Model N/A

  • Electrically non-conductive carbon formula prevents short-circuit risk
  • 5 W/mK thermal conductivity transfers heat efficiently from CPU or GPU
  • Non-curing compound stays effective without drying out over time
  • 870 poise viscosity allows smooth, controlled syringe application
  • 5 g/cm³ density ensures consistent coverage with minimal paste

Carbon Microparticle Thermal Paste

ARCTIC MX-4 is a carbon microparticle thermal compound designed for CPU and GPU heat transfer. The non-conductive formula eliminates electrical risk if paste spreads beyond the die. It suits builders who want reliable performance without the hazard of metal-based pastes.

Replaces Degrading Pastes

Unlike metal or silicon compounds, this material does not cure, bleed or corrode over time. The jump is worth it when replacing dried-out stock paste or conductive compounds that risk shorting components. Long-term stability means re-application intervals can be extended.

Fits Standard Syringe Workflow

The 2g syringe dispenses cleanly for direct die or spread application on desktop and laptop coolers. Low thermal resistance of 8.5 W/mK and viscosity of 870 poise allow thin, even layers without specialized tools. Density of 2.5 g/cm3 ensures the paste stays in place under mounting pressure.

Questions about this item

What size syringe tip fits the 2g tube for precise CPU application?

The 2g syringe dispenses directly through its built-in nozzle; no separate tip is required and the paste's 870 poise viscosity allows controlled placement on the CPU heat spreader.

How do I apply the carbon-based compound without creating air bubbles?

Place a pea-sized drop in the centre of the CPU, then mount the cooler straight down — the pressure spreads the 8.5 W/mK paste evenly without trapping air.

Will the thermal paste dry out or need replacement after a few years?

The carbon microparticle formula is non-curing and non-bleeding, so it maintains its 2.5 g/cm³ density and does not degrade like metal or silicone compounds.
