Thermal paste for CPU and GPU installs

This 4.0 g syringe of ARCTIC MX-4 2019 Edition thermal compound suits DIY builders and system integrators who need reliable heat transfer between a processor and cooler. The paste delivers 8.5 W/mK thermal conductivity and a viscosity of 870 poise for consistent coverage. It is non-conductive with a volume resistivity of 3.8 x 1013 ohm-cm, so accidental contact with components is safe. The 2019 formulation aims for high durability and value for money.

Ideal for standard desktop builds not liquid metal

The compound works well for anyone assembling or servicing air-cooled or all-in-one liquid-cooled systems who prefers a forgiving, non-conductive paste. It is not suited for enthusiasts chasing the absolute lowest temperatures possible with liquid metal, nor for applications requiring electrically conductive thermal interface material. Users who need larger volumes for multiple builds may find the 4.0 g syringe limiting.

Four-gram syringe covers several mainstream sockets

At 4.0 g and a density of 2.5 g/cm3 the tube provides enough paste for multiple CPU or GPU applications on typical desktop platforms. A single application uses a small fraction of the volume, leaving headroom for future reapplies or a second component. The syringe will run out after many installs or if used on oversized cold plates, so high-volume workshops should plan for additional units.

商品問答

What CPU cooler or water block must I already have to use this 4.0 g syringe of MX-4 2019 Edition paste?

Any standard air cooler or water block with a flat cold plate works; the paste is non-conductive and safe for all common mounting hardware.

Will the 8.5 W/mK conductivity and 870 poise viscosity perform reliably on an older CPU with a larger die and uneven IHS?

Yes, the high viscosity fills microscopic gaps on larger or slightly concave dies without pumping out, maintaining stable contact over time.

How can I verify the paste is spreading correctly after I mount the cooler?

Remove the cooler and check for a thin, uniform layer covering the entire IHS with no voids; the grey compound should appear evenly distributed.
