Pros & Cons

Pros

✓ 12.5 W/mK thermal conductivity, top-tier for delidded chips and overclocking
✓ 5.55 g / 1.5 ml is enough for a dozen-plus CPU or GPU applications
✓ Kit bundles 2 applicators and 2 spatulas for even, repeatable spreads
✓ 4 CPU cleaning pads included, so no separate isopropyl prep needed

Cons

✗ 39.99 USD is steep next to single-syringe pastes of the same volume
✗ Rated not to dry out to 80 C; sustained hotter loads may shorten life
✗ Non-curing paste, so expect periodic reapplication on hot-running rigs
✗ Bulk 5.55 g set is overkill if you only plan one CPU reseat
