Thermal Grizzly from Hamburg is a new German brand dedicated to combating high temperatures and poor heat transfer. The goal is to supply the overclocking community with high-performance thermal products, which remain a weak point. However, the product portfolio can also be used for better and quieter cooling of gaming PCs, workstations, mini-PCs, and many other applications. In addition to higher clock rates, better thermal products enable quieter cooling and a longer lifespan for the components being cooled.
The thermal paste named Hydronaut, as its name suggests, is particularly suitable for water cooling systems, but it also performs well between a CPU and an air cooler. With its low density and silicone-free carrier structure, it is especially effective in achieving a thin layer and thus low temperatures in large-area applications. Unlike many competing products, Hydronaut thermal paste does not harden and remains flexible.
The Hydronaut thermal paste comes in a 10 ml syringe with three applicators included. With these applicators, an area of 27 x 27 mm can be covered with a drop of paste about 3 mm in size, making the syringe sufficient for approximately 30 applications—this, of course, depends on individual usage and skill.
