Arctic introduces the MX-7, a further development of the proven thermal compound series, which has been specially designed for the highest demands on cooling performance. Compared to its predecessor MX-6, it offers a measurable temperature reduction and long-term stability. This paste is ideal for high-end CPUs in gaming PCs and workstations, where minimal heat development is crucial.
- Up to 2 Kelvin better cooling performance than MX-6 in tests with Intel Core Ultra 9 285K.
- Viscous consistency prevents air pockets and drying out over years.
- Non-conductive, low adhesion minimizes risks during disassembly.
- Available from 6.49 euros in sizes from 2 to 8 grams.
Optimized formula for maximum heat dissipation
The Arctic MX-7 is based on a newly developed formula that further reduces thermal resistance and thus enables a noticeable increase in performance. In the manufacturer’s internal tests with an Intel Core Ultra 9 285K at 4.5 GHz and around 284 watts TDP, the paste performs around two Kelvin better than the MX-6. This improvement is particularly noticeable in demanding applications such as overclocking or continuous load in games, where every temperature level counts.
The consistency of the MX-7 is deliberately designed to be viscous, which has advantages and disadvantages. On the one hand, it makes it difficult to apply with a spatula, but Arctic recommends a simple cross pattern directly on the heatspreader of the CPU anyway. When attaching the cooler, the paste is then evenly distributed by the contact pressure. The high viscosity and strong internal bonding (cohesion) ensure low-air application and long-lasting stability without the paste drying out or losing its properties.
In addition, the MX-7 has low adhesion, meaning it only adheres weakly to surfaces. This makes it easier to remove the cooler and CPU without leaving any residue. As the paste is not electrically conductive, there is no risk of short circuits or discharges – a decisive advantage for hobbyists and professionals alike.
Practical application and comparison with the previous generation
Compared to the MX-6, which was already established as a reliable option, the MX-7 offers specific optimizations for more demanding scenarios. The MX-4 lagged behind in the tests, while the MX-5 was discontinued due to earlier problems. Arctic is clearly positioning the MX-7 as a top product for users looking for consistent cooling performance without compromise, such as high-end gaming rigs with the latest generation Ryzen or Intel CPUs.
The manufacturer advises minimal material requirements for use: a small cross on the CPU is sufficient, as the pressure does the rest. Optional bundles contain cleaning cloths (MX Cleaner) that make it easier to prepare the surfaces. The paste remains stable for years, which saves costs in the long term as frequent reapplications are no longer necessary. Overall, the MX-7 combines ease of use with professional performance, suitable for builds from beginner to enthusiast.
Conclusion
With its improved thermal conductivity and stable consistency, the Arctic MX-7 meets the highest demands for cooling pastes. It measurably outperforms the MX-6 and offers freedom from risk thanks to its non-conductive properties. Available now from 6.49 euros (2 g) to 8.49 euros (8 g), with bundles from 8.29 euros – ideal for all those who want to keep their systems at top temperatures.
