Product information

Description

ARCTIC MX-4 thermal compound combines high thermal conductivity with non-metallic composition and eco-aware packaging. The paste is formulated with carbon micro-particles to transfer heat efficiently from CPU or GPU to the cooler, while its non-conductive formula eliminates the risk of electrical shorting. The packaging has been optimised to reduce material use and CO2 footprint through a recyclable bag design.

Advantages

MX-4 offers strong thermal performance comparable to high-end compounds while remaining electrically non-conductive thanks to its carbon-based formulation. The paste has a user-friendly consistency that simplifies application for beginners and experienced builders alike. Packaging improvements reduce environmental impact by about 40%, and the compound maintains stability and effectiveness for years after application.

Key specifications

  • Composition: carbon micro-particles (non-metallic, electrically non-conductive)
  • Application form: thermal paste
  • Durability: maintains performance for at least 8 years after application
  • Packaging: recyclable bag, packaging material reduced by ~40%
  • Intended use: CPU and GPU heat transfer

How to use

Clean CPU/GPU and cooler contact surfaces from old paste and contaminants before application. Apply a small, even amount of MX-4 to the processor heat-spreader and mount the cooler according to the cooler manufacturer’s instructions to ensure even pressure and avoid air gaps. For step-by-step application techniques and tips on avoiding voids between surfaces, follow the product video or manufacturer guidance.

Recommendations

Use a minimal, controlled amount and secure the cooler evenly to ensure optimal thermal contact. Store the paste at room temperature and reseal packaging after use to maintain shelf life.

Reasons to buy

Optimised Packaging Saves Resources

A sustainable use of resources is very important to us at ARCTIC. Thus, we updated the packaging of the MX-4 to minimize its CO2 footprint.

The practical, recyclable packaging bag of our thermal compound helps reduce the environmental impact of packaging materials by about 40% and thereby saves resources.Optimised Packaging Saves Resources

Better than Liquid Metal

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

Easy to Apply

With an ideal consistency, the MX-4 is very easy to use, even for beginners. The recommended application methods and the most effective way to avoid voids between CPU and cooler are shown in the video.

Safe Application

It does not contain any metallic particles, so electrical conductivity is not an issue. Unlike silver and copper compounds, contact with any electrical pins will not cause damage.Safe Application

High Durability

In contrast to metal and silicon thermal compounds, the performance of MX-4 does not degrade over time. Once applied, you do not need to reapply it — it will last at least 8 years.High Durability

Value for Money

A high-performance thermal compound perfect for system builders — it's no surprise that the MX-4 exceeds expectations given its low price.Value for Money
