MX4 vs Kryonaut: How Do They Stack Up?

The main difference between Thermal Grizzly Kryonaut and MX4 is that MX4 thermal paste will last for about eight years before it runs out of optimal effectiveness, unlike its Thermal Grizzly Kryonaut counterpart, which can only be effective for about two to three years.

Building a PC rig or enhancing one is straightforward when you’ve got an effective thermal paste working for you. That’s because heat is a major issue that bugs a lot of systems, slows them down, and reduces their durability.

A normal GPU already has a thermal paste applied, but this will last for a while. And if your PC has been on the shelf for several years, the thermal paste would have gone to nothing by wearing out.

In that regard, you have to replace or apply new thermal pastes on the devices you buy and have those replaced after a couple of years. If you don’t do that, prepare for another wave of overheating.

Now we know you need a thermal paste every couple of years. But the hard part is getting the best to work with or deciding which one to choose from. That’s no small feat considering the vast amount of brands and models to choose from.

If you’re not sure about all that or don’t know much about thermal pastes, you’re in the right place. No two brands and models are the same, with different models boasting different strengths and witnesses. We have two quality options to help you consider – the Grizzly Kryonaut and the MX4.

Keep reading to find out which of them fits your needs.

Thermal Grizzly Kryonaut


  • Simple to clean up
  • Safer than liquid metal
  • Easy to apply
  • Excellent performance


  • Price per gram

The Kryonaut thermal paste is a mildly viscous thermal compound with good stability, making it simple to work with and use. It is one of Thermal Grizzly’s answers to consumers that need reliable, high-quality, and inexpensive ceramic thermal grease.

In line with that, it occupies a strange space between other ceramic pastes and the Thermal Grizzly Conductonaut. What’s more, the Kryonaut is expensive but has a huge advantage over pastes in its class.

Thermal Grizzly’s products have enough quality and are more expensive than the competition. The Kryonaut simply performs better with unique features that make it stand out.

Conductivity: Very High and Easy to use

If you’re looking for a paste that comes with extremely high conductivity, this is it. Its conductivity is rated at 12.5KW, which is achieved with smaller particles and is ideal for even the most demanding configurations.

It can also be used in industrial cooling systems.

The best part?

This thermal compound paste is easy to use, thanks to a uniquely constructed syringe and spatula for spreading thermal grease. It helps you achieve a simple, pleasant, and precise distribution of the paste on your processor or graphics card.

Performance: Quality Lasting Effects

If you want long actions on your PC and CPU, look no further than this paste from Thermal Grizzly. You’ll get a long-lasting effect due to its characteristic and specialized structure.

We noted that the Kryonaut thermal paste does not dry out even at 80 C. It will deal with the loudness of your equipment and improve the comfort of use.

While the temperature difference between the Thermal Grizzly Kryonaut pastes and the other ceramic pastes is small, those few degrees can make a massive difference if you overclock. Even if you push your PC’s performance, this Kryonaut will genuinely show its usefulness.

Are you searching for the best possible performance from a thermal grease or paste and want to overclock?

This paste is the best for overclocking. Our Thermal Grizzly Kryonaut review further shows that it’s up there with the best liquid metals. You can apply both to get the best out of your PC.



  • Easy to install
  • Long-lasting quality and efficiency
  • Excellent performance


  • A bit low shelf life

If you’re familiar with the Arctic brand, the Arctic MX4 thermal compound should also ring a bell. The MX-4 doesn’t need any introduction as one of the foremost thermal pastes the world over.

The brand has built a strong reputation from the onset for producing quality products, and thus thermal paste offers a consistent benchmark that beats its competitors. That’s why it’s an excellent choice for a variety of users.

Design: Proven Quality

The Arctic MX4 is a paste worth trying if you’re looking for proven quality. Also, packaging from the Arctic has changed over time, but the formula composition has remained steadfast.

As a result, there’s no reduction in quality from the brand and its products. That means high durability in contrast to metal and silicon thermal compounds. The MX4 won’t compromise, and once applied, you don’t need to do so again for at least eight years.

Performance: Leave You Satisfied

We have mentioned that the MX-4 does better than metal, and one of the reasons is that it doesn’t contain metallic particles. Instead, this paste is made of carbon microparticles, guaranteeing extremely high thermal conductivity.

It will ensure that heat from the CPU/GPU is dissipated quickly & efficiently. Also, it makes direct contact with every pin on your CPU, with your only worry is having to clean it up. There’s very little chance of the liquid getting spilled, thanks to the soft consistency of the paste.

In addition, the MX4’s performance is rated to last over a long time. It comes in a 0.64-ounce tube designed to produce enough thermal paste for many applications.

However, its relatively low shelf life means you shouldn’t hold on to an extra paste. You can be confident that you’ve successfully installed your cooler.

There’s seldom any difficulty when it comes to installation. It’s smooth and consistent. Even if you don’t have adequate experience applying thermal pastes, you won’t be exposed to too many risks.

It’s a simple design application tube that won’t adversely affect your hardware. It’s safe and adds more protection to the CPU and VGA cards.

Our mx4 thermal paste review shows that it’s still one of the best out there by providing excellent thermal transfer at an attractive price. That’s why it’s the perfect thermal compound for new users and those on a budget. Its consistent design makes it easy to apply and clean.

Head-to-Head Comparison of Top Features

It’s never easy to make a thermal paste comparison whenever two quality products are on display, especially from established brands. But we made a couple of distinctions between these two.

Viscosity and Ease of Installation

Winner: Both 

Some minor and major issues could occur when installing a paste or compound. One of them is the danger of electrical conductivity. What’s more, some pastes are more challenging to apply than others.

So even if you’re an experienced user, you’d want to know a thing or two about the viscosity of a paste before you apply it. Understanding the viscosity involved can also help to determine whether you’ve squeezed out the right amount of paste or not.

Application of the past also matters. The wrong technique could affect your CPU. Note that for installation, the Kryonaut and MX4 are simple to apply.

You’ll find that thicker pastes tend to be more challenging to apply. However, as long as you’re attentive to the viscosity of any paste you choose, you can prepare for installation by searching for the appropriate application method.

If you’re installing thermal paste on one or two processors, don’t worry about their tube content. The fact is almost all thermal paste tubes on the market will have enough paste to install a CPU.

But if you’re doing more than a single installation, take notice of the quantity of paste you get on purchase. Manufacturers like the Arctic put in enough to cover two systems.

Thermal Paste Lifespan

Winner: MX4

It’s okay to consider the quantity of the thermal paste that comes with a tube, but don’t get ahead of yourself on the number of years you can get from it. That’s because the shelf life of many pastes is just two or three years. That applies to both of these pastes.

Also, it’s common knowledge that thermal pastes don’t age well. For this reason, many people squeeze and use them, throw what’s left of the tube, and paste away. However, the main thing is what happens after applying the paste.

When applying the Thermal Grizzly Kryonaut to your system, you can expect it to be effective for about two to three years. On the flip side, according to the Arctic brand and reviews from previous users, the MX4 will last for about eight years before it runs out of effectiveness.

But many manufacturers suggest replacing a paste every two or three years max. Don’t worry about that, though. Even after those three years, the paste will still perform adequately, but not as they were at first.


When it comes to power and overall performance, we’ll stick to the MX4 even if it’s older than the Thermal Grizzly Kryonaut. That’s because it’s cheaper, offers more protection, and will last for up to eight years in your system.

The Kryonaut is great, but it’s more expensive and doesn’t offer much else to suggest it’s better than its counterpart.

While the MX4 tube does not provide enough paste for several applications, it’s more than enough to complete two separate processors and still have a leftover paste. Overall, our team will recommend the MX4, as we believe it is best for those who want a safe, budget-friendly, and reliable solution.
