Unique-Bargains Thermal Pad 100x100x4mm Blue 1.5 w/m-K

SKU CH-B7YC-QJ99H

Blue silicone thermal pad measuring 100 × 100 × 4 mm with 1.5 W/m-K conductivity for heatsink gap filling

  • Improves heat transfer with 1.5 w/m-K conductivity
  • Fills gaps between uneven surfaces for better cooling contact
  • Operates reliably from 50 to 200 degrees Celsius
  • Soft silicone cushions components while maintaining compression
  • Ready-to-install 100 mm square pad with protective film

Product Identity

Unique-Bargains Thermal Pad is a soft silicone sheet measuring 100mm by 100mm by 4mm with a thermal conductivity of 1.5 w/m-K. It is designed to fill gaps between a heatsink and components such as CPUs, GPUs or memory modules to improve heat transfer. The blue pad suits builders who need a compliant interface material for uneven surfaces. It is not intended for buyers who require higher conductivity pads or thinner profiles for tight clearances.

Installation Notes

Installation requires cleaning the component surface, removing the protective film and placing the pad in position. The low-hardness silicone compresses easily to bridge irregularities and provides damping. The main risk is selecting an incorrect thickness or size for the specific gap, which can reduce contact pressure or leave voids. No tools or curing time are needed, but the pad must not be reused once compressed.

Practical Limits

The pad operates within a withstand temperature range of 50 to 200. Its fixed 4mm thickness and 100mm square dimensions limit use to gaps that match those measurements. Thermal conductivity of 1.5 w/m-K is modest compared to premium compounds, so the pad suits moderate heat loads rather than high-power devices. It cannot be cut reliably without affecting compression uniformity.

Questions about this item

How can I verify the thermal pad is making proper contact after installation?

After placing the pad between the heatsink and component, check that the silicone has compressed evenly across the 100mm x 100mm surface with no visible gaps or air pockets.

What comes in the package and is anything else needed for installation?

The box contains one 100mm x 100mm x 4mm blue silicone thermal pad with 1.5 w/m-K conductivity. You only need isopropyl alcohol or a similar cleaner to prepare the component surfaces before applying the pad.

Which thickness and conductivity should I select for my GPU or CPU cooler gap?

Choose this 4mm thick, 1.5 w/m-K pad when your heatsink-to-component gap measures approximately 4mm; the pad withstands 50 to 200 degrees Celsius and suits larger chipsets or VRM arrays needing a 100mm square filler.
