ARCTIC MX-4 thermal paste is highly regarded among computer enthusiasts because its composition provides extremely good thermal conductivity, making it one of the best pastes on the market. Since it does not contain metal particles, it is not electrically conductive, which means it can be safely applied to your processor. Its durability is estimated at a minimum of 8 years.

Thermal conductivity: 8.5 W/(mK)
Density: 2.5 g/cm³
Weight: 20g
