What the product is

Arctic MX-4 AC-MX4 is a 4 g syringe of carbon microparticle thermal compound rated at 8.5 W/mK conductivity. It is electrically non-conductive and non-capacitive, so accidental contact with surrounding circuitry will not cause shorts. The paste does not cure, bleed or corrode, making it suitable for CPUs, GPUs and other electronic components that need reliable heat transfer.

What to check before ordering

Verify that the component you intend to cool has a flat, clean mating surface and that any old compound has been fully removed with isopropyl alcohol. The 4 g volume covers several applications, but plan for one syringe per major reseat. No specific socket, mounting pressure or cooler type is required beyond normal thermal-interface practice.

Thermals noise and power draw

With a thermal conductivity of 8.5 W/mK, density of 2.5 g/cm³ and viscosity of 870 poise, the compound fills microscopic gaps efficiently and maintains stable contact under normal operating temperatures. Being non-curing, it avoids pump-out effects over time. The material itself produces no noise and draws no power; thermal performance depends on cooler capacity and airflow in your system.

Perguntas sobre este artigo

What comes in the box and do I need any extra tools to apply the paste?

The package contains a 4 g syringe of MX-4 compound; no spatula or spreader is included, but the paste’s consistency allows direct application and simple spreading with the syringe tip or a clean finger in a glove.

How do I decide between the 4 g syringe and larger sizes?

The 4 g syringe covers several CPU or GPU applications; choose a larger tube only if you service many systems or plan repeated re-pasting.

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

It indicates high thermal conductivity that moves heat from the die to the cooler efficiently, helping lower peak temperatures under load compared with standard pastes.
