Thermal paste Arctic MX-7 ULTIMATE Performance, 8 g, density 2.9 g/cm³, grey

Arctic MX-7 ULTIMATE Performance is a grey thermal paste supplied in an 8 g tube with a density of 2.9 g/cm³ and an operating temperature range from −50 to 250 °C. It is formulated to fill microscopic gaps between CPU or GPU surfaces and heatsinks to improve thermal contact and heat transfer in desktop PCs and laptops. The compound is electrically non-conductive and designed for repeated application during routine maintenance or cooler upgrades.

Advantages

MX-7 ULTIMATE Performance provides low thermal resistance through a thin bond line that enhances cooling efficiency without changing the mechanical fit between cooler and processor. The product is easy to apply and spread, remains stable across the specified temperature range, and is suitable for long-term use. Its grey composition maintains consistent performance over time and is compatible with a wide range of metal and ceramic heatsink bases.

How to use

Clean both the processor and heatsink surfaces with isopropyl alcohol and a lint-free cloth to remove old thermal compound and contaminants. Apply a small, pea-sized amount of Arctic MX-7 ULTIMATE Performance to the centre of the die or IHS, then mount the cooler and secure it according to the manufacturer's instructions so the paste spreads evenly. For larger dies or GPUs, adapt the amount and placement to ensure a thin, continuous layer without excess overflow. When removing the cooler, re-clean surfaces and reapply fresh compound as needed.

Recommendations

For best thermal contact, use only a thin, continuous layer of paste; avoid over-application which can increase thermal resistance or create cleanup issues. Allow the system to run through a few thermal cycles after application to let the paste settle. Store the tube in a cool, dry place and keep the cap closed to prevent drying. Do not use on exposed electrical contacts; observe the product's operating temperature limits.
