Product Identity

The ARCTIC MX-2 thermal compound comes in a 30g syringe for CPU and GPU applications. Its carbon micro-particle formula delivers 5.6 W/mK thermal conductivity. The paste is metal-free and non-electrically conductive, removing short-circuit risk during installation. It suits builders who want reliable heat transfer without liquid-metal hazards.

Thermals, Noise and Power Draw

The 5.6 W/mK conductivity rating measures steady-state heat flow between die and cooler. The 850 poise viscosity keeps the compound in place without pumping out over time. Volume resistivity of 1.22 x 1012 O-cm confirms electrical isolation under normal voltage. Density of 3.96 g/cm³ gives a consistent spread that resists drying.

Sustained Load Behaviour

Carbon particles do not degrade or separate under prolonged thermal cycling like some metal or silicon pastes. The non-curing compound maintains its viscosity and contact integrity through repeated heat-soak periods. Long-term stability means re-application intervals can be extended. Users needing higher conductivity for extreme overclocking should consider alternative formulations.

Questions about this item

How do I apply the MX-2 thermal paste correctly and what common step should I avoid?

Apply a small pea-sized dot or thin line onto the centre of the CPU heat spreader, then mount the cooler straight down; do not spread the paste manually with a card or finger because that traps air bubbles and reduces the 5.6 W/mK conductivity.

Will the MX-2 compound need replacement or maintenance after installation?

The carbon micro-particle formula is non-drying and rated for high durability, so it does not require periodic re-application unlike metal or silicon-based compounds that can pump out or degrade over time.

What thermal limit appears first when the MX-2 is under sustained heavy load?

With 5.6 W/mK conductivity, 850 poise viscosity and 3.96 g/cm³ density, the paste itself remains stable; the practical limit is the cooler's ability to move heat away from the CPU or GPU die.
