gaming pc or overclocking the consideration might be different for average users.

Well, you are at the very right place where we can help you to understand all types of compounds, what our recommendations are and how to apply it correctly.

Do not confuse between following terms like thermal grease, CPU grease, thermal compound, heat sink paste, thermal gel or thermal gunk, all of them are same and used interchangeably.

Types of Thermal Pastes

First off, you need to know different types of pastes which is helpful for better understanding and decision making. The thermal grease can mainly categories into two types “Conductive” and “Non-Conductive”. The non-conductive type usually includes zinc and silicone while conductive type contains copper, silver aluminum substances.

Applying a non-conductive mixture is really easy even if you are dealing with it for the first time in your life. But with Conductive thermal compound, you should take some extra care while applying because these are electrically conductive and contact with any metal component on the motherboard or with microprocessors pins can cause damage. Don’t be worry about this as we will guide you through how to apply the paste in right manners.

Metal-based greases are much efficient when compared to non-metal, therefore, good for overclockers and hardcore gaming PCs. Also usually slightly cost higher than zinc or silicon-based compounds.

How Thermal Compound Works

There are chances where process surface and heatsink are connecting properly. The contacting surfaces may look pretty flat but in reality, these are rough when observing through the microscopic eye. So here thermal compound used as a medium so to transfer the heat efficiently from processor to heatsink or cooler. That is why thermal grease usually includes ingredients such as silicon and zinc etc.

How to Remove the Thermal Paste

So if you just buy a new processor then skip this step otherwise if you are re-applying the thermal gunk, then you need to remove the previous material for re-application.

Removing paste is an effortless process you just need 99% isopropyl alcohol. Simply pour some isopropyl alcohol on a small piece of clean fabrics and then carefully wipe out the compound.

How to Apply Thermal Paste?

There are multiple methods to apply the TIM such as Pea, X, Spread, Dot, and Line etc. Although every method results in almost the same performance, the thing you need to care that not to put too much quantity or too less.

The compound can be spread over the processor surface or you can put a dot and when you press the cooler or heatsink over it will automatically spread. Also, for making application easier, some manufacturer even offer facilitating tools like spreading stick.

Another good method is to pour a line or an X that will surely do its job. Here keep in mind that the heat outflow also depends on the cooler or the heat sinks.

Now without further ado let’s move on to the best thermal pastes available in the market.
