ARCTIC COOLING Arctic Silver 5 12g thermal paste

Premium silver thermal compound

Arctic Silver 5 uses 99.9% pure micronized silver in three particle shapes to maximize contact area and thermal transfer between high-powered processors and performance coolers. The high-density formula contains over 88% thermally conductive filler by weight including sub-micron zinc oxide, aluminum oxide and boron nitride for long-term stability. Controlled triple-phase viscosity allows the compound to fill microscopic surface valleys over time.

Simple application for CPU and GPU builds

The 12-gram tube provides enough compound for multiple installations across small and large processor cores or heat plates. A 3.5-gram reference amount covers 15 to 25 small cores, 6 to 10 large cores or 2 to 5 heat plates at a 0.003-inch layer thickness. Average particle size below 0.49 micron ensures even spread without excessive pressure during cooler mounting.

Ideal for enthusiasts seeking measurable

Builders who want up to 12°C lower full-load core temperatures versus standard pastes will benefit from the silver-rich formulation. Users needing electrically non-conductive paste or ceramic-only compounds should look elsewhere, as the high silver content makes Arctic Silver 5 capacitive and unsuitable for applications where bridged traces are a risk.
