According to my benchmark test results, the Thermal Grizzly Kryonaut is the best thermal paste for the Ryzen 5 5600X. It is a high-performance thermal paste known for its excellent heat transfer properties and long lifespan. It is a bit more expensive than other options, but it is worth the investment of severe overclockers.
While there are discrepancies about this chip in terms of price, many users are having issues with the correct thermal paste to buy for the Ryzen 5 5600X to replace the thermal compound pre-applied on the contact surface of the AMD box cooler.
So it is not enough to have a midrange productivity and gaming computer. Getting the right thermal paste with reliable cooling performance is another aspect that requires critical decision-making.
Fortunately, I have combed through and reviewed a score of highly-rated thermal pastes for the Ryzen 5 5600X board and have narrowed the best-performing compound paste to these five products below.

Suppose you are looking for the best thermal paste for your Ryzen 5 5600X. In that case, I recommend that you look into any of the following products because they outperform most other products in terms of longevity, reliability, performance, and affordability.
- Arctic MX-6
- Thermal Grizzly Kryonaut
- Cooler Master MasterGel Maker
- Gelid Solutions GC-Extreme
Here’s why they are the best:
Arctic MX-6
Arctic MX-6
Arctic MX-6 is undoubtedly one of the best thermal paste compounds used with any processor and is not limited to the Ryzen 5 5600. It is known for its low viscosity, which ensures easy and smooth application to the surface, and it’s made with a mixture of non-hazardous solutions.
Being the latest thermal grease in the Arctic thermal paste lineup, the MX-6 is a fantastic combo of Arctic’s MX-4 and MX-5 thermal conductivity and heat transfer. Still, there’s no massive difference in allocation method or packaging.
What makes the Arctic MX-6 stand out is its thermal performance. I also noticed an improvement in the spreading on the CPU, which is much easier than when using the two predecessors.
I would recommend this thermal paste repeatedly to anyone looking to max out the cooling performance of their Ryzen 5 5600.
What I like about this thermal paste
- Easy to apply and clean off
- It does not contain any hazardous chemicals.
- It is available in multiple variants.
- It features non-curing, non-conductive technology for a safe application process.
What I don’t like about this thermal paste
- The price per gram is competitive but could be discouraging when we consider other, more affordable options on the market with similar performance offerings.
Thermal Grizzly Kryonaut
Thermal Grizzly Kryonaut
$21.99
- Low viscosity for easy application
- Made with zinc oxide and boron nitride for excellent performance
- Non-conductive for safety
- Long-lasting (up to 8 years)
- Premium price
With premium heat reduction and performance, the Thermal Grizzly Kryonaut stands tall above most other thermal pastes, especially for Ryzen CPUs. The thermal compound is made of nano-scale particles, creating an even insulation layer between Ryzen 5 5600 and your cooler.
Using this thermal paste, you can reduce temperatures by up to 30 degrees Celsius, which helps with impressive heat transfer.
Another exciting aspect of this product is its durability. Unlike most other options, you won’t need to replace it anytime soon. It has impressive longevity, which justifies its price.
The product is packaged with a spatula (coupled with the low viscosity) for seamless and even distribution of the thermal compound throughout the Ryzen 5 5600. This will favor first-time users.
What I like about this thermal paste
- Long life span
- Easy spreading
- Extremely high thermal conductivity rating of 12.5 W/mK
- Non-curing, non-conductive technology
What I don’t like about this thermal paste
- I couldn’t place a finger on any downside to using this thermal paste. If you have experience with this product, it is a fantastic opportunity to share your experience in the comment section.
Cooler Master MasterGel Maker
Cooler Master MasterGel Maker
$16.99
- High thermal conductivity
- Non-conductive
- Easy to apply
- Long-lasting
- Made with graphene
The Cooler Master MasterGel Maker is another popular and wonderful thermal paste option for Ryzen 5 and 5600 processor users. It is available in w/m-k with thermal conductivity ratings of 14, 11, 9, and 5 and specific gravity ratings of (g/cm) (25 °C) of 2.6, 2.6, 2.6, and 2.05, respectively.
The color of this product is gray, and all volumes come with a grease cleaner and scraper (except the smallest thermal-rated product)
With a new exclusive flat-nozzle syringe design, you can say goodbye to the messy application of thermal paste because it will help you distribute a flat, precise, and even spread of paste.
It is formulated with the phenomenal Nano-Tech Diamond particle properties that befit gamers who need the best thermal conductivity for high-performance CPUs, GPUs, or even chipsets.
The nanodiamond particles are also extremely lightweight and easy to spread or remove. The aesthetics of this product are also something to talk about.
What I like about this thermal paste
- Enhanced User Experience Design
- High conductivity for improved heat transfer
- Precise and Even
- 11 W/m.k. thermal conductivity rating
What I don’t like about this thermal paste
- Despite the flat-nozzle syringe design, some users have reported that the MasterGel Maker can be difficult to apply, particularly due to its thick consistency.
- Slightly higher cost than the average product on the market right now
Gelid Solutions GC-Extreme
Gelid Solutions GC-Extreme
$24.99
- High thermal conductivity
- Non-conductive
- Easy to apply
- Long-lasting
- Made with nanoparticles
Finally, Gelid Solutions GC-Extreme is not new in the thermal paste market. But it is particularly known for its compatibility with extreme uses since it achieves the best heat conductivity and is easy to apply.
Like most other highly rated thermal pastes, this one is made with nano-diamond particles that provide high thermal conductivity and long-lasting performance.
It comes with the GELID Applicator, which allows you to apply the paste easily. The operating temperature is also decent, working from -45 to +180 degrees Celsius. In addition, the GC-Extreme has a Thermal Conductivity of 8.5W/mK and a density of 3.73g/cm3.
What I like about this thermal paste
- Created for extreme use
- You can max out thermal conductivity at 8.5W/mk
- Easy and safe application
- Operates between -45 degrees and +180 degrees Celsius
What I don’t like about this thermal paste
- It is not the easiest to remove. I experienced a laborious cleaning process while upgrading the system to remove the thermal paste. However, the thermal performance is top-notch.
How to pick the best thermal paste for your Ryzen 5 5600X
It’s simple.
The first and apparent key factor you want to remember when choosing any of the above highly rated thermal pastes for Ryzen 5 5600X is whether you want liquid metal thermal compounds or non-conductive paste. While liquid metal thermal compounds can be pricey, they dissipate heat faster than non-conductive pastes.
Another salient factor to remember as you make your buying decision is low thermal impedance. Go for the thermal compound that quickly and efficiently dissipates heat from the CPU, and its thermal impedance level will say so much about this feature.
Longevity and durability are also worth considering before you shell out cash for a new thermal paste. But above all, do not forget that your budget will also factor into your choice.
The Bottom Line
While a few thermal paste products stand out above others and are ideal for Ryzen 5 5600X, I will still recommend that you go for whatever fits your budget and personal “taste” (color, brand name, etc.)
This is because the only temperature performance difference you will notice between these top-rated thermal pastes (if you do notice any) is between 1 and 3 degrees Celsius.
Still, some are more ideal for some gaming needs than others. For example, Thermal Grizzly’s Kryonaut is the thermal paste I recommend for overclockers and enthusiasts.
On the other hand, if you’re an average user, it hardly matters compared to the price differences.
