Thermal paste ARCTIC MX-4 2019 8 g Thermal conductivity 8.5 W/m·K

ARCTIC MX-4 2019 is a high-performance thermal paste in an 8 g package that provides efficient heat transfer between CPU/GPU and cooler. With a thermal conductivity of 8.5 W/m·K and a density of 2.5 g/cm³, MX-4 uses carbon micro-particles to achieve high thermal performance without metallic components. The product is supplied in a recyclable packaging bag that reduces packaging material and CO2 footprint.

Advantages

MX-4 combines very good thermal conductivity with a non-metallic formulation, eliminating electrical conductivity risks associated with silver or copper pastes. The compound has an easy-to-apply consistency suitable for users of different skill levels and maintains stable performance over long periods — ARCTIC specifies durability of up to 8 years after application. The packaging has been optimised to reduce environmental impact by around 40% compared with the previous packaging design.

Suitable for

• Thermal interface between CPU and cooler
• Thermal interface between GPU and cooler
• System builders and PC enthusiasts performing assembly or maintenance
• Overclocking setups requiring efficient heat dissipation

How to use

Clean both contact surfaces (CPU/GPU and cooler base) from old thermal paste and dust using isopropyl alcohol and a lint-free cloth. Apply a small, pea-sized amount of MX-4 on the centre of the CPU or GPU die. Mount the cooler and tighten the fasteners evenly to spread the compound and avoid gaps. For detailed application techniques and visual guidance, refer to the manufacturer's instructional video.

Usage recommendations

Apply only the amount necessary to create a thin, even layer; excessive paste does not improve thermal transfer. Avoid contact with electrical pins. Store the product in a cool, dry place and reseal the tube after use. Reapplication is generally not required for up to 8 years under normal operating conditions.
