ARCTIC MX-4 is a 4 g thermal paste for fitting between a processor or graphics chip and its cooler. It suits PC builders and enthusiasts refreshing a CPU or GPU cooler, as well as beginners carrying out a first thermal paste application.

Microparticles in the compound fill microscopic uneven areas between the chip and cooler base, helping heat transfer from the CPU or GPU. Its consistency is designed to make application manageable, while non-drying and non-bleeding properties support steady performance over time. MX-4 is metal-free and not electrically conductive, making it a practical option for routine cooler installation and maintenance. This 4 g version comes without a spatula and uses resealable packaging to help prevent the remaining paste from drying out.
