  • 18 W/mK thermal conductivity moves heat fast from chip to heatsink
  • 5 mm thickness compresses to fill uneven gaps
  • Non-conductive silicone insulates electrically while transferring heat
  • Operates from -40 °C to 200 °C without melting or curing
  • 30 Shore hardness stays soft and reusable through repeated installs

Thermal pad for CPU and GPU cooling

The UPSIREN OEM thermal pad measures 100x100mm with a .5mm thickness and weighs 23g. It is designed to fill gaps between chips and heatsinks in laptops, desktops and other electronics. The silicone material is non-conductive, non-corrosive and non-toxic for safe handling.

18W/mK conductivity with 16W/mK operational rating

The pad delivers a thermal conductivity of 18W/mK while the supplier notes a 16W/mK rating in the detailed description. It operates reliably from -40 to 200 C without melting. The 30-degree hardness allows compression for close chip contact but may not suit applications requiring thicker or multiple pads.

Soft silicone with natural viscosity for reuse

The pad's natural viscosity makes it easy to assemble and reusable during maintenance. It is electrically insulating, anti-static, wear-resistant and fire-retardant. The material resists corrosion and produces no odour, protecting metal surfaces across LED, automotive, power and industrial applications.

Questions about this item

Will the .5mm pad sit flat on my existing heatsink without lifting?

The pad measures 100x100mm and is .5mm thick, so it will conform to the heatsink surface without adding noticeable height.

How can I confirm the pad is conducting heat properly after installation?

Monitor component temperatures under load; the pad is rated for 18W/mk conductivity and operates from -40 to 200 C, so temperatures should stabilise within expected ranges.

Does the package contain only the single pad or are extra sheets included?

The listing specifies one pad weighing 23g at 100x100x.5mm; no additional pads, tools or adhesive are mentioned.
