Well Proven Quality

The design of our thermal paste packagings has changed several times over the years.
The formula of the composition has remained unchanged, so our MX pastes have stood for high performance and quality for years.

Award Winning Thermal Paste

The performance of our ARCTIC MX-4 Thermal Compound has been tested and honored by numerous independent magazines.

Optimised Packaging Saves Resources

A sustainable use of resources is really important for us at ARCTIC. Thus we updated the packaging of the MX-4 to minimize it's CO2 footprint.

The practical, recyclable packaging bag of our thermal paste helps us to reduce the environmental impact of packaging materials by about 40 % and thereby save resources

Better than Liquid Metal
The ARCTIC MX-4 compound is composed of carbon micro-particles which lead to an extremely high thermal conductivity. It guarantees that heat generated from the CPU or GPU is dissipated quickly and efficiently. Superb in performance, MX-4 is the best companion for overclockers and enthusiasts.

Easy to Apply

With an ideal consistency, the MX-4 is very easy to use, even for beginners. The possibilities for its application and the most effectively way to avoid voids between CPU and cooler we show you in the video.

Safe Application

It does not contain any metallic particles so electical conductivity would not be an issue. Unlike silver and copper compound, it ensures that contact with any electrical pins would not result in damage of any sort.

High Durability

In contrast to metal and silicon thermal compound, the performance of MX-4 does not compromise over time. Once applied, you do not need to apply it a second time as it will last at least for 8 years.

Value for Money

A high performance thermal compound perfect for system builders, there's no suprise that the MX-4 exceeds your expectations for its low price tag.
