Thermal Grizzly Kryonaut Thermal Grease Paste provides good cooling performance and limits your CPU against overclocking or overheating, it is a better grease-based compound and able to provide maximum heat transfer between the CPU and the cooler. It is aimed at overclockers, which is a big plus. The viscosity of the product depends on the temperature at which it has been maintained, so for best results we recommend that you put the tube in a ziplock bag and immerse it in lukewarm water for a few minutes before applying it on the desired surface.

The application will run smoothly if you follow the aforementioned method. The 1 gram tube comes with a thermal application tool which is very useful if you are trying to apply it in an even coating. It is a durable paste and perfect for replacing your grainy, dried compound.

The Thermal Grizzly Kryonaut is one of the best thermal pastes / compounds currently available on the market for your processor. This ultimate compound provides excellent cooling performance and prevents the CPU / GPU from overheating or even overclocking. It is the most thermally conductive compound at 12.5 W / mK, so you don’t have to worry about the conduction of electricity.

Overall, in terms of performance, this thermal compound doesn’t make any compromises. It is ideal for users who want the best of the best and ultra-high performance. It also has one of the best and high thermal conductivity of all non-conductive thermal pastes.

The Arctic MX-4 is an award winning product. Coming from one of the largest manufacturers of thermal grease, it is a versatile product in its application, which gives excellent results and is offered at a competitive and practical price. The metal-free compound is perfect for VGA and CPU applications and is user-friendly. Arctic says their product performs better than liquid metal pastes, but with a conductivity of 8.5 W / mk, it hardly does.

The MX-4 is very easy to use even for beginners; it is not electrically conductive because it is not composed of metallic particles. This thermal paste has a high level of durability because it is constructed with a fine particle of metallic silver. It provides the conductivity rate of 8.5W / mK as it is a carbon based compound which gives you superconductivity. It is also compatible with nitrogen, air coolers as well as liquids.

It doesn’t have any kind of electrical components. Therefore, you don’t have to worry about it conducting electricity and shorting or damaging the processor while it is being applied. However, it is best to clean it anyway after application.

Ultimately, with the thermal conductivity of 8.5 W / mK and inexpensive for 4 grams, it’s worth considering. With a thermal conductivity of 8.5 W / mK and a lifespan of 8 years once installed, you can almost completely forget about it and move on. In fact, there’s a good chance you’ll need to replace your processor before you need to replace it.

Noctua is one of the best coolers that make systems very cold under high performance and use; it also provides a secure thermal link between the heat sink contact base and the CPU. It is the hybrid thermal compound that offers a high level of cooling without any electrical conduction. It offers faster performance and requires no break-in time.

It is perfect for computer enthusiasts who like to cross the limits of their CPU or GPU as it keeps the system cooler up to 2 degrees. This thermal paste is ideal for beginners who do not have much experience in performing such delicate tasks. It is comparatively thicker and drier than other similar thermal compounds. In addition, an application of this paste on the CPU or GPU lasts about five years if not longer, and its shelf life is about three years at room temperature. Therefore, not only is it cheap and easy to apply, but it is also considerably durable and effective.

The Noctua NT-H1 performs almost as well as high-end thermal pulp, but at a fraction of the price. If you are looking to save some money on thermal paste and not suffer from performance impact, then the NT-H1 is a great choice. You probably won’t have to replace the paste even after the three-year period suggested by Noctua. In the interest of maintaining top performance, you will probably want to replace the batter eventually. But with the inexpensive nature of the NT-H1, you don’t mind having to.
