Pros & Cons

Pros

  • ✓ 99.9% pure micronized silver maximizes CPU-to-heatsink thermal conductivity
  • ✓ Cuts CPU core temperatures up to 50°F versus standard silicone pastes
  • ✓ Silicone-free formula won't separate, run, migrate, or bleed over time
  • ✓ Three silver particle shapes boost particle-to-particle contact area

Cons

  • ✗ Electrically capacitive; spillover onto pins or traces risks shorts
  • ✗ Needs a long break-in cure to reach peak thermal performance
  • ✗ Thick viscosity spreads less easily than lighter modern pastes
  • ✗ Older formula; newer non-conductive compounds now rival its numbers

Manufacturer description

Arctic Silver 5 High-Density Polysynthetic Silver Thermal Compound 3.5g AS5-3.5G Arctic Silver 5 premium thermal compound, with 99.9% pure micronized silver, is specifically designed to maximize the thermal conductivity between today's high-powered processors and high-performance cooling assemblies. Arctic Silver 5 uses three unique shapes and sizes of near-pure silver particles to maximize particle-to-particle contact area and thermal transfer. It can reduce CPU core temperatures by up to 50°F over standard silicone thermal pastes. Controlled triple phase viscosity allows Arctic Silver 5 to…
