Its precise syringe application and versatile compatibility make it ideal for CPUs, GPUs, and gaming consoles like PS4, PS5, and Xbox. With a non-hardening, silicone-free formula, it ensures long-lasting thermal stability, perfect for both air and water cooling systems. ## Description 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 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. Hydronaut 3ml comes with two applicators for effortless thermal paste application. My thermal paste is difficult to spread or comes off the surface. What can I do? The surface should be thoroughly cleaned and be free of grease before use. The thermal paste should be at least at room temperature when applied. It is important to spread the thermal paste very slowly during application. How long is Thermal Grizzly thermal paste usable after opening? With proper storage and packaging, the thermal paste can be used for at least 3 years without issues, and in many cases, significantly longer. Why can't I find the thermal conductivity value on the packaging? The typically theoretical thermal conductivity values vary greatly depending on the application, as important factors such as contact pressure, temperature, or surface cannot be uniformly accounted for. Should I store the thermal paste in its original packaging after use? Thermal Grizzly thermal paste packaging is specially coated on the inside to protect the syringe and its contents from UV radiation and other environmental influences. We recommend storing it in the original packaging. 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. 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’ve used Thermal Grizzley products and they perform well. CPU temps are always at 29 C and lower at idle. Heavy gaming temps run at 60 to 70 C. CPU is an Intel 13900ks. Would recommend this thermal paste. ### ⭐⭐⭐⭐⭐ Great overall *by on Reviewed in the United States May 5, 2026* Pretty straight forward product, the adapters make it really easy to get an easy spread, and for the price of 2 grams normally, pretty hard to beat for 8g of actual quality. ### ⭐⭐⭐⭐⭐ 10/10 this product is great! *by on Reviewed in the United States July 5, 2023* I've been using Hydronaut now for quite a while, I bought the big 26 gram tube the first time (unfortunately I lost it so I didn't get to use it all) and this time I bought the medium sized 7.8 gram tube.I used to use Arctic Silver 5 a long time ago and it was always pretty good but it never really lasted too long before it became a solid and then trying to clean it off always made a mess. Hydronaut always remains paste and even though you'd think thats messier its easier to clean because you know it isn't half solid/half paste.Arctic Silver always performed pretty well under heat but Hydronaut just takes it to the next level I don't unfortunately have any tests to show you for temps and things like that but I can at least say it dropped my temps 5c on cpu. Not to mention when I repasted my 3080Ti with it it dropped temps significantly (although thermal paste fromnthe factory is almost always designed for longevity not for performance) ## Frequently Bought Together - Thermal Grizzly - Hydronaut - 7.8 Gram/3 ml - Conductive High Performance Thermal Paste - Ideal for Air and Water Cooling CPU/GPU/PS4/PS5/Xbox - for Large Cooling Surfaces - AMD Ryzen 7 7800X3D 8-Core, 16-Thread Desktop Processor - SAMSUNG 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
