Arctic Silver 5 12g thermal compound

Arctic Silver 5 is a high-density polysynthetic silver thermal compound designed for reliable heat transfer between modern high-power CPUs and high-performance heatsinks or water-cooling solutions. The 12-gram tube provides enough material for at least 50 small CPU cores, 20 large CPU cores, or 7 to 15 heat plates. It is suited for system builders who do not require bundled accessories or documentation.

Sustained load thermal behaviour

The compound operates continuously between minus 50 and 130 degrees Celsius, with peak tolerance exceeding 180 degrees Celsius. Its controlled triple-phase viscosity and over 88 percent thermally conductive filler by weight maintain stable particle-to-particle contact during prolonged high-power operation. Average particle size below 0.49 micron supports consistent thermal transfer over time.

Compatibility checks before ordering

Verify that your CPU and cooler mounting hardware allows standard thermal paste application without pre-applied pads or phase-change material that must be removed. Ensure the surface area to be covered matches the stated coverage estimates for core count or heat plate quantity. The OEM packaging includes only the compound tube with no applicator or cleaning supplies.

Questions about this item

Will the 99.9% pure silver compound dry out or pump out after months of continuous operation at 130 °C?

The compound is rated for long-term use up to 130 °C and peak exposure beyond 180 °C without drying or pumping out.

What tools or accessories must I already have to apply this 12 g tube of Arctic Silver 5?

You need only a clean lint-free cloth and isopropyl alcohol to prepare the surfaces; no applicator or spreader is included in the OEM package.

Can I use this paste on an older CPU with a large heat spreader without changing my existing cooler mounting hardware?

The 12 g tube covers up to 20 large CPU cores and works with any standard heatsink or water-block mounting system already installed.
