  • Silicone-free formula ensures easy application and flexibility
  • Non-electrically conductive for safe use on components
  • 0 g syringe provides ample paste for multiple applications

High-performance thermal compound for water cooling

Thermal Grizzly Hydronaut is a silicone-free thermal paste designed for large-area heat transfer in water cooling systems. It delivers a thermal conductivity of 11.8 W/mk and a thermal resistance of 0.0076 K/W. The 26.0 g syringe provides enough material for multiple applications on CPU and GPU blocks.

Verify cooler mounting pressure and surface area

Ensure your water block or heatsink has a sufficiently large contact surface to benefit from the paste's optimised viscosity for medium and large areas. The compound is not electrically conductive, preventing short circuits if it bridges adjacent components. No curing time is required, so the system can be stressed immediately after assembly.

Large-volume syringe simplifies repeated maintenance

The 26.0 g container supports several reapplications during loop maintenance or hardware upgrades without needing a new purchase. Its silicone-free carrier structure keeps the paste flexible and easy to spread evenly across cold plates. RoHS-compliant manufacturing meets environmental standards for electronic materials.

Questions about this item

Does the 26.0 g syringe include a spreader or must I buy one separately?

The 26.0 g syringe contains only the Hydronaut thermal paste; no spreader or applicator is included, so you will need to provide your own tool.

When should I choose the 26.0 g size over a smaller tube?

Choose the 26.0 g syringe if you maintain multiple systems, run a water-cooling loop with large cold plates, or expect to re-paste several times; a smaller tube suits single, one-off applications.

What does the 11.8 W/mK thermal conductivity mean for my CPU temperatures?

The 11.8 W/mK rating indicates very high heat-transfer capability, so when applied between a CPU and a large water-block it helps keep core temperatures lower under sustained loads.
