ARCTIC MX-4 2019 Edition 8.0g thermal paste

The ARCTIC MX-4 2019 Edition is a carbon-based thermal compound designed for CPU and GPU heat transfer. It suits PC builders and upgraders who need reliable thermal interface material for air or liquid coolers. The 8.0g syringe provides enough paste for multiple applications across different components.

Carbon micro-particle formula

This paste uses carbon micro-particles to achieve 8.5 W/mK thermal conductivity without metallic content. It is non-electrically conductive, non-capacitive and non-corrosive, eliminating short-circuit risk if it contacts surrounding circuitry. The 870 poise viscosity and 2.5 g/cm3 density give a stable, non-bleeding spread that does not cure or dry out over time.

Check syringe volume and application method before

Verify that 8.0g covers your planned installations, as larger multi-GPU or delidding projects may need more material. Ensure you are comfortable with manual syringe application and spreading technique, since no applicator tool is included. Buyers who want pre-applied pads or metallic liquid-metal compounds should consider other product types.

It is an electrically non-conductive paste that is applied between CPU / GPU and designated coolers to transfer the dissipated heat from the components to the heat sink. Since the ARCTIC MX-4 is a metal-free compound, it eliminates the risks of causing short circuit and in turn adding more protection to your computer.

Questions about this item

How does the 8.5 W/mK thermal conductivity limit real-world heat transfer?

The 8.5 W/mK rating means heat moves efficiently from the CPU or GPU into the cooler, keeping temperatures lower under sustained loads.

What physical space does the 8.0 g syringe need for storage and dispensing?

The compact syringe fits in a standard tool drawer; the nozzle reaches tight gaps around socket keep-out zones without extra adapters.

How is the paste applied, and what step do builders often skip?

Squeeze a pea-sized dot onto the centre of the heat spreader, mount the cooler straight down, and let pressure spread it — skipping the centre-dot step creates air pockets.
