Key item features

  • Optimal Thermal Performance: The extra thin bondline perfectly fills micro-pores, leading to lower thermal resistance and potentially stronger adhesion for efficient heat transfer.
  • Broad Compatibility: This thermal paste is suitable for a wide range of applications, including CPUs, GPUs, and power semiconductor components, making it versatile for various devices.
  • Enhanced Safety: Being completely metal-free, the ARCTIC MX-4 eliminates risks of short circuits, electrical discharges, and corrosion damage to the radiator bottom.
  • Effortless Application: Its ideal viscosity ensures easy application, allowing for even spreading and the formation of a very thin layer regardless of the chosen method.
  • Diverse Sizing Options: Available in multiple variants ranging from 2 to 50 grams, with resealable packaging to prevent drying out, and an optional spatula for convenience.
  • Superior Heat Conductivity: The ability to apply a particularly thin layer, combined with high thermal conductivity, results in very low thermal resistance for excellent cooling.

The Best Bang for Your Buck

I've used MX-4 for everything from repasting older CPUs to high-power LED flashlight heatsinks and even audio equipment repair. For the price and quality, you really can't beat the heat conductivity. It's affordable, reliable, and my go-to for any project where performance and value are the priority. Highly recommend keeping a tube in your toolkit.
