Pros & Cons

Pros

  • ✓ Rated >5.15 W/m-K, 62% more conductive than the Series 7 formula
  • ✓ Large 30G syringe covers dozens of CPU and GPU applications
  • ✓ Non-conductive and non-curing, safe if it contacts nearby pins
  • ✓ Wide -50 to 340C operating range for extreme or sustained loads

Cons

  • ✗ High-density paste is thicker and harder to spread than thin compounds
  • ✗ 45% metal-oxide load means careful application around contacts
  • ✗ 30G is far more than a single-CPU reapply needs
  • ✗ No spreader tool or applicator card included in the syringe
