Thermal paste ARCTIC MX-4 (20 g) Edition 2019

Thermal paste ARCTIC MX-4 (20 g) Edition 2019 is a high-performance thermal compound designed to provide efficient heat transfer between CPUs or GPUs and their coolers. The compound uses carbon micro-particles to achieve a thermal conductivity of 8.5 W/m·K and comes in a 20 g recyclable package introduced to reduce packaging CO2 footprint and resource usage.

Advantages

MX-4 offers high thermal conductivity thanks to its carbon micro-particle formulation, ensuring fast and effective heat dissipation. The compound contains no metallic particles, so it is electrically non-conductive and safe to use near pins and contacts. Packaging has been optimised to reduce environmental impact by approximately 40%. MX-4 maintains its performance over time and, once applied correctly, can remain effective for up to 8 years.

Suitable for

• Applying between CPU and cooler for desktop processors
• Thermal interface for GPU cooling solutions
• System builders and PC enthusiasts requiring long-lasting thermal paste
• Overclocking setups where efficient heat transfer is required

How to use

Clean both contact surfaces (CPU/GPU heat spreader and cooler base) from old paste and dust before application. Apply a small, pea-sized amount of MX-4 in the centre of the chip and mount the cooler to spread the compound evenly; this reduces the risk of air pockets. For alternative application methods or further details on avoiding voids, follow the manufacturer's instructions or reference the official application video.

Usage recommendations

Apply once and avoid reapplying frequently; when applied correctly MX-4 remains effective for years. Store the tube in a cool, dry place and keep the cap closed to maintain consistency. Do not use on open electrical contacts and avoid mixing with metal-based pastes.
