Thermal Grizzly Duronaut
Extreme Durability & Performance for Your PC
Engineered for maximum cooling performance and long-term stability. Duronaut’s advanced silicone oil, aluminum microparticles, and zinc oxide nanoparticle blend ensures minimal pump-out effect and ultra-low thermal resistance. Includes the new TG Spatula Pro for optimal application.
Effortless Spreading for Optimum Cooling
Specially engineered for simple, precise application, this high-performance paste maintains a thin, uniform layer for exceptional heat transfer. The included spatula helps apply even pressure, minimizing mess and pump-out. Enjoy stable temperatures and extreme durability with minimal effort.
Precision with Premium Tools
Our thermal paste includes an applicator, a spatula, and the new TG Spatula to ensure a smooth, even layer every time. Experience hassle-free application, reduced mess, and optimized heat transfer—perfect for maintaining low temperatures and peak system performance.
Application of Thermal Grizzly Thermal Paste
Apply a small amount of thermal paste to the CPU
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.
Spread the thermal paste
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.

I rarely write product reviews but I wanted to give this paste a shot. I usually use MX-6 as my go to. This stuff is horrible to spread. The spatulas are useless and the paste will just stick. I went slow, I applied pressure, I followed their official video. At the end of the process I just made a really big mess and it was even more annoying to clean up. This is putty not paste. I wiped this stuff off and went back to tried and true. Be warned this stuff is a pain to use. The disadvantages of applying this paste far outweighs the benefits of using it.

My temps are lower. I can stress my cpu and it stay at low temperatures.

It is supposed to easier to apply than kryonaut but I had a lot of difficulty. Other than that it’s fantastic. 7965WX sitting at 41° idle and low 70° under stress test in less than ideal cooling conditions.

It's alright. It says it spreads easier than kryonaut, that's untrue. When spreading it tends to stick to itself and the spatula more than the IHS, preventing smooth coverage. But it works and is functionally similar to Kryonaut in terms of temperature.

The paste is good, very good. Just when I thought my system couldn't be any cooler, this paste from TG made my system 5c cooler on avg, min 32c (originally 36c) and max from Cinebench run is 79c (originally 85c). So that's a win.My only gripe is of the new spatula they included. It's a challenge to apply paste with it. I think they should include a spatula angled the other direction (15 to 20 degrees) where the handle is more angled vertically than have the it parallel or horizontal (near 90 degree). I have rather big hands and trying to apply paste with it made it somewhat difficult to use without touching ram or VRMs on board. A spatula with a slight angle would be immensely better to apply the paste, in my opinion!

Being a big big fan of Kryonaut I was hopeful that its successor would be even better, and performance wise it is so far.Time will only tell if the durability is better.But one point it does fall short is how frustrating it is to spread, it likes to stick to the spreader more than the IHS, it is very frustrating to apply evenly, much more so than any other paste.But performance is good.Used it in a system I had previously pasted with Kryonaut when performing some routine maintenance and under the same stress test it managed to shave a degree or two off the previous record. Margin of error sure, but in multiple tests it was a little bit cooler.Thermal Grizzly is and always will be my go to, so this is an easy recommend even with the frustrations to apply.It does make me wish I could break my score down, cuz performance wise this is a easy 5 out of 5.But user friendliness, it needs another try. The consistency and tendency for it to just not want to stick to the IHS of a CPU makes it frustrating for an experienced user, I can't imagine how someone who is re-applying or applying paste for the first time would handle it.

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!

Duronaut batch I got is just awful it would not spread and acted like dried up kryonaut . I even check the certificate of origin and said it was an original product . I have not had issues with kryonaut and one tube of kryonaut has lasted me 10 computers , this I couldn't get one cpu mounted it just would stick to everything but the cpu.

I will start this off, this is the most difficult to spread paste I've ever tried, including Arctic Silver/Ceramique. When I try to do the small bread method, I literally get Prince Rupert's drop-like beads of thermal paste: it is very hard to spread with a spreader (the packaging does include 2), I've found it better to, if it's not a bare die, to just apply small drops over the area and let the mounting pressure squish the paste out. I suspect the paste being really thicc is for longevity purposes: kryonaut was kind of notorious for drying out in a year or 2, especially in laptops. Performance feels fine, CPU temps on a 5800X was comparable to some of the other pastes I've tried out, only time will tell.My issue with this product is the price, which is $18.9 for a decently-sized tube of this stuff. For me, if I need a thermal interface material that lasts for a long time, either it's because the person I'm giving the device to might not maintain the device as well as I do, or if it's a hard-to-reach component like a water-cooled GPU or a laptop, I'll go for a phase-change material like Thermal Grizzly's own PhaseSheet, Honeywell PTM, or Gelid's HeatPhase. Given a LGA 1700-sized piece of Gelid Heatphase is ~$6, a longevity-oriented paste feels a bit of a "jack of all trades, master of none" when it comes to price and longevity advantages: a phase change material will last longer. Thankfully this paste doesn't give up performance in any way, so I'm willing to forgive it. I do however feel like this thermal paste fits in a weird niche: you need great performance, decent longevity, is willing to buy something expensive but not have the budget to go full-in with phase change material

Ich war bislang, nie wirklich begeistert was die Wärmeleitpaste von thermal grizzly betrifft, bis jetzt! Die Duronaut ist wirklich hervorragend und kühlt meine 5900x gute 5°C kühler unter Volllast als jede andere Paste die ich ausprobiert habe und das waren etliche.Eine absolute Empfehlung meinerseits aber man sollte die Paste vor dem Auftragen um besten im Wasserbad wärmen für eine bessere Verteilung

Für CPU und GPU mit eine der besten Wärmeleitpasten die auch erhältlich ist. Wie bei Igors Lab getestet Alles top. Einfach aufzutragen, Temperaturen sind top. Habe eine rtx 3080 ti damit versorgt und die Temperaturen sind um 20 Grad gesunken. Auch auf meinem 13900k gibt es nichts zu beanstanden.
