Product information

Description

ARCTIC MX-4 thermal compound with carbon micro-particles provides high thermal conductivity to efficiently dissipate heat from CPUs and GPUs. The product is delivered in optimised, recyclable packaging that reduces packaging material impact by about 40% compared with the previous design, helping to lower the overall CO2 footprint.

Advantages

The MX-4 offers strong thermal performance without containing metallic particles, eliminating electrical conductivity risks. Its creamy consistency makes it easy to apply for both beginners and experienced users. The compound maintains its effectiveness over time and typically does not require reapplication for years after correct application.

Key specifications

Filler: carbon micro-particles
Electrical conductivity: non-metallic, electrically non-conductive
Packaging: optimised recyclable bag (approx. 40% less packaging material impact)
Durability: long-lasting performance, works for multiple years without reapplication
Application consistency: medium / easy-to-spread

How to use

Clean CPU/GPU heatspreader and cooler contact surface thoroughly before application. Apply a small amount of MX-4 in the center of the chip and mount the cooler so the pressure spreads the compound thinly and evenly; this method minimises air gaps and ensures optimal thermal contact. For detailed application techniques and tips to avoid voids, follow the manufacturer's instructional video or manual.

Recommendations

Use on processors, graphics chips and other heat-generating components where a non-conductive, long-lasting thermal interface is required. Avoid contact with exposed electrical contacts and follow standard precautions when mounting coolers.

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.

Better than Liquid Metal

The ARCTIC MX-4 compound is composed of carbon micro-particles which provide extremely high thermal conductivity. It guarantees 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.

Easy to Apply

With an ideal consistency, the MX-4 is very easy to use, even for beginners. The possible application methods and the most effective way to avoid voids between the 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, it ensures that contact with any electrical pins will not cause damage.

High Durability

In contrast to metal and silicone 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.

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.
