Arctic MX-7: Thermal paste promises "ultimate cooling performance"

Arctic GmbH, formerly known as Arctic Cooling, which is based in Braunschweig, has introduced the Arctic MX-7, a new thermal compound that is designed for "ultimate cooling performance" and "for the highest demands". In the manufacturer's tests, the predecessor, the Arctic MX-6, is clearly beaten. On a powerful Intel Core Ultra 9 285K with ~ 284 watts, the "MX-7" achieves a 2.3 °C lower temperature than the "MX-6", while the "MX-4" can be "undercut" by 4.1 °C. According to the Swiss cooling experts, the optimized formulation should have further reduced the thermal conductivity resistance.

Due to its comparatively viscous, performance-optimized consistency, the Arctic MX-7 cannot be distributed with a spatula, but is distributed "evenly and without air inclusions" by the contact pressure of the cooler, according to the manufacturer. The "MX-7" is thus classified between the "MX-6" and the old "MX-4".

The new Arctic MX-7 is designed to ensure long-lasting stability for "constant performance without drying out" due to its strong internal bonding, high cohesion, and to prevent a "pump-out effect" as well as cracks or leakage even during repeated heat cycles with high thermal stress.

Depending on the package size, the new Arctic MX-7 is now available at prices starting at 6.49 euros for 2 grams, 6.99 euros for 4 grams and 8.49 euros for 8 grams, while the price recommendations are significantly higher and can be found in the manufacturer's in-house online shop.
