ARCTIC COOLING

ARCTIC COOLING MX-4 Thermal Paste 4g with Spatula

SKU CH-74JD-0466T

Carbon-based thermal compound for CPU and GPU cooling, metal-free and non-conductive with a spatula included for easy application

  • Carbon microparticles deliver high thermal conductivity for efficient heat dissipation
  • Metal-free, non-conductive formula eliminates short-circuit risk on CPU and GPU
  • Consistent viscosity allows easy, bubble-free application even for beginners
  • Formula unchanged over years — proven reliability across multiple packaging revisions
  • Rated to last at least eight years without re-application

Proven Carbon-Based Compound

ARCTIC MX-4 is a carbon microparticle thermal paste supplied in a 4-gram syringe with an included spatula. The formula has remained unchanged across packaging revisions, delivering consistent high thermal conductivity for CPU and GPU heat dissipation. Its metal-free, non-electrically conductive composition eliminates short-circuit risk during application. The compound is rated to maintain performance for at least eight years without reapplication.

Replaces Dried or Stock Paste

This paste upgrades from hardened factory pre-applied material or aged ceramic compounds that have lost efficiency over time. The jump is worth it when temperatures climb under load or when remounting a cooler after maintenance. Builders reusing a heatsink on a new platform benefit from the stable, long-life formula. It is not suited for users needing liquid-metal conductivity levels or sub-ambient cooling setups.

Fits Standard Desktop Maintenance

The 4-gram volume covers multiple CPU applications or a single GPU die with margin to spare. The bundled spatula helps spread an even layer without extra tools. The paste works with all common air and liquid coolers that mount on standard processor heat spreaders. No curing time or special surface preparation beyond cleaning is required. It does not address thermal-pad replacements on VRAM or VRM components.

Questions about this item

Does the 4 g syringe include a tool for spreading the paste?

Yes, a spatula is supplied in the package for applying the compound.

How should I apply the paste to avoid trapping air between the CPU and cooler?

Use the included spatula to spread a thin, even layer or place a small pea-sized dot in the centre before mounting the cooler; the paste's consistency helps prevent air pockets.

How often will I need to replace this thermal compound after applying it?

The carbon-based formula is rated to last at least eight years, so re-application is not required during that period.
