Best Thermal Paste For Ryzen 5 5600X 

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.

Top 5 Thermal Paste for Ryzen 5 5600 X

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.

1. Arctic MX-6
2. Thermal Grizzly Kryonaut
3. Cooler Master MasterGel Maker
4. Gelid Solutions GC-Extreme

Here’s why they are the best:

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.

Thermal Grizzly Kryonaut

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.

Cooler Master MasterGel Maker

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.

Gelid Solutions GC-Extreme

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.

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.
