ARCTIC COOLING

ARCTIC COOLING MX-4 Thermal Paste 4.0 g

SKU CH-NFZA-XT01B

Thermal compound with 8.5 W/mK conductivity and 4.0 g net weight for CPU and GPU coolers

  • Easy application with non-curing, non-bleeding consistency
  • High thermal conductivity rated at 8.5 W/mK for efficient heat transfer
  • Electrically non-conductive and non-capacitive for safe use near components
  • Non-corrosive formula protects metal surfaces over time
  • 0 g net weight supplied in a convenient syringe

Thermal Compound for All Coolers

ARCTIC MX-4 is a thermal compound designed for use with any CPU or GPU cooler. The 4.0 g syringe provides enough material for multiple applications. It offers a thermal conductivity of 8.5 W/mK and a viscosity of 870 poise for consistent spreading.

Suits builders needing reliable non-conductive paste

This paste suits system builders who want an electrically non-conductive, non-capacitive compound that will not cure, corrode or bleed over time. It is not for users who require a liquid-metal thermal interface for extreme overclocking scenarios.

Check cooler mounting pressure and surface flatness

Before ordering, verify that your cooler mounting mechanism provides even pressure across the die or heatspreader. Ensure the mating surfaces are clean, flat and free of old compound residue to achieve the specified low thermal resistance.

Questions about this item

What cooler mounting hardware do I need to use with this 4.0 g syringe?

The paste works with any standard CPU or GPU cooler; you only need the cooler and its supplied brackets.

Will the 8.5 W/mK conductivity remain stable on a ten-year-old copper base?

Yes, the non-curing formula keeps its performance on aged copper or aluminium without hardening.

How can I confirm the 870 poise viscosity is right after I spread it?

A thin, even layer that does not ooze when the cooler is tightened shows the paste is seated correctly.
