High-Performance Thermal Compound for CPU and GPU Cooling
The ARCTIC MX-4 is a carbon micro-particle thermal compound engineered for efficient heat transfer between processors and cooling systems. With 8.5 W/(mK) thermal conductivity, this 4g syringe provides reliable performance for system builders, overclockers, and PC enthusiasts.
Carbon Micro-Particle Formula
Composed of carbon micro-particles, the MX-4 delivers high thermal conductivity without the risks associated with metallic compounds. The non-conductive formula ensures that accidental contact with electrical pins or circuits will not cause damage, making it safer than silver or copper-based alternatives.
Straightforward Application Process
The MX-4 features an ideal consistency that simplifies application for both beginners and experienced builders. The included spatula allows for precise spreading across CPU and GPU surfaces. The compound's viscosity of 870 poise ensures it stays in place during installation while remaining easy to work with.
Long-Term Reliability
Unlike metal and silicon-based thermal compounds that degrade over time, MX-4 maintains consistent performance for at least 8 years after application. This durability eliminates the need for frequent reapplication, reducing maintenance requirements for your cooling system.
