With its improved composition, the ARCTIC MX-6 has a measurably lower thermal resistance than the MX-4. ARCTIC measured the absolute thermal resistance of both pastes on their lab-testing machine, which is much more accurate than a CPU. Two factors are mainly relevant:

• Conductivity
• Minimum Bond Line thickness

A lower thermal resistance of the paste leads to a lower temperature difference between CPU and cooler. The ARCTIC MX-6 reaches its maximum performance without burn-in, directly after application and distribution. It achieves all of this without any reputed ingredients, such as expensive diamond dust or various precious metal particles. The silicone gel used as a carrier enables optimal distribution, which is achieved through even contact pressure, for example when mounting the heat sink.
