Arctic MX-5 is a new thermal paste that improves viscosity and heat transfer between the CPU and the heatsink, compared to the MX-4 model.
Arctic MX-5, a new thermal paste that improves the MX-4
Arctic Thermal Paste uses a new Thermal Interface Material (TIM) that is being designed for CPUs, graphics cards, PCs, laptops, and even game consoles.
The MX-5 is already available worldwide and they say it improves the conductivity of the previous MX-4 thermal paste, although they do not give details on the conductivity or other specifications.
All Arctic Thermal pastes use metal-free materials, so they are neither conductive nor capacitive, something essential when it comes to applying it in such advanced electronic devices to avoid short circuits. These MX-5 thermal pastes ship in 2-50 gram containers and start at $ 5.90. These packages can be purchased with or without the spatula for your application.
Arctic promises to improve heat conductivity with its new MX-5 thermal paste, as well as making it much easier to apply. Apparently, the paste is less viscous than in the previous version so that it spreads much more easily on the surface between the CPU and the heatsink. Being less viscous, the thermal paste layer is thinner and more evenly distributed, improving heat transfer.
The MX-5 uses carbon microparticles as fillers to smooth out small imperfections on the heat sinks and plates.
It is always recommended to replace the CPU thermal paste every so often and the MX-5 seems to be one of the best options.
