Description

Visit the Store The Kryonaut thermal paste offers excellent thermal conductivity and remains stable even at high temperatures without curing – ideal for extreme cooling demands. Available in four sizes: 1g | 1.5ml | 3ml | 10ml The Kryonaut thermal paste has been optimized for "Kryonauts" and demanding cooling applications, delivering impressive durability and excellent heat dissipation. Thanks to nano-aluminum and zinc oxide, Kryonaut compensates for surface irregularities and ensures optimal contact. Kryonaut 1g comes with a spatula to simplify the application of the thermal paste. My thermal paste is difficult to spread or comes off the surface. What can I do? The surface should be thoroughly cleaned and be free of grease before use. The thermal paste should be at least at room temperature when applied. It is important to spread the thermal paste very slowly during application. How long is Thermal Grizzly thermal paste usable after opening? With proper storage and packaging, the thermal paste can be used for at least 3 years without issues, and in many cases, significantly longer. Why can't I find the thermal conductivity value on the packaging? The typically theoretical thermal conductivity values vary greatly depending on the application, as important factors such as contact pressure, temperature, or surface cannot be uniformly accounted for. Should I store the thermal paste in its original packaging after use? Thermal Grizzly thermal paste packaging is specially coated on the inside to protect the syringe and its contents from UV radiation and other environmental influences. We recommend storing it in the original packaging. The surface should be thoroughly cleaned and free of grease before use. We recommend using TG Remove or TG Cleaning Wipes for cleaning. The thermal paste should be at least at room temperature when applied. When applying, it is important to spread the thermal paste very slowly. For a typical Intel or AMD CPU, a single spreading motion should take about 3 seconds. The slower the movement, the easier it is to spread the paste evenly.

    • Extreme Performance Thermal Paste That Delivers Noticeable Results
Size: 1 Gram
I recently used Thermal Grizzly Kryonaut (1 Gram) for my CPU repaste, and I’m impressed with the results. This thermal paste is clearly engineered for high-performance applications and demanding systems like gaming PCs, overclocked setups, and even consoles such as PS4, PS5, and Xbox. Application was smooth and straightforward—the paste spreads evenly and has a nice consistency, not too thick or runny. After applying it to my CPU, I noticed a significant temperature drop under load, which gave me peace of mind, especially since I push my system with heavy gaming and mining. ✅ Pros: Extremely high-performance thermal conductivity Easy to apply with even spread Noticeable temperature reduction on CPU & GPU Ideal for overclockers and high-demand builds ❌ Cons: A bit pricey for the small 1g tube Best results only when applied carefully 💡 Tips: Clean off old paste thoroughly with isopropyl alcohol before applying. A pea-sized drop in the center usually works best for CPUs. For GPUs or larger dies, spread a thin, even layer for full coverage. Keep an extra tube on hand if you frequently build or repaste. Bottom Line: If you’re serious about system cooling and stability, Thermal Grizzly Kryonaut is worth every penny. It’s one of the best thermal pastes I’ve used, and I’ll definitely stick with it for future repasting jobs. ... show more

    • Excellent Product. 1 year strong and still like 1st application
Size: 5,55 Gramm / 1,5 ml
I bought this paste for 3 different devices: an Asus G20CB desktop, an HP Pavilion desktop, and a 2021 Asus G14 laptop. After verifying that the paste was authentic, application was pretty straightforward and easy since it came with 2 different nib/spatula tips for the syringe of pate. I basically run stock after removing the bloat, no overclocks or anything, but I still wanted to repaste due to improvements to temps. Because of that the 2 desktops didn't see much difference, 3–6-degree Celsius give or take for the CPUs and GPUs. And even now, it is still holding the same temps as it did underload as it did when I 1st repasted it. My G14 however did see a sizeable improvement from what it originally had; CPU saw a 13 degree drop and GPU saw a 5-degree drop. I can't really say if it was because the factory liquid metal application was botched or just old, but this paste does well enough to keep the CPU from going past 85 degrees since before repasting my highs would sometimes reach 100 degrees and prevents my fans from turning into jet engines. It did last a good 13 months before temps are starting to slowly climb, so I will need to repaste soon. Will probably try Hyronaught this time since others reportedly say that it is better for laptop use due to higher idle and heavy load temps. Overall, it is an excellent product (if authentic, BEWARE OF FAKES). Yes, it is expensive, but the performance results do speak for itself and the reputation that it gained as a go-to by known overclockers is warranted; but it is ultimately up to you how much you value that improvement and if it is worth the price. For me however, despite not being an overclocker, it was worth every penny since lowering those operation and idle temps is just another way to have my last longer. ... show more

    • Best cheap replacement.
Size: 1 Gram
Great thermal paste, plenty to spare if I need more, and did a great job cooling my PC better. Recommend to anyone who needs a quick and cheap fix to their cpu paste. Installing was very easy and the adhesive sticked well. Recommend to absolutely everyone.

    • Good, but not for every use case - a myth about thermal paste
Size: 1 Gram
Let me preface this whole things by saying that Kryonaut is a really good thermal paste for cpus. It helped decrease my tdie temps by a massive margin (over 5 degrees), and thermal conductivity is impressive while being easy to apply. But putting it on gpus... let's just say I bought this before I had actually done proper research because I had heard so much good about it. *sigh* time for the long boring essay... **TL;DR: pump out is bad for long term thermals and this has especially bad pump out. anything with IHS (cpu) gooood, anything without (delidded cpu, gpu, socs, laptops, etc.) baaad A lot of people tend to think thermal paste is either all the same or only look at conductivity. However, with this paste, I figured out the hard way that thermal paste is way more than heat dissapation. Pump out occurs through many repeated cycles of rapid heating and cooling and causes the thermal paste to dissipate outwards and leave little to no paste on the core, usually through a long time period (3-10 years, depending on quality). This is more prominent on gpus as those have no ihs and tend to heat and cool more violently than cpus do. Thicker, more viscous thermal pastes are less prone to this. Unfortunately, this thermal paste in particular has especially terrible pump out because it's thin and watery. It worked WONDERS on my cpu as I mentioned earlier. An already great temp of 65c or so fell to 55-60 while gaming in ambient 22-27c. No pump out issues and it stayed like this until I changed coolers. On my gpu, it worked well - at first. 55c with 8 degree delta between hot spot and core. It almost instantly (within a month or two) started to have bad deltas (meaning pump out was causing die to heat up in certain spots more than others). Delta was around 8c, then slowly rose to 15c+ (worst I saw was 20c) and core temp also rose from 55c to 60c to 65c. When I replaced it with a thicker, much more resiliant thermal paste (thermalright tfx), it has been consistently good at ~57-61c and 10-12c delta for the past 3 months. All in all, it's a great paste that has amazing thermal conductivity (although that standard is nonexistent). your cpu temps will drop if you are replacing old or otherwise low quality thermal paste. However, it's a lot of money for the amount of paste you get, and being the way it is, it is not designed for direct die contact, so bear that in mind. Be aware that different thermal pastes have different use cases, and this is not for gpus. If you want that from thermal grizzly, there is hydronaut and liquid metal (though I have not used either). I personally just recommend arctic mx5 and tfx and maybe noctua nt-h2. ... show more
