Hydronaut 3 ml thermal grease

Thermal Grizzly Hydronaut TG-H-030-R is a 3 ml silicone-free thermal compound rated at 11.8 W/mk conductivity. It targets enthusiasts building water-cooled or large-air systems who need reliable heat transfer without curing time. The paste operates from -200 °C to +350 °C and carries no electrical conductivity risk.

Overclockers and custom-loop builders

Suited for overclocking on medium-to-large coolers where a non-curing, aluminium-safe paste simplifies maintenance. Buyers who want a tiny syringe for a single laptop repaste or who prefer a metal-based liquid-metal alternative should look at something else.

Simple syringe application

The 3 ml syringe dispenses a light, flexible grease that spreads easily under pressure from a water block or heatsink. No curing means immediate mounting and no pump-out concerns. The only common error is applying too much on small dies, which can squeeze onto surrounding components.

Questions about this item

Do I need a separate applicator or spreader tool to apply this 3ml Hydronaut paste?

The 3ml syringe design allows direct application onto the CPU heat spreader; no extra tool is required but a plastic card can help spread it evenly.

Will this silicone-free compound with 11.8 W/mk conductivity work safely on my older aluminium heatsink?

Yes, the manufacturer confirms Hydronaut is applicable with aluminium and contains no electrically conductive particles, so it poses no short-circuit risk.

After mounting the cooler, how can I verify the paste is performing within its -200 °C to +350 °C operating range?

Monitor CPU core temperatures under load; if they remain stable and match expected thermal performance for your cooler, the paste is functioning correctly.
