Pros & Cons

Pros

  • ✓ 14.3 W/m.k rated conductivity, aimed at overclocked CPU and GPU loads
  • ✓ Non-conductive, metal-free formula won't short pins if it spreads off-die
  • ✓ Rated from -250C to +300C, so cold-boot and sustained load both stay in spec
  • ✓ Thermal resistance under 0.0028 for a fast heat path into the cooler
  • ✓ Needle applicator plus included spatula for controlled dots and spreading

Cons

  • ✗ 2g syringe covers only a few CPU mounts before a refill
  • ✗ Manufacturer spec sheet only, no independent lab data for the 14.3 W/m.k claim
  • ✗ Non-metallic pastes generally trail liquid metal on delidded or extreme setups
  • ✗ No stated cure time or reapplication interval for the durability claim
