ARCTIC COOLING MX-4 2019 Edition 20g thermal paste

High-Performance Thermal Compound for Demanding

ARCTIC COOLING MX-4 2019 Edition is a carbon-based thermal paste rated at 8.5 W/mK conductivity. It is designed for CPU and GPU interfaces in systems where efficient heat transfer matters. The 20g syringe suits enthusiasts, overclockers and builders who want a non-conductive compound with long-term stability. It contains no metallic particles, eliminating the risk of short circuits on exposed pins.

Wide Operating Range and Easy Application

The compound remains stable from -50 °C to +230 °C, covering extreme cooling and heavy load scenarios. Its consistency allows smooth spreading directly from the syringe, making application straightforward for beginners and experienced users alike. Because it contains no metal oxides or liquid metal, it will not corrode cooler bases or stain surfaces. The non-conductive formula ensures safe use around sensitive PCB components.

Sustained Performance Without Dry-Out

MX-4 maintains its thermal resistance over years of continuous cycling, outlasting typical hardware upgrade cycles. Unlike some metal or silicon pastes, it does not pump out, harden or degrade under sustained high temperatures. This reliability means a single application lasts until the cooler or component is replaced. It is not intended for buyers who need electrically conductive paste for specific exotic cooling loops.
