Thermal pad for component cooling

This thermal pad sits between a heat-generating component and its heatsink to improve heat transfer. The silicone-based material fills microscopic gaps and uneven surfaces that would otherwise trap air. It is designed for use on desktop and laptop GPUs, CPUs, LED modules and other electronics requiring a compliant interface.

Builders needing a 12.8 W/mK 0.5mm pad

The pad suits repairs or upgrades where a 120mm square sheet of 0.5mm thickness matches the component stack height. It is not suitable for assemblies that require a thicker or thinner gap filler, nor for applications demanding a higher thermal conductivity rating than 12.8 W/mK.

12.8 W/mK thermal conductivity rating

This figure determines how effectively the pad moves heat across the interface. The material also withstands long-term operating temperatures from -40°C to 200°C and provides electrical insulation with a breakdown voltage above 9.8KV at 1mm thickness.

Questions about this item

What gap thickness does the 0.5 mm pad fill between a heatsink and component?

The pad is 0.5 mm thick and compresses to bridge uneven surfaces and air gaps between the heat source and heatsink.

How do I install the 120x120 mm pad without tearing the silicone sheet?

Cut the 120x120 mm sheet to size, peel the protective film, place it on the clean component, then press the heatsink down evenly so the natural viscosity spreads the pad.

When should I replace the 15 g thermal pad after long-term use?

The non-curing silicone stays pliable from -40 °C to 200 °C; replace it only if the pad dries out, tears, or thermal performance drops after repeated disassembly.
