If you are PC enthusiast or PC gamer then you probably are well aware of Thermal Pastes, what are they and why are they used. But for those who are planning to build a gaming PC and want to know about Thermal Pastes, it is a thermally conductive compound that we use as an interface between heat sinks and heat sources. As we all know that running a computer processor too hot reduces its longevity, so we use CPU coolers.

Usually, thermal pastes come along with CPU coolers but are they the best ones? This we will discuss further. Often, thermal paste is used to fill the air gap between CPU and Cooler; this fastens the heat transfer between CPU and Cooler, which keeps your CPU cool.

10 Best Thermal Paste for CPU You Can Buy in 2021

Now if you are confused that which thermal paste you should use for your PC, here are some best thermal paste for you:

1. Arctic MX-4

Best Thermal Pastes

Arctic MX-4 Thermal Compound is one of the most famous thermal paste in the market. It is composed of micro carbon particles that make it extremely heat conductor. Its 8.5W/mK thermal conductivity keeps it right next to the GC-Extreme Thermal Compound as no metallic particle is used in Arctic MX-4, hence no issue of electrical conductivity. The manufacturer claims that once Arctic MX-4 is applied, it will last at least eight years and its performance does not compromise over time. It is cheap and durable for overclockers and enthusiast.

2. Thermal Grizzly Kryonaut

Best Thermal Pastes

If you are planning to build a hardcore PC, then you should probably use Thermal Grizzly Kryonaut. Grizzly Kryonaut helps you to increase your CPU performance to its maximum by overclocking. It is the best non-captive grease in the market. Although its price is so much high as we all know “quality comes with the heavy price.” Thermal Grizzly Krynout delivers what it promises. With its 12.5W/mK thermal conductivity, it provides the maximum heat towards cooler and does not conduct electricity. This thermal paste uses a unique structure which halts the drying out process at temperatures of up to 80° Celsius.

3. Gelid Solutions GC-Extreme

Best Thermal Pastes

Gelid Solutions GC-Extreme also stands among the best thermal paste but after Thermal Grizzly Kryonaut. The main difference between Gelid Solution GC- Extreme and Therma Grizzly Kryonaut is thermal conductivity. Gelid Solution GC-Extreme offers 8.5W/mK thermal conductivity, not well as Thermal Grizzly Kryonaut but still good to give a hard time to other competitors. Its Non-Electrical, Non-Corrosive, Non-Curing and Non-Toxic feature keep your CPU cool and smooth. Lastly, it is much cheaper than Thermal Grizzly Kryonaut.

4. Arctic Silver 5

Best Thermal Paste for CPU

It’s not long enough when Arctic Silver 5 thermal Pate was considered one of the best thermal for providing the best performance for the time. With the advent of new thermal paste, it Arctic Silver 5 has been outperformed. But still, with its 8.7 W/mK thermal conductivity, it beats GC-Extreme as well as Arctic MX-4. Some of the enthusiasts still prefer Arctic Silver because of its 99.9% pure micronized silver technology. Non-Electricity conductivity makes it stable and long-lasting.

5. Cooler Master MasterGel Maker Nano

Best Thermal Paste for CPU

After a short break, cooler master has come back to the industry with a blast. MaterGel Maker Thermal Paste provides 11W/mK thermal conductivity that outruns the GC Extreme Thermal Compound. With its Non-curing and Non-Electrical trait, it helps in avoiding short-circuiting and increases its performance. As Cooler Master Claims that its nanodiamond particles in the paste are capable of handling temperature from -50 to 150 ℃, lastly, if you want to overclock your K series CPU, this might be the best thermal paste.

6. Noctua NT-H1

Best Thermal Paste for CPU

For exceptional performance and ease use enthusiast might prefer Noctua NT-H1. Usually, Noctua NT-H1 comes along with Noctua’s premium coolers but if you want to buy it separately, you can. The manufacturers claim that NT-H1 consists of different micro-particles that allow for minimum thermal resistance and maximum long-term stability. However, its thermal conductivity has not been disclosed by the manufacturer. But still, its peak operating temperature is -50 to 110 ℃. Due to its low price some over-clocker still uses NT-H1.

7. Coollaboratory Liquid Ultra

Best Thermal Paste for CPU

Now this one is for the extreme enthusiasts. If you haven’t found any interesting Thermal Paste yet, this might be the one you are looking for. As enthusiast turn towards the best cooling results and also liquid cooling is better than air cooling, Coollaboratory Liquid Ultra has given both to them. Coollaboratory Liquid Ultra along with its liquid metal based compound offers 38.4W/mK thermal conductivity works best on delidded CPUs. Precaution for using Coollaboratory Liquid Ultra is that it should not be used with aluminum heatsinks, as it will destroy your aluminum sink. Once you use Coollaboratory Liquid Ultra, you will notice a significant temperature drop.

8. Thermal Grizzly Conductonaut Liquid Metal

Best Thermal Paste for CPU

Last but not the least, Thermal Grizzly Conductonaut Liquid Metal Compound stands first in the list of thermal pastes. You might need this if you only want the best Thermal Compound. The manufacturer has targeted the enthusiasts that plan to overclock their PC by delidding. With its extremely insane thermal conductivity of 73W/mK, Thermal Grizzly Conductonaut Liquid Metal Compound is capable of keeping the temperature in check. With this much thermal conductivity, Thermal Grizzly Conductonaut Liquid Metal Compound is used where there is a critical heat dissipation problem, and even 1℃ difference is valuable. But that doesn’t mean that you cannot use it in your PC. If money is not a problem for you, grab one for yourself.
