Pros & Cons

Pros

  • ✓ 30 pads in one box: 6 each of 0.5, 1, 1.5, 2 and 3 mm thickness
  • ✓ 2.0 W/m.k silicone claimed to cut peak temps 5-10C without a heatsink
  • ✓ Soft 40 Shore compound conforms to uneven VRM and NAND surfaces
  • ✓ Cuttable, stackable and reusable, so odd gap sizes are covered
  • ✓ Rated -40 to 200C with 5 KV/mm breakdown voltage and RoHS compliance

Cons

  • ✗ 2.0 W/m.k lags the 6-12 W/m.k pads used for high-wattage GPU memory
  • ✗ Fixed 67x20 mm sheets need trimming for most laptop and SSD jobs
  • ✗ Self-adhesive face can leave residue that has to be cleaned off later
  • ✗ Pads get stickier once heated, making later teardowns messier
