High-conductivity liquid metal paste

Thermal Grizzly Conductonaut TG-C-005-R is a liquid metal thermal compound rated at 73 W/mK. The 5.0 g syringe uses a eutectic alloy of tin, gallium and indium for maximum heat transfer between a CPU or GPU die and a nickel-plated copper cold plate.

Experienced builders seeking peak cooling

This paste suits enthusiasts who are comfortable handling electrically conductive liquid metal and who can ensure it will not contact aluminium surfaces. Builders who prefer a non-conductive ceramic or silicone grease, or who need a compound safe for bare aluminium heat spreaders, should choose a different product.

Synthetic needle enables precise dosing

The bundled plastic needle lets you place a thin, controlled line of the low-viscosity compound directly on the die. This reduces the risk of overflow onto the substrate or socket area, which is critical because the material conducts electricity and can cause short circuits if it bridges pins.

Questions about this item

What surface material should the CPU heat-spreader have for the Conductonaut 5.0 g paste to remain stable?

Thermal Grizzly recommends a nickel-plated copper heat-spreader for best long-term stability with this liquid metal compound.

Will the Conductonaut 5.0 g paste damage an aluminium heatsink base if I keep my current cooler?

Liquid metal alloys can react with bare aluminium, so the Conductonaut should only contact nickel-plated copper or similar compatible surfaces.

How can I confirm the Conductonaut 5.0 g paste is performing correctly after installation?

Monitor CPU core temperatures under load; they should drop noticeably compared with conventional paste and stay within the 10 to 140 °C operating window.
