Only true gamers and power users know the importance of efficiency. To keep a CPU efficient and optimal for performance, you need to keep it cool.

One of the items that help in keeping a CPU and mainly the processor cool is thermal paste. Let me tell you one thing right away, YES! The best thermal paste is going to increase your CPU’s performance significantly.

In this article, we are going to list down the best thermal paste you can buy in 2021. So if you are looking for thermal pastes, you probably came to the right place.

What is a Thermal Paste and Why People Use Them?

If you aren’t a performance-heavy user who uses a custom-built PC, chances are you have never heard about thermal paste. Well, it is a soft paste-like compound that is thermally conductive.

It is placed between the processor and the heat sink to eliminate all the air gaps between them. The paste itself helps a lot in keeping the CPU or GPU temperatures low as it conducts the heat from the processor to the heat sink.

As a result, the CPU is generally cooler and every one of you knows how important it is to keep your CPU temperatures low.

Not only it boosts the performance capabilities, but it is low operating temperatures also ensures the longevity of your CPU or GPU.

Now, a lot of processors come with pre-applied thermal paste but it is nothing compared to the best thermal paste you will find here on the list.
