Thermal Grizzly Duronaut - 6 Gram - Enhanced Durability & High Performance Thermal Paste - for Maximum Thermal Conductivity While Overclocking CPU/GPU/PS4/PS5/Xbox

The product is great. It's extremely thick and was more difficult to apply than cheaper brands, but I used the included applicators to spread it on and it is working great. I have a great connection between my cooler and the CPU and it is keeping my ryzen 9 5950x nice and cool. I highly recommend this product for high end processors.

Love this stuff. Value for money. Great quality. Lasts a long time.

Thermal Grizzly Duronaut was easy to apply on my Ryzen 9 9900X using the included spatula. I spread a thin, even layer—not transparent, but controlled—and it behaved exactly as expected. During installation I had a moment where the AIO block made contact and lifted straight off due to a mounting alignment issue, but the paste held up perfectly and didn’t affect performance at all. Across all of my testing, including sustained AVX workloads, the CPU stayed cool and stable and held around 62 °C. In real‑world workloads like photo & video upscaling, batch video encodes and large software builds, I typically see temperatures in the mid to high 60s and occasional spikes into the 70s, which is completely normal for the 9900X and still well within comfortable thermal limits I've also observed idle temperatures as low as 35c, but they usually sit between 36-39c. Duronaut clearly provides excellent thermal transfer and consistency under both synthetic and real‑world workloads.

I have bought thermal grizzly's PTM7950 (PhaseSheet I think they call it) in the past for repasting GPUs. While I did like the product, I decided to give Duronaut a go mainly because it was a fair bit cheaper considering the amount of coverage you get. That and my tube of MX4 from gods knows how long ago was starting to separate and I needed a standby thermal paste. The Duronaut is far thicker than standard thermal paste that most people are used to. Really quite thick; I would estimate kind of peanut butter thickness (though I hardly know since I don't like peanuts). There's a bit of a learning curve to spreading the thermal compound over a die. Thermal grizzly have a video on youtube on how to spread it that had some good advice in that regard. If you try to spread it too fast it tends to detach from the die or create patchy coverage. You kind of have to apply what looks like a lot more thermal paste than necessary to spread it out. I found the special spatula they give you helps a lot in controlling the spreading, and you have to go pretty slow. I used this thermal paste to repaste my GPU--which had concerning hotspot temperatures--and a friend's laptop which sorely needed repasting. I've been running the repaste on my GPU for a couple of weeks now and it's holding up great with no signs of rapid deterioration or temps increasing.

I’ve used several thermal pastes over the years, and the Thermal Grizzly Duronaut definitely performs at the top of the pack. After applying it to my i9-based gaming PC, I noticed CPU temps dropped by about 2–3 °C under heavy load compared to my previous paste (MX-6). It’s non-conductive, spreads cleanly once it warms up, and seems to hold temps steady even after long gaming or rendering sessions. The 6-gram tube gives you plenty of paste for multiple builds, which makes it a good long-term buy. My only complaint is that it’s a little thicker than expected — not the easiest to spread evenly unless you warm it slightly or use a spreader. Also, while the performance is excellent, the difference might be small if you’re not pushing your system hard. Overall, this is a great choice for enthusiasts or anyone who wants high-end, reliable thermal performance. It’s a bit pricey, but you really do get the quality and consistency Thermal Grizzly is known for.

This stuff work and outperforms other thermal pastes. The amount you get is worth the price because the 6g is basically 3.34 per gram and there is a lot of it to last me for the next 4 yrs. The claim that it drops cpu temps is no smoke but all reality. I use air cooling and was getting 28C to 30C per core and around 50-55C total temp on my Ryzen 9 7900x with Corsair TM30 Performance Thermal Paste. With this stuff.....This stuff I am now getting 22C - 24C per core and getting 44-50C. This stuff blows my mind on how good it is and I didn't change my heatsink which is a Thermalright Peerless Assassin 120 SE CPU Cooler, 6 Heat Pipes AGHP Technology, Dual 120mm PWM Fans. Same cooler and I get a 6 degree drop and when I game it barely breaks maybe 55C total temp and 28-34C per core. So yeah it's 20 bucks but its 20 bucks that worth spending.

Very quick shipping.

It works. It's messy. (like every other thermal paste) I'm no thermo-engineer but I can't say it works any better - or worse - than the others.

Depuis plus de 25 ans que je monte des PC et que je les entretiens, j'ai testé beaucoup de pâtes thermiques: la MX-4, MX-5, la Prolimatech PK-3, qu'on ne trouve plus (qui est excellente), la Arctic 5, la Noctua, la Kryonaut du même fabricant également. Celle-ci est au dessus. J'ai changé la pâte thermique d'un vieux PC portable gamer Asus de 2015, lequel est équipé d'un i7-4710HQ et d'une GTX 860M, et les températures sont tombées de plus de 10°C en moyenne. L'ancienne pâte thermique était sèche, mais maintenant, en jeu, il n'atteint plus la limite de température du CPU, et donc, plus de throttling en charge. La fréquence reste aux environs de 3280Mhz, et la carte graphique peut elle aussi tourner plus rapidement, bref, cette pâte lui permet de donner son réel potentiel sans surchauffer. Le petit truc, c'est qu'elle est bien plus difficile à appliquer que les autres, car elle n'est pas du tout liquide et souple comme les autres pâtes. Elle est très visqueuse, et ne s'étale qu'avec une spatule sur laquelle il faut appuyer. Il est donc nécessaire de chauffer avec un petit sèche cheveux par exemple, pour que la pâte gagne en souplesse. Une fois cela fait, c'est plus facile, et avec l'habitude, on y arrive très bien. Les performances sont là, je vais donc la mettre aussi sur mon portable Lenovo qui en profitera bien avec les 8 coeurs du Ryzen Pro! En conclusion, si vous avez l'habitude de ce genre d'opération, c'est la pâte thermique que je recommande. Si vous êtes débutant, regardez des tutos sur le net, il y en a des dizaines, faites plusieurs essais, prenez votre temps, c'est faisable avec un peu de pratique, et cela vaut le coup, c'est un très bon produit! Je pense que nous sommes là en présence de la nouvelle référence en terme de pâte thermique "classique" pour les puces électroniques.

Una pasta de alto rendimiento que no se seca "Lo que más me ha gustado de la Duronaut es su estabilidad a largo plazo. En mis pruebas, las temperaturas son 1-2 grados mejores que con otras marcas premium, pero la verdadera ventaja es que está diseñada para no endurecerse. Es perfecta tanto para procesadores como para GPUs.

Not sure what this magical paste is, but either I had a poor seal/mount on my CPU prior to using this thermal paste, but after switching I have seen a 5 Celsius Temp drop! (No Joke). I was using the Kryonaut, and figured I would try this paste as I had to service my loop. To actual apply this evenly, I did have to heat it a little bit, I did find it a little harder to spread than the Kryonaut, However, Thermal Grizzly did include a new style spreading tool. to assist in the application. Which worked well, and even better after it was warmed up. Recommend!

La migliore pasta termoconduttiva sul mercato. Nella confezione ci sono tutti gli strumenti e le istruzioni per applicarla. Unica nota negativa, l'applicazione risulta alquanto difficoltosa e necessita qualche tentativo in più della media per arrivare ad una applicazione omogenea sulla superficie della CPU.
