Pros & Cons

Pros

  • ✓ 12 W/mK thermal conductivity rating, per the manufacturer
  • ✓ Rated for -40C to 200C without melting
  • ✓ 100x100mm sheet cuts to fit VRAM, SSD controllers, or VRMs
  • ✓ Electrically insulating and anti-static, safe against exposed traces

Cons

  • ✗ Only 0.5mm thick; too thin for gaps that need 1mm or thicker pads
  • ✗ 12 W/mK is a manufacturer claim with no independent test data listed
  • ✗ One 100x100mm sheet; a full GPU repad may need more
  • ✗ No compression or hardness spec to judge fit under clamping force

Manufacturer description

The AIYUNNI Thermal Pad is a 100x100x0.5mm silicone sheet with a manufacturer-rated thermal conductivity of 12 W/mK. It fills the air gap between hot components and a heat sink or metal case. Use it on GPU memory chips, SSD controllers, VRMs, LED boards, set-top boxes, or a retro PC or console you are refurbishing. The pad is soft and flexible, so it presses into uneven surfaces where thermal paste would squeeze out or dry up. You can cut the single 100x100mm sheet with scissors or a hobby knife to fit each chip, so one sheet covers several small components. AIYUNNI rates the material for…

Frequently Asked Questions

Is a 0.5mm thermal pad thick enough for my GPU VRAM?

Only if the original pads were 0.5mm. Many cards use thicker pads on memory and VRMs. Measure the old pads or check your card's teardown documentation. A pad that is too thin leaves an air gap and makes temperatures worse.

What is the thermal conductivity of the AIYUNNI thermal pad?

AIYUNNI rates it at 12 W/mK. The listing does not include independent lab test results, so treat this as the manufacturer's spec.

Can I cut the pad into smaller pieces?

Yes. The 100x100x0.5mm sheet can be cut to any shape, so one sheet can cover several memory chips, an SSD controller, or small ICs.

Is the pad electrically conductive?

No. The listing describes the silicone as insulating and anti-static, and says contact with electrical traces will not cause damage.
