Better and cheaper than LSD
After a quick taste I could communicate with walls. Also works well as thermal paste. Dropped temps by 10C. Bit sticky and gooey but I think most of y'all have more braincells than I do, so you'll figure out how to use it.

Great thermal paste
Had been having overheating issues with my Amd 3950x for a while. Had read great reviews about Thermal Grizzly Duronaut. Was pretty tricky to apply but was worth the effort. Now my 3950x is nice and cool, no more throttling. Abit more expensive than other pastes, but worth it.

First Impressions = Very Good
As someone that has used Kryonaut for more years than I can actually remember, I wanted to try Duronaut out when I became aware of its existence. I did email Thermal Grizzly prior to buying to make sure that it was at least as effective as Kryonaut was (no point going backwards!) & was told that it is basically an improved version of Kryonaut but was given a different name as some people may prefer the consistency etc of Kryonaut. Performance-wise on an overclocked Intel i9 13900K cooled by an Arctic Liquid Freezer 3 360mm cooler (with Noctua NF-F12 Chromax fans & anti-vibration gaskets instead of supplied fans), the peak temperature was the same as Kryonaut after an hour of Cinebench multicore runs to ‘bed in’ the paste. There was no thermal throttling even being overclocked nor increase in fan speed than with Kryonaut. Application is a little easier as Duronaut is slightly thinner in consistency compared to the Kryonaut I have left to hand. Was easy to spread across the IHS with the supplied spatula. Value for money is also better than Kryonaut as it is a little cheaper gram for gram. The only thing I would like to see different is for the syringe to have what paste is inside it labelled on the outside as the syringe I got only had the Thermal Grizzly branding. This isn’t really a problem as I keep the syringe & applicators together in the outer packaging, but if you just put the tube in a drawer with other TG pastes, it could be easy to mix up which is which. Cannot give a long term use review as not had it for that long but for now it is performing as I would expect a TG product to. I wouldn’t use it for repasting GPU cores personally & the guy at Thermal Grizzly I communicated with via email also said the same. For GPU cores there are better products such as the sheet style TIMs. Would I rebuy Duronaut? Only time will tell but I do have high hopes for it going on what others I trust in the industry tell me.

Best thermal paste I've used.
This stuff is a game changer for low temps. After applying the paste I ran y-cruncher for 30 minutes with an i7 14700k at stock and my temperature never exceeded 74c. During Space Marine 2 which is CPU heavy my temps were in the 40's. Now on to the applying of the paste. I think it's a bit unfair that people mark this product down because it's more difficult to apply, Yes it is more difficult to apply and I could tell this straight away but the manufacturer provides a video of how to do it correctly. I followed the video to the letter and had absolutely no issues applying the paste although it did take a bit more time and patience. I wouldn't hesitate to buy this product again.

Perfect for the perfect amount of thermal paste
After running out of my previous Thermal paste (also Thermal Grizzly but a lot smaller) I found this at a really good price, so thought I'd go for the bigger tube this time. As always really good thermal paste from Thermal grizzly, does what it's supposed to do

Fantastic with patience
It's an absolute PITA to apply but to be fair Thermal Grizzly aren't secretive about this and do have videos on their site. Once applied though, this stuff is fantastic. Used it to repaste my GPU after a paste blow out on a 4080 and my temps dropped 10 degrees

This is a waste of money and my temps went up by a shameful amount
I am fairly certain this is a scam. My idle CPU temps when using my £5 arctic paste was 50 degrees. Using Grizzly Duronaut It gets as high as 70 degrees. Considering this is sold for overclocking you could actually destroy your pc using this. I would normally see 70+ degrees while doing something CPU intensive like gaming or running something like folding at home. Having a 70 degrees temp while doing nothing is just crazy for a £20 pound tube of thermal paste. They appear to be selling poor quality paste at in insane price with the added risk of you using it and destroying your pc. I reported this to amazon and gave the scripted sorry it's a third party seller there is nothing we can do even though they are helping this scam operate. I am disabled and don't want the pain of going to a post office just to send this scam product back for a refund. Everyone wins here except the customer. Amazon and the seller make money while you risk destroying something worth over a grand and have the added luxury of having to buy more thermal paste and open your computer and respate with a real thermal paste. The ASA should know about these kinds of practices.

Excellent performance, noticeable drop in temps!
I used the Thermal Grizzly Conductonaut (2g) on my CPU, and even though I applied a bit too much the first time, it still delivered fantastic results. After cleaning and reapplying carefully, I noticed a clear improvement in my temperatures — significantly lower under load compared to standard pastes. It spreads easily, and you only need a tiny amount to get full coverage. The consistency feels premium, and you can tell it’s designed for enthusiasts looking to get the most out of their cooling setup. If you’re confident applying liquid metal or high-performance compounds, this is an incredible upgrade. Just be careful with the amount. A little goes a long way. Overall, brilliant thermal paste that really makes a difference!

La meilleure que j'ai jamais essayé!
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.

Vraiment exceptionnel
J’ai utilisé la Thermal Grizzly (notamment la version Kryonaut) pour le remplacement de pâte thermique sur mon PC, et honnêtement on comprend vite pourquoi cette marque est autant recommandée dans le milieu du hardware. Dès l’application, on sent que le produit est sérieux. La texture est assez facile à étaler, pas trop liquide ni trop épaisse, ce qui permet une répartition homogène sur le processeur sans difficulté particulière. On n’a pas besoin d’en mettre beaucoup, une petite quantité suffit largement. Le vrai point fort, c’est évidemment les températures. Après remplacement, j’ai constaté une baisse visible par rapport à une pâte thermique standard. En charge (jeux, streaming, tâches lourdes), les températures sont plus stables et surtout mieux maîtrisées, ce qui permet au CPU de maintenir ses performances plus longtemps sans monter inutilement en chauffe. Sur un usage type gaming ou rendu, la différence peut ne pas sembler “spectaculaire” au premier abord, mais sur la durée et en charge prolongée, la stabilité thermique est clairement meilleure. C’est là que le produit prend tout son sens. Autre point important : la qualité globale et la fiabilité dans le temps. La pâte reste stable, ne sèche pas rapidement et garde de bonnes performances sur plusieurs mois d’utilisation, ce qui est rassurant pour un montage PC sérieux. Il faut aussi noter que c’est une pâte thermique orientée performance, donc elle est surtout intéressante pour les utilisateurs exigeants : gaming intensif, overclocking, streaming, ou machines haut de gamme comme un i9 ou un gros GPU. Points forts : ✔ Excellentes performances thermiques ✔ Baisse des températures CPU/GPU ✔ Facile à appliquer ✔ Bonne stabilité dans le temps ✔ Idéal PC gaming / haut de gamme ✔ Marque reconnue dans le monde du hardware Points à noter : ➖ Prix plus élevé que les pâtes thermiques classiques ➖ Gain surtout visible sur configs exigeantes Verdict : Très clairement une des meilleures pâtes thermiques du marché. Ce n’est pas un “gadget”, mais un vrai upgrade pour optimiser les températures et la stabilité d’un PC performant.

Polecam
Zdaje efekt sprawdzony na i9-12900 i jestem mega zadowolony. Najważniejsze: ciężko się nakłada go. Są sposoby, aby na chwilę wsadzić do ciepłej wody, wtedy ponoć łatwiej się go rozprowadza.

Buen producto
Excelente producto cumple con su propósito crompre una laptop y las temperaturas andaban en cpu entre 95° y 100° en la gpu andaban entre 85° y 90° me ayudó a bajar las temperaturas 10° Ojo la pasta que traía mi lap estaba seca como piedra por eso no disipaba nada así que este producto me sirvió, pero no creo que sirva para bajar más la temperatura en casos donde la pasta todavía no esté tan seca.
