Main highlights

Super price performance: Arctic’s super price-performance ratio: A high-performance thermal compound for system integrators that surpasses your expectations due to its low price.
Safe use: The ARCTIC MX-4 is a metal-free and non-electrically conductive paste. This formula reduces the risk of short circuits and offers perfect protection for your computer.
Easy to apply. Thanks to the consistency, the MX-4 is easy to apply even for beginners. Ideal for use on chips. Avoid airspace between CPU & cooler by applying a point.
Durable: Long shelf life: Compared to metal or silicone heat transfer pastes, you do not have to compromise with the MX-4. Once applied, it will last at least 8 years!
Better than liquid metal: The ARCTIC MX-4 thermal compound made from carbon micro-particles guarantees extremely high thermal conductivity. Thus the heat is dissipated quickly and efficiently from the CPU/GPU. Viscosity: 870 poise.

Main highlights

Safe for all devices: MX-7 is electrically non-conductive and non-capacitive, so it is completely safe for CPUs, GPUs, laptops, consoles and other devices and there is no risk of short circuits or electrical discharges.
Perfect use: MX-7 cannot be distributed manually due to its nature. Due to its low adhesion, the paste spreads naturally under the pressure of the cooler, forming a thin bonding layer without trapping air bubbles.
Next generation thermal performance: MX-7 is characterised by a performance-optimised, dense and highly viscous consistency. Its high filler content ensures exceptional heat transfer.
Long-term stability: the high cohesion prevents pumping, drying out or bleeding even during repeated temperature cycles and ensures long-lasting and consistent performance without the need for frequent reapplication.
Effortless cleaning with MX Cleaner: removes old thermal paste thoroughly and prepares the contact surfaces for optimal performance. Also available as a handy bundle with MX-7.
