Small white syringe of thermal paste with grey cap

ARCTIC COOLING

ARCTIC COOLING MX-5 thermal paste 4 g

SKU CH-JTHC-TDG6V

Metal-free thermal compound with carbon microparticles fills microscopic surface gaps for efficient heat transfer from CPUs, GPUs and power components

  • Metal-free formula prevents short circuits and corrosion
  • Carbon microparticle composition enables high thermal conductivity
  • Low thermal resistance from thin bondline capability
  • Non-drying properties maintain long-term performance
  • Easy application with even spread for beginners

Product purpose

ARCTIC MX-5 is a metal-free thermal compound designed to transfer heat between a processor or graphics chip and its cooler. The carbon microparticle formula fills microscopic surface imperfections to achieve high thermal conductivity and very low thermal resistance. It is non-conductive and non-capacitive, removing the risk of short circuits or corrosion on cooler bases. The paste suits CPUs, GPUs and power semiconductor components.

Who it suits

Builders and upgraders who want a safe, easy-to-apply paste for standard desktop or laptop cooling jobs will find the viscosity forgiving and the long-term stability reliable. The resealable packaging keeps the compound usable across multiple installations. Users who require electrically conductive liquid-metal performance or need larger volumes than the 50 gram maximum offering should consider alternative product types.

Bundled value

The syringe package includes a spatula to help spread an even, thin layer and reduce air pockets during application. Resealable packaging prevents the paste from drying out between uses, extending shelf life for future maintenance. No additional software or mounting hardware is supplied with this thermal compound.

Questions about this item

What size syringe or tube does the 4 g version come in, and is the packaging resealable?

The MX-5 is sold in sizes from 2 to 50 grams with resealable packaging that prevents the paste from drying out.

Will this paste work safely on an older GPU that still uses a bare die without an integrated heat spreader?

Yes, MX-5 is metal-free, non-conductive and non-capacitive, so it poses no short-circuit or corrosion risk on bare-die graphics processors.

After applying the paste, how can I verify that the bondline is thin enough for the low thermal resistance the product claims?

The paste’s viscosity lets it spread into a very thin, even layer; if temperatures drop noticeably under load compared to the previous application, the bondline is performing as intended.
