ARCTIC MX-4 is a thermal paste for transferring heat between a processor or graphics chip and its cooler. The 20 g syringe suits PC builders, upgrade projects and repair work where paste is needed for a CPU, GPU or another application requiring thermal transfer.

Its microparticle-based compound fills microscopic unevenness between the chip and cooler surface, helping heat move away efficiently. The paste is metal-free and non-electrically conductive, so it avoids the electrical conductivity associated with metal-based compounds. Its consistency is designed for straightforward application, including for people new to fitting thermal paste. ARCTIC also describes the formula as non-drying and non-bleeding, supporting consistent performance over time. The resealable packaging helps prevent the paste from drying out between uses.

Key features

• Transfers heat from CPU and GPU surfaces to their coolers.
• Microparticles fill small surface imperfections between chip and cooler.
• Metal-free compound is not electrically conductive.
• Consistency makes application manageable for beginners.
• Non-drying and non-bleeding properties support long-term performance.
• Resealable packaging helps keep unused paste from drying out.
• 20 g content provides paste for multiple applications.

Compatibility

Use MX-4 between a compatible processor or graphics chip and its cooler, following the cooler and processor fitting guidance. It is intended for thermal transfer applications and is not a cooler itself. Good to know: this 20 g version is the paste syringe; a cooler, application tools and other accessories are not included with it.

Specifications

For a PC rebuild, a cooler replacement or a graphics card maintenance job, MX-4 provides a non-conductive thermal interface compound in a generous 20 g size. Its easy-to-apply consistency and resealable packaging make it a practical choice when you need paste for more than one installation or want some available for later maintenance.
