Gap-filling pad for desktop and laptop heatsinks

This 120x120mm silicone pad sits between a GPU, CPU or LED module and its cooler to replace air gaps with a 12.8 W/mK thermal path. The 1.5mm thickness and 15g weight suit stock cooler clearances on mainstream graphics cards and notebooks. Non-conductive and non-corrosive chemistry makes it safe for direct die contact.

Softness range limits clamping pressure

Shore 00 hardness spans 30 to 55 so the pad compresses under light mounting force but will not flow like grease. Continuous operating temperature is rated from -40°C to 200°C with a short-term peak of 400°C. Breakdown voltage exceeds 9.8 kV at 1mm, providing electrical isolation across the interface.

Peel-and-place install with reusable viscosity

Natural tack holds the sheet in position while you align the heatsink, and the pad can be lifted and repositioned if the first seat is uneven. Density of 3.1 g/cc means it resists pump-out over thermal cycles. Installers must ensure the 1.5mm thickness matches the specific gap; thinner or thicker stacks will not be compensated by this single sheet.

Questions about this item

Which thickness should I pick for my GPU or CPU gap?

The pad is 1.5 mm thick, a common size for many stock cooler clearances; measure your gap before ordering.

What does 12.8 W/mK mean for actual temperatures?

It indicates high thermal conductivity for a silicone pad, so heat moves from die to heatsink more efficiently than standard pads, lowering junction temperatures under load.

Is the pad electrically safe and what voltage can it withstand?

It is non-conductive with a breakdown voltage above 9.8 kV per mm, providing reliable insulation for typical low-voltage PC components.
