Grey rectangular silicone thermal pad 85x45x3.0mm

EN-Labs

EN-Labs High Performance 16.8 W/mK Thermal Pad 85x45x3.0mm

SKU CH-Z5GX-7ARED

Non-conductive silicone pad measuring 85 x 45 x 3.0 mm with 16.8 W/mK conductivity for CPU, GPU and heatsink gaps

  • High 16.8 W/mK conductivity moves heat fast
  • Non-conductive silicone prevents short circuits on GPUs and CPUs
  • 85 × 45 × 3.0 mm pad cuts to fit any gap
  • Soft 30–50 Shore C hardness conforms to uneven surfaces
  • >10 kV breakdown voltage insulates high-voltage components

Product identity and purpose

This EN-Labs thermal pad measures 85 by 45 by 3.0 millimetres and delivers 16.8 W/mK conductivity. The non-conductive silicone sheet suits laptops, GPUs, CPUs, LED coolers and assorted electronics where a gap-filling interface is preferred over paste.

Thermals, noise and power in normal use

The pad transfers heat across its grey silicone body without electrical conduction, rated above 10 KV breakdown voltage. Zero moving parts mean silent operation and no power draw, while 3.6 g/cc density and 30 to 50 Shore C hardness keep the interface stable during typical workloads.

Behaviour under sustained load

The material maintains its thermal path during extended sessions because it does not pump out or dry like grease. Users can trim the 85 by 45 millimetre sheet to exact shapes, ensuring consistent contact pressure and steady temperatures over long periods.

Questions about this item

How do I install the 85x45x3.0mm thermal pad and what step do people get wrong?

Cut the pad to size, peel both protective films, place it between the component and heatsink, then apply even pressure; the common mistake is leaving one film on or trapping air bubbles.

What maintenance or replacement will the 16.8 W/mK silicone pad need later?

The non-conductive silicone pad does not dry out like paste; inspect it when you reseat the cooler and replace it if it shows compression set, tearing, or reduced thickness.

What limit appears first on the 3.0mm pad under sustained load?

The 3.0mm thickness and 30-50 Shore C hardness set the minimum gap it can fill; if the mating surfaces separate further, thermal resistance rises before the 16.8 W/mK conductivity becomes the bottleneck.
