Features

  • CONSISTENT QUALITY: Our thermal paste packaging design has evolved over time, but the formula has remained the same, ensuring reliable performance.
  • EXCELLENT PERFORMANCE: ARCTIC MX-4 thermal paste is made of carbon microparticles, guaranteeing extremely high thermal conductivity. This ensures that heat from the CPU/GPU is dissipated quickly & efficiently
  • SAFE APPLICATION: The MX-4 is metal-free and non-electrical conductive which eliminates any risks of causing short circuit, adding more protection to the CPU and VGA cards
  • HIGH DURABILITY: In contrast to metal and silicon thermal compound, the MX-4 does not compromise over time. Once applied, you do not need to apply it again as it will last at least for 8 years
  • EASY TO APPLY: With an ideal consistency, the MX-4 is very easy to use, even for beginners

  • Not just for computers!
I used this when I attach a small heat sink to a fan motor for my garage heater. Worked really well for the application and should add years to the fan motors life. No longer runs hot! Came with far more paste than I thought it would. Really like the applicator. Easy to use. Easy to clean up.
