Thermal paste Arctic MX-7 heat sink compound, high-performance thermal interface material

Arctic MX-7 is a high-performance thermal paste formulated as a heat sink compound for CPUs, GPUs and other electronic components that require efficient thermal transfer. Supplied as a thermal interface material, it fills microscopic gaps between a heat source and cooler to improve heat dissipation and reduce operating temperatures. The compound is suitable for system builds, upgrades and repairs where reliable thermal conductivity and long-term stability are required.

Advantages

MX-7 offers improved thermal conductivity compared with standard pastes while maintaining low viscosity for easy application and uniform spread. The compound is electrically non-conductive and non-capacitive, reducing the risk of short circuits in densely packed PCBs and sockets. It is also formulated to resist drying and pump-out over time, supporting stable thermal performance across extended operating periods.

Suitable for

• Desktop and laptop CPU cooling and replacement
• GPU heatsink installation and maintenance
• Heat sink attachment for chipsets, VRMs and other ICs
• System builds, upgrades and routine thermal maintenance

Key specifications

• Thermal interface type: silicone-based heat sink compound
• Thermal performance: formulated for high thermal conductivity suitable for consumer and enthusiast systems
• Electrical properties: electrically non-conductive and non-capacitive
• Viscosity and consistency: low to medium viscosity for controlled application and even spread
• Durability: resistant to drying and pump-out for stable long-term operation
• Compatibility: suitable for metal and ceramic heatsinks and common thermal pad interfaces

How to use

Before applying Arctic MX-7, power down the system and ground yourself to avoid electrostatic discharge. Clean both contact surfaces thoroughly with isopropyl alcohol and a lint-free cloth to remove old thermal compound and debris. Apply a pea-sized amount of MX-7 to the center of the processor or component, then install the heatsink and secure it according to the manufacturer’s mounting procedure; pressure from the heatsink will spread the compound evenly. If preferred, the paste can be manually spread in a thin, even layer prior to heatsink installation. Reassemble the system and verify correct seating and temperatures under load.

Usage recommendations

Use Arctic MX-7 for standard and advanced cooling tasks where a reliable, electrically safe thermal interface is required. Allow time for the compound to settle after initial thermal cycles, and avoid over-application which can reduce thermal transfer efficiency. Replace the compound during major component changes or if thermal performance degrades noticeably over time.
