You might already be aware of the fact that a CPU and GPU of a computer system generate a lot of heat…

…and the cooling fans in the system help keep the temperatures low.

Similarly, another effective method is used to cool down the processing units of a computer.

Best Thermal compound 2022


It is by applying “thermal paste” on the processing units so it helps in keeping the temperatures low.

If you use your computer a lot, you might notice some fan noise, especially when doing any processor-intensive work. That is because the computer is trying to cool down the graphics cards and processors, so it doesn’t lag and performs optimally.

This guide will list the best 11 high-quality thermal compounds you can get to improve and increase the lifetime of your computer.

Some of you might wonder what a thermal paste or thermal compound is?

It seems a bit “nerdy,” but it plays a vital role in keeping your computing system healthy by helping to improve heat conduction.
The paste is applied between the component it is meant to cool and the heatsink.

Generally, CPUs and GPUs come with pre-applied thermal compounds but are usually a bit old. Therefore, it is recommended that you should know how to apply thermal paste by yourself once you set up your gaming/computing station. 

You must reapply thermal paste once a year as once it dries out, it becomes less effective. Not applying thermal paste can cause your CPU to heat up and affect the overall performance.

Top 10 Best Thermal Pastes/Compounds in 2023

Thermal pastes come in two different forms:

  • Conductive Pastes
  • Non-Conductive Pastes

The inferior one among these is the non-conductive thermal compounds which include zinc and silicone thermal greases.

Alternately, the superior ones are the conductive thermal compounds which include copper, silver, and aluminum-based pastes.

However, these can induce electrical shorts if applied to electrical pathways on the circuit board or the microprocessor’s pin.

Therefore getting the best thermal compound is essential to keep your gaming laptop or gaming pc performing well and at lower temperatures.

So, without any more wait, let us look at the best thermal pastes for your CPU/GPU that you can get in 2023.

The Ultimate
Buyers Guide

Many people do not understand the importance of keeping the temperatures of your computer system low.

It helps increase the efficiency and the overall life span of the processor.

Generally, people who know about these thermal compounds get them. But still, they do not get the “best” one according to their needs. 

buyers guide for thermal compound

There are some key factors that you need to keep in mind when choosing the best thermal compound. These may vary from person to person.

However, there are around four essential aspects that you need to keep in mind. These are density, volume, storage time, and thermal pastes/compound types

For your assistance, I have divided this buying guide into four subsections which cover the essential aspects. Then, there is a fifth bonus point for some extra things that you might have to consider. 


As you might already know, in simpler terms, density is the thickness of a substance.

You might wonder how vital density is when choosing the best thermal compound. Well, it is pretty simple. The denser the thermal paste is, the better it will work. They are thick and gooey and conduct heat much better.

If you are a beginner, you should use a less-dense thermal compound. They are easier to apply as compared to dense ones. If you are a professional and like to take things to the max, you should go for a thicker thermal compound. It will conduct more heat and help keep the temperatures low.


Volume is another vital factor to consider when buying a thermal paste. It is directly related to how much your usage is.

If you want to apply the thermal paste on your Intel & AMD CPUs, you should go for a thermal compound with a lesser volume. On the other hand, if you work on multiple projects, you have to choose one with more volume.

Some of you might wonder why you shouldn’t buy one and reuse it later if it is leftover? The answer is straightforward. You can not use the same thermal compound once it has been opened and used.

Typically, these thermal pastes expire a couple of months after they are opened. However, a single application on a component lasts for several years. 

In a nutshell, the paste is useless in a few months once the container opens. Therefore, you need to buy only as much as you require. Typically, half a gram is adequate for personal use on a single project.

If you have multiple projects, a total volume of 3.5g-4g is what you are looking for in the paste.

If you are confused about how much Thermal Paste I should apply to my CPU, then you should read this guide by Gamers Nexus.

Storage Time

Many people keep extra stuff lying around, so they do not have to rush to get them at the last minute. Similarly, if you are the same type of person, you need to see the storage time before considering keeping one at home.

It is highly recommended that you keep a paste with a storage life of at least two years.

Also, if the compound dries out, it loses its cooling properties. Make sure you do not add a dried-up paste to the processor, as it can severely damage it.


As I mentioned earlier in this article that there are two main types of thermal compounds:

  • Conductive Pastes (Silver, Aluminum, Copper, etc.)
  • Non-Conductive Pastes (Ceramic, Silicon, Zinc, etc.)

You need to choose the type of thermal paste you need very carefully. Commonly, conductive compounds are a better option, but it is still entirely your choice. 

To help to choose the best type, here are a couple of Pros and Cons of conductive compounds:


  • More durable than non-conductive pastes.
  • Slightly better performance than non-conductive pastes.


  • These are more corrosive.
  • Comparatively more expensive.

On the other hand, non-conductive compounds are cheaper and non-corrosive too. They do not perform as well but get the job done for an average joe.

Bonus Tips

  • Ease-of-Use: If you are a beginner, you must see how easy it is to apply the thermal paste and whether it includes and helping materials too or not.
  • Clean-Up: Although the re-application of thermal paste takes place after years, it is still essential to consider how easy it is to clean it so that you can apply the paste once again.
  • Reviews: READ THE REVIEWS! Users reviewing how well the product works helps when choosing the best one. 
  • Lifespan: For obvious reasons, you need a thermal paste that will last longer and keep things cool without changing it every once in a while. Hence, notice the thermal compound’s lifespan before choosing it.
  • Price: Though not much significant as they all cost less than $20, it is still worth considering along with other factors. You have to spend on something worth the price. You need to get value for the money that you give.
