Thermal paste ARCTIC MX-4 (8 g) Edition 2019

The ARCTIC MX-4 (8 g) Edition 2019 is a high-performance thermal paste designed to improve heat transfer between CPU/GPU and heatsink. With a thermal conductivity of 8.5 W/m·K and a density of 2.5 g/cm³, this non-metallic compound provides efficient cooling while being electrically non-conductive. The 8 g syringe comes in optimised, recyclable packaging that reduces packaging material impact by about 40%.

Advantages

MX-4 uses carbon micro-particles for high thermal conductivity while remaining free of metallic particles, so it is electrically safe for use around pins and contacts. The paste has a stable consistency that is easy to apply, suitable for both beginners and experienced builders. Its performance remains stable over time and the manufacturer states a durability of at least 8 years after application. The 2019 edition balances thermal performance and value for money for system builders and enthusiasts.

Suitable for

• Improving heat transfer between CPU and cooler
• GPU cooling applications where a non-metallic paste is preferred
• PC builds, overclocking and system upgrades
• System builders and repair/maintenance tasks

Key specifications

• Thermal conductivity: 8.5 W/m·K
• Weight: 8 g (0.008 kg)
• Density: 2.5 g/cm³
• Product colour: Blue, White
• Pack type: Single syringe, recyclable packaging
• Made in: Hong Kong

How to use

Ensure both surfaces (CPU/GPU heatspreader and heatsink base) are clean and free of old thermal compound, dust and grease. Apply a small, pea-sized amount of MX-4 in the centre of the processor heatspreader, then mount the cooler and secure it following the cooler manufacturer’s instructions; the pressure spreads the paste evenly. For larger IHS or specific mounting methods, refer to the application video or manufacturer guidance for techniques that minimise air gaps.

Usage recommendations

Store the syringe at room temperature and avoid direct sunlight. Reapply only if thermal performance degrades or after removing the cooler; MX-4 is rated to remain effective for at least 8 years under normal conditions. Avoid contact with electrical contacts despite the non-metallic composition, and follow standard ESD precautions when working inside a PC.
