5 Best Thermal Paste for Acer Predator Helios 300

Best Thermal Paste for Acer Predator Helios 300

If you own a gaming laptop, you’re probably not a stranger to their heating problems, and the Acer Predator Helios 300 is no exception. One of the reasons your PC faces the problem of overheating is when your stock thermal paste ages, as it can dry out and degrade with age, leading to higher temperatures. Changing the thermal paste is one way to get the best performance from your PC during its lifespan. If you’re on the lookout for the best thermal paste for Acer Predator Helios 300 to replace it, your search ends here. We’ve compiled the list of 5 best thermal pastes for your system.

But first, why is a thermal paste important? A thermal paste is a crucial element of your system’s cooling system. By filling the tiny gaps and imperfections between the CPU/GPU and the heatsink, it ensures optimal heat transfer since its a better thermal conductor than air. It is one of the things to try when nothing else is helping to solve the overheating problem.

List of Best Thermal Paste for Acer Predator Helios 300

Choosing the right thermal paste for your system is an important decision and one you should not take lightly.

1. Thermal Grizzly Kryonaut Extreme

Thermal Grizzly Kryonaut Extreme

Thermal Grizzly Kryonaut is one of the top-recommended thermal pastes by experts and enthusiasts alike. Kryonaut Extreme is an upgraded version of this cult classic. It is designed to maximize the heat transfer between your CPU, GPU, and cooler. With a thermal conductivity of 14.2 W/(m·K), it offers considerable improvement over its predecessor. It can work in an impressive temperature range of -250 °C / +350 °C.

It has no electrical conductivity, which is an important aspect when choosing a thermal paste because thermal pastes with electrical conductivity can short your motherboard. With its improved structure, it also outperforms Kryonaut in most cases, which was already the best in the industry by most standards. Do I need to say anymore?

A 2-gram tube is enough for up to 12 CPUs (given that you don’t waste it). It comes in different variants, like a 2-gram tube or a huge 33-gram tub, that’d last you a long time. If you have other devices, like PS4, Xbox, Threadripper, etc., you can use the latter one with them, as well.


  • Designed for extreme overclocking
  • Formulated to perform even in very low-temperature scenarios
  • High performance
  • Easy application
  • No curing required
  • No electrical conductivity


  • Expensive than other thermal pastes
  • It might be less durable than other pastes

2. Thermal Grizzly Kryonaut

If you can’t get the Thermal Grizzly Kryonaut Extreme, its predecessor – Thermal Grizzly Kryonaut – is still the second best choice you should go for. With slightly less performance than the former, at a thermal conductivity of 12.5W, it still outperforms most thermal pastes on the market. Other than that, it enjoys the same features as the Extreme counterpart but is slightly cheaper than it.


  • Designed for extreme overclocking applications
  • High performance
  • Excellent thermal conductivity
  • No electrical conductivity
  • Cheaper than Kryonaut Extreme
  • Easy application
  • No curing time


  • Still more expensive than most other thermal pastes
  • Just like the Extreme counterpart, it might not be as durable as other pastes

3. Gelid GC Extreme

GELID GC-Extreme 3.5g

This high-performance paste excels in demanding scenarios. With a thermal conductivity of 8.5 W / mk and a density of 3.73 g / cm³, this is a great choice for you, especially if you live in hotter areas. While its performance is lower than the Kryonaut, it works extremely well where room temperatures are usually around 30-35 C. Compared to the Kryonaut, it also doesn’t dry out as easily, so it is more durable.


  • High thermal conductivity
  • Non-electrically conductive
  • Non-curing
  • Affordable
  • Durable


  • Thick consistency, so it can be difficult to apply

4. Cooler Master MasterGel Maker

Cooler Master MasterGel Maker thermal paste

Another top performer, MasterGel Maker, sits at the top of Cooler Master’s thermal paste lineup. It is designed to deliver outstanding thermal transfer for demanding applications like overclocking. With a thermal conductivity of 11 W/mK, it helps pull heat away from your CPU or GPU effectively.

It has a patented flat-nozzle syringe, which makes the application of the paste extremely easy, without any mess.


  • Easy application
  • Great thermal conductivity
  • Great for overclocking


  • Expensive price point

5. Arctic MX-6

Arctic MX-6 thermal paste

A successor of the popular, Arctic MX-4, it offers 20% better performance than its predecessor with lower thermal resistance. It is a popular, reliable, and well-rounded paste that balances performance and ease of application. It’s a safe choice when seeking consistent cooling improvement. You can buy it in different package sizes – 2, 4, and 8 grams – giving you flexibility and making it easy to choose according to your needs.


  • Great value for the price
  • Beginner-friendly with easy application
  • Great thermal conductivity and cooling performance
  • No electrical conductivity
  • Comes in different sizes
  • Requires far less reapplication


  • The wipes included with the package smell bad. Go for any other isopropyl alcohol wipes
  • When stored over long periods, there is potential for separation

Final Words

So, there you go. These are the best choices in the market when it comes to choosing a Thermal Paste for Acer Predator Helios 300. You can go for any of these pastes to solve the overheating problem for your system. As long as you’re not choosing a very cheap thermal paste (stick to one from this list to avoid that possibility), how you apply the paste is more important than the paste you choose. The pea dot method will give you the best results with Kryonaut, while with Arctic MX-6, most users say that spreading a thin layer works best for them. If you are getting the thermal paste changed from a center, make sure that they use a good quality paste and not a cheap one, as it’ll leave you with the overheating problem again in a matter of weeks.
