Thermal Grizzly Kryonaut - 1 Gram - Extremly High Performance Thermal Paste - for Demanding Applicat

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.

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.

Great stuff! Solid temps and does the job!

Great thermal paste. The one gram quantity is the perfect amount for repasting your CPU, a little maybe left depending on your preference at applying thermal paste, but will not be enough for a second CPU. Affter applying the paste and placing the CPU cooler, the components get really connected, which is great for the maximum amount of contact for thermal dissipation, but makes it hard to remove cooler if you wanted to check the spreadmof the paste.

This thermal paste performs well and does its job as expected. Temps improved compared to older paste and it spreads easily during installation. The only downside is the amount included — the tube is very small, so it’s best suited for a single application or quick job. Overall, good quality paste, just not much of it.
