What this product is and who it is for

Arctic Silver 5 is a high-density thermal compound made with 99.9% pure silver particles in three unique shapes and sizes. The 3.5g tube provides enough material for 15 to 25 small CPU cores or 6 to 10 large CPU cores. It is intended for system builders and enthusiasts who need reliable heat transfer between modern high-power CPUs and high-performance heatsinks or water-cooling solutions. The OEM packaging includes only the product itself without documentation or bundled accessories.

Build quality and daily handling

The compound contains over 88% thermally conductive filler by weight including micronized silver, sub-micron zinc oxide, aluminum oxide and boron nitride particles with an average particle size under 0.49 micron. Its controlled triple-phase viscosity allows precise application and stable long-term performance across an operating range of -50 to 130 Celsius, with extended peak limits beyond 180 Celsius. The syringe-style tube enables controlled dispensing directly onto the heat spreader without separate tools or applicators.

What to check on your existing setup

Verify that your CPU cooler or water block mounting hardware provides even pressure across the integrated heat spreader for optimal particle-to-particle contact. Ensure the mating surfaces are clean and free of old compound residue before applying a thin layer. This product is not electrically conductive, but avoid bridging adjacent surface-mount components on exposed die packages. Confirm the 3.5g volume matches your expected number of applications or future maintenance needs.

商品問答

What temperatures can Arctic Silver 5 handle long-term?

The compound is rated for continuous operation between -50 and 130 Celsius, with peak tolerance above 180 Celsius.

How many CPU applications does a 3.5g tube cover?

One tube covers 15 to 25 small CPU cores, 6 to 10 large CPU cores, or 2 to 5 heat plates.

What is the correct way to apply Arctic Silver 5?

Place a small drop in the centre of the CPU and let the heatsink pressure spread it evenly; do not pre-spread with a card or finger.
