White syringe with grey plunger and black tip, 8 g thermal paste

ARCTIC COOLING

ARCTIC COOLING MX-5 8 g thermal paste

SKU CH-1FN2-WC6A6

High-performance thermal paste for CPUs and GPUs, metal-free and non-conductive for safe application

  • Metal-free formula prevents short circuits and corrosion
  • Thin bondline fills micro-pores for lower thermal resistance
  • Easy-spread viscosity enables even, thin layers every time
  • Works on CPUs, GPUs and power semiconductors alike
  • Resealable packaging keeps paste fresh for future use

ARCTIC MX-5 8 g thermal compound

ARCTIC MX-5 is a high-performance thermal paste designed for CPUs, GPUs and power semiconductor components in PCs and consoles. The metal-free formula eliminates the risk of electrical shorts and corrosion on cooler bases. Its viscosity allows a thin, even layer regardless of application method. Resealable packaging keeps the compound from drying out between uses.

Practical limits of thermal paste

Thermal paste only fills microscopic gaps between a die and a cooler; it cannot compensate for poor mounting pressure or warped surfaces. The compound is non-conductive, so accidental contact with surrounding components will not cause shorts. Long-term durability is rated for years, but pump-out cycles may eventually require re-application. No paste can overcome a cooler that is fundamentally undersized for the heat load.

8 g syringe capacity

The 8 g syringe provides enough compound for multiple CPU and GPU applications. Larger 50 g variants exist for system builders who need higher volume. Choose this size if you service a few systems occasionally; step up if you re-paste daily. The resealable cap preserves viscosity for the next job.

Questions about this item

Which size of MX-5 should I pick for a single CPU and GPU application?

The 8 g tube covers multiple CPU and GPU installations, and the resealable packaging prevents the paste from drying out between uses.

How does the high thermal conductivity translate to actual temperatures?

The compound fills micro-pores for an extra thin bondline, lowering thermal resistance and allowing a very thin layer that improves heat transfer from CPU or GPU dies.

Is the paste electrically conductive and what does that mean for installation safety?

MX-5 is completely metal-free and non-conductive, so there is no risk of short circuits, discharges or corrosion damage to the radiator bottom during application.
