ARCTIC MX-4 is a thermal paste for transferring heat between a processor and its cooler. This 4 g version with a spatula suits PC builders and anyone replacing paste during a CPU or GPU cooling service.

Its microparticle compound fills tiny surface irregularities between the chip and cooler base to help heat dissipate efficiently. The paste is easy to apply, including for beginners, and its non-drying and non-bleeding properties support consistent long-term performance. MX-4 is metal-free and not electrically conductive, making it a practical choice for routine system building and maintenance.

Key features

• Designed to transfer heat from CPU or GPU surfaces to a cooler
• Microparticles fill microscopic dents between mating surfaces
• Easy-to-apply consistency suits beginners as well as experienced builders
• Non-drying and non-bleeding properties support long-term performance
• Metal-free formulation is not electrically conductive
• Includes a spatula to help spread the paste during application
• 4 g quantity for application during a build or maintenance task

Compatibility

Use between a processor chip and its cooler base, following the application instructions for your cooler and processor. This is thermal compound rather than a cooler, so it does not provide the heatsink or fan. Good to know: the CPU cooler is not included, and the paste must be applied to clean mating surfaces before fitting the cooler.
