ARCTIC Launches New MX-5 Thermal Compound
The newly developed, high-performance paste comes with an ideal set of thermal properties, guaranteeing reliable heat dissipation over long periods of time. ARCTIC MX-5 is available now in variants ranging from 2 to 50 grams, with and without a spatula.
Like all thermal pastes from ARCTIC, MX-5 is completely metal-free. Because MX-5 is neither conductive nor capacitive, it is particularly safe to use: the possibility of short circuits, corrosion damage or discharges is eliminated.
Regardless of the application method, applying MX-5 is very easy thanks to its low viscosity. The paste can be evenly distributed across the CPU in an extremely thin film via contact pressure from the heat sink. Combined with high thermal conductivity, this results in very low thermal resistance, which can contribute to improved service life and processor performance
MX-5 uses carbon microparticles as a filler to smooth out small imperfections on heatsinks and heatspreaders, improving heat transfer from the component to the heat sink. It is suitable for use on all CPUs and GPUs, whether they are in PCs, laptops or consoles. MX-5 is also recommended for integrated circuits with high waste heat and for power semiconductor devices.
Availability
The MX-5 is available now at Amazon with a starting price of $5.89 USD.

I hope it will be at least as good as MX-2 and MX-4. My top choice for building standard PCs. For OC intended PCs or as a GPU TIM swap I still prefer Thermal Grizzly, but customers expect and pay for the best in those cases.

im done with thermal paste on cpu since i discovered grizzly carbonaut, easy, clean, durable, you get maybe 1-2 more degree on your temps, but the ease of use and the fact that you dont need to reapply after a while make it worth it to me, its also very practicle on am4 socket

Only if you have it over 1 year applied and your mx-2 tube is now empty

Thermal pads had been used on laptops and other electronics beside desktops for long time now. It is definitely interesting solution but it's practical advantages seems to be just personal preference. I did replace my CPU heatsink after 5 years and the MX-2 was good as new. You for sure don't need to replace it often.
