Carbon micro-particle thermal paste 2.0 g

ARCTIC MX-4 2019 Edition is a carbon-based thermal compound supplied in a 2.0 g syringe. It targets PC builders and upgraders who need reliable heat transfer for CPUs, GPUs and other chip packages. The paste is non-electrically conductive and non-capacitive, so accidental spread onto surrounding circuitry will not cause shorts. Its non-curing formula remains stable for at least eight years without drying out.

Practical limits of the 8.5 W/mK conductivity

The material delivers a thermal conductivity of 8.5 W/mK and a viscosity of 870 poise at a density of 2.5 g/cm³. These figures set the practical ceiling for heat flow between a die and a cooler; the paste cannot overcome a cooler's own thermal resistance or a case's airflow limits. Because it contains no metal particles, it avoids the galvanic corrosion and electrical risk that liquid-metal compounds introduce. The non-bleeding characteristic means the compound stays in place under thermal cycling.

Check mounting pressure and surface condition

Before ordering, verify that your cooler's mounting mechanism provides even pressure across the die so the 2.0 g volume can form a thin, uniform layer. Confirm that both the die and cold-plate are clean, flat and free of old compound residue; any gaps or contamination will increase thermal resistance beyond what the 8.5 W/mK rating can compensate for. The syringe volume is sized for several typical desktop applications but may be insufficient for large server dies or multiple GPU repastes.

It is an electrically non-conductive paste that is applied between CPU / GPU and designated coolers to transfer the dissipated heat from the components to the heat sink. Since the ARCTIC MX-4 is a metal-free compound, it eliminates the risks of causing short circuit and in turn adding more protection to your computer. The new formula in the ARCTIC MX-4 features optimal thermal cond

Questions about this item

Is the 2.0 g syringe enough for a single CPU application?

The 2.0 g syringe provides multiple applications for standard CPU sockets, so one tube covers a single installation with plenty left over.

What does the 8.5 W/mK thermal conductivity figure mean for actual CPU temperatures?

The 8.5 W/mK rating indicates high heat-transfer capability, helping lower CPU temperatures under load when paired with a competent cooler.

Is this paste electrically conductive or capacitive, and does it cure over time?

The compound is non-capacitive and non-electrically conductive, eliminating short-circuit risk, and it does not cure, maintaining performance for at least 8 years.
