Arctic launches MX-7, its coolest thermal paste ever

Through its improved formula, MX-7 promises improved thermal performance and longevity, even when it's up against the hottest hardware.

For the past three years, Arctic has been working behind the scenes on improving its thermal compound formula, and it’s now launching the seventh iteration of its MX paste, naturally dubbed MX-7. This new grey goo promises improved thermal performance that could make it the new go-to paste for DIY PC builders.

The biggest changes from the previous formula are lower thermal resistance and higher cohesiveness. These qualities together should deliver better temperatures and a longer lifespan for all applications. Arctic is confident such improvements will apply to all use cases, whether you’re considering the compound for your next CPU installation or GPU repaste. You could even use it to refresh an older game console.

Note, however, that Arctic explicitly discourages applying MX-7 with a spatula on account of the compound’s low adhesion and high viscosity. Instead, the brand recommends adopting the cross method during application.

I’m usually an advocate for the line or blob method. However, following Arctic’s instructions while using MX-7 for our Ryzen 5 7500X3D vs. Ryzen 7 7800X3D guide proved fruitful, with pleasingly low temperatures from each chip.

Putting MX-7 up against a meatier chip, like Intel’s Core Ultra 9 285K, Arctic claims its new formula handily outperforms its prior-generation paste. A difference of 2.3°C may not seem like much in real terms, but it’s major in the world of thermal compounds. Regardless, everyone with a gaming PC can get behind the principle of lower temperatures.

I’m curious to see how differences manifest on a more unruly chip, such as an Intel Core i9-14900K, but I’d settle for AMD’s top-performing Ryzen 9 9950X3D as well. Club386 contributor Krzysztof plans to put MX-7 through its paces in a classic showdown here soon, so keep your eyes peeled for that coverage when it lands.
