Thermal Grizzly Hydronaut
Specially developed for large-surface heat transfer mediums
Optimized for medium and large heat sinks, Hydronaut delivers consistent peak performance. Perfect for water cooling and large systems requiring maximum heat dissipation.
Available in four sizes: 1g | 1.5ml | 3ml | 10ml
Flexible application without curing
The silicone-free structure of Hydronaut thermal paste ensures flexibility and easy application without curing. This keeps your cooling system reliably cool and the thermal paste durable and efficient over time.
Application Tools
Hydronaut 1.5ml includes an applicator to make applying the thermal paste easier.
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.

It dispenses easily and spreads well with that weird rubber spatula tip. I've used this brand of grease on 3 CPUs now and am very impressed with its ability to keep my CPUs cool.

... someone would pay this much for cpu thermal paste. Now I understand! This stuff took a troubled GPU with a 100° hot spot and made it hum again. Get it!

Good thermal paste. It is easy to apply and rates very well everywhere I see reviews on thermal paste.

Been using strictly thermal grizzly paste for years and hydronaut is my go to.The spreader tip works amazingly. The syringe works very well and doesn’t rocket out paste. Cleans up easy with a little isopropyl . I also noticed it does last longer than some other brands so you won’t have to reapply as often.Overall I highly recommend, it’s great bang for your buck performance and quality wise.

previously i had issues with re-pasting laptops as even high performance ones pump out quickly, however with this paste it actually lasts and can stand laptops high temps, really recommended for laptops

I did a lot of research into thermal paste. This was what I settled on for my AIO. Would it have made a difference? I don't know for sure, but I know I've been happy with the performance and use of this product.Is it one of the best pastes? Yes.Is it one of the longer lasting pastes? Yes, from what I can tell.Was it easy to use? Yes. Spread was easy, but you can easily use a line and spread it with heat sink pressure as well. It's thick enough that it can stick if you want it to and can coat a device easily.Is it the absoulte best? Specs say no. but...Is it a great value? Yes. The more expensive stuff has ratings that are barely better than this at 3-5 times the price. At best, that might find you an extra 1-2C when doing some pretty extreme things.I'm a power user, but I'm practical. This stuff is great for my PC, and one day I may repaste my old laptop with this as well. Given I've leaned into undervolting vs Overclocking, this gives me all the performance I need.

アプライドで組んで貰ったＰＣですが、突然電源が落ちる、再起動することが多く、CPUの温度を測ると９０℃～１１５℃近くと、かなり温度が高かったのでこのグリスを購入して塗ったら４０℃～５４℃程度に安定した。写真UPしますけど、アプライドは、液体の様なグリス？を１滴垂らしたような跡（写真参照）からほとんどグリス塗っていない状態で販売したようで、グリスをしっかり塗るとこんなにも違うのかという体験が出来ました。８年もこんな状態で高温なCPUで壊れずに使えてた。

It's 100% real but I gave it 4 stars because of the tube size first I read all the reviews I got scared that I thought it will be fake it you use it in correct way it will work and I used it in my PS4 now the temp is down and it's not giving any messages like. Your PS4 is too hot
