Thermal Grizzly Kryonaut

Thermal Grizzly Kryonaut

31pzT95fepL. SL160


  • Exemplary Thermal Conductivity
  • Supreme Cooling Efficacy
  • Non-Corrosive Formulation
  • Seamless Application

I strongly recommend Thermal Grizzly Kryonaut as the best thermal paste on the market for Overclocking enthusiasts.

It is the top-rated ceramic Thermal Paste for Overclockers, costing twice as much as the other carbon-based pastes.

As you’d expect, this product is non-capacitive and electrically neutral. You don’t have to go through any break-in period, so it’s easy to apply to your CPU surface.

With a thermal conductivity rating of 12.5 W/mK, the Thermal Grizzly Kryonaut is sold in 1 gram packages with a reasonable usage period of 3 to 4 applications. 

This is undoubtedly one of the best thermal pastes for both CPU and GPU overclocking.

What I like about this thermal paste 

  • High thermal conductivity
  • Low thermal resistance
  • Non-electrical conductive

What I don’t like about this thermal paste

  • Expensive compared to other thermal pastes
  • Can be difficult to spread due to its viscosity
  • Short shelf life compared to other thermal pastes.

Noctua NT-H1

Noctua NT-H1


  • Zero Curing Properties
  • Effortless and User-Intuitive Application
  • Unwavering Thermal Stability
  • Exceptional Thermal Conductivity

If I recommend a reliable Carbon Thermal paste for Overclocking, then it has to be the Noctua NT-H1.

To begin with, the better performance of this paste that was not sacrificed for its incredibly affordable price point is enough to pique your interest.

It has quickly become a popular choice in the thermal paste market, particularly for Overclocking enthusiasts and hardcore gamers.

The Noctua NT-H1 offers a thermal conductivity of 8.5 w/mK, and a pack weighs 3.5g. This is not impressive when you compare it with the packaging of the Arctic MX-4 and Arctic Silver 5, but the Noctua NT-H1 does a job of cooling your PC, no matter the situation.

What I like about this thermal paste

  • Popularity 
  • Low thermal resistance
  • Long-lasting and durable
  • Easy to apply

What I don’t like about this thermal paste

  • May not perform as well as other thermal pastes in certain applications or with certain hardware configurations

Arctic MX-4

Arctic MX-4

31uLVhkzBOL. SL160


  • Long-Term Performance Stability
  • Non-Curing,
  • Non-Conductive
  • Effortless Application

No matter how far you push your PC components, the Arctic MX-4 is another carbon-based compound that is sure to meet the required cooling needs.

The paste stands out from the crowd, particularly for its low pricing, easy application, and high performance. 

With a syringe design, you will have no problem applying this thermal paste, which is why I recommend it for people trying a thermal paste for Overclocking for the first time.

Unlike the Arctic Silver 5, which is formulated with 99% micronized silver and takes time to settle down, the MX-4 needs no time to settle down.

In terms of price, this is a worthy alternative to the Noctua NT-H1 but will most likely contend head-on with the thermal grizzly Kryonaut in terms of performance.

What I like about this thermal paste

  • Long-lasting durability
  • Fluidity for easy spreadability

What I don’t like about this thermal paste

  • May require a longer “burn-in” period to achieve optimal performance
  • May be slightly more expensive than some other popular thermal pastes.



41OgUyO87NL. SL160


  • Optimal Heat Conductivity
  • Corrosion-Resistant
  • Simple to Apply
  • Sustained Performance

Another quite impressive thermal paste that has the reputation of withstanding Overclocking and rising to the occasion is the Corsair TM30.

The thermal paste compound needs no introduction, especially if you’ve spent enough time in the gaming PC industry.

First of all, this paste is designed to last for years without breaking or changing consistency. So longevity is good value for money. (Similar to the MX-4, that lasts for 8 years.)

This is a good option if you don’t want to replace your paste often. The chemical stability and low viscosity of the paste are also worth considering because they deliver the right contact with your components by filling microscopic abrasions for peak thermal transfer.

What I like about this thermal paste

  • Does a good job of cooling your CPU and GPU
  • Ultra-low thermal impedance lowers CPU temperatures, making it superior to regular thermal paste.
  • The package comes with an included application stencil and spreader for easy application.

What I don’t like about this thermal paste

  • There are other options with similar offerings but offered at a slightly lower price tag

Thermal Grizzly Conductonaut

Thermal Grizzly Conductonaut



  • Utilization of Liquid Metal
  • Outstanding Heat Conductivity
  • High-efficiency cooling
  • Tailored for Enthusiasts

The thermal Grizzly Conductonaut is popularly known as one of the best capacitive thermal pastes for overclockers.

It is a metal-based thermal compound that is formulated with high-end heating compounds.

Pure liquid metal is electrically conductive, which means, unlike all the options reviewed above, you will need more attention during application so it doesn’t damage components due to spills.

Meanwhile, this is one of the best options to look at if you plan to take your processor up to its overclocking limits.

With an impressive thermal conductivity rating of 73 W/mK, the thermal paste is a great option for overclocking and can help you easily achieve up to 10 degrees Celsius of temperature regulation.

What I like about this thermal paste

  • Impressive thermal conductivity
  • Longevity and durability

What I don’t like about this thermal paste

  • Highly conductive and electrically conductive
  • Requires careful application to avoid short circuits
  • Can corrode certain metals over time

Wrapping up

I believe overclocking isn’t a deal-breaker since we now have computer components that are so powerful that they make no difference in handling demanding applications.

But for core gamers and ultra-power-starved PC users, Overclocking is a necessity to achieve peak performance while playing a game or working.

Applying a good thermal paste is the best preventive measure against the dark side of Overclocking.

The products reviewed in this article are solid options to ensure your PC components will last for a long time.
