Premium Thermal Compound

The ARCTIC MX-7 is a high-performance thermal paste designed for CPUs, GPUs, laptops and consoles. Its dense, highly viscous consistency comes from a high filler content that ensures exceptional heat transfer between the die and cooler. The compound is electrically non-conductive and non-capacitive, eliminating any risk of short circuits on sensitive components. It is supplied in a 3.5g syringe for precise application.

Upgrade From Standard Pastes

This compound replaces basic or aged thermal interfaces that have dried out or lost efficiency over repeated thermal cycles. The jump is worth it when your current paste shows high temperatures, pump-out or bleeding after extended use. MX-7 offers long-term stability with high cohesion that prevents degradation, removing the need for frequent reapplication. Its optimised formula maintains consistent performance throughout the hardware lifespan.

Check Cooler Pressure Before Ordering

MX-7 cannot be spread manually with a spatula due to its special texture; it relies entirely on mounting pressure to distribute naturally. Verify that your cooler installation provides even, firm contact across the die surface to form a thin bond line without trapping air bubbles. The syringe contains 3.5g net weight, sufficient for multiple applications on standard desktop processors. Ensure surfaces are clean using a dedicated cleaner like MX Cleaner for optimal results.

Questions about this item

Will the 3.5g syringe cover a standard CPU heat spreader?

Yes, 3.5g is enough for multiple CPU applications; the dense paste spreads thin under cooler pressure.

Since MX-7 cannot be spread manually, how do I apply it correctly?

Place a small dot or line on the centre of the heat spreader, then mount the cooler — pressure distributes the paste evenly without air bubbles.

Does MX-7 dry out or need reapplication after a few years?

High cohesion prevents pump-out and dry-out through repeated thermal cycles, so reapplication is not needed for a long time.
