UPSIREN OEM 21W/mK Thermal Pad

This UPSIREN OEM thermal pad measures 100x100x1.5mm and weighs 23g. It provides a thermal conductivity of 21W/mK for CPU, GPU, laptop heatsink or LED cooler applications. The silicone pad is non-conductive and non-corrosive. It suits builders who need a single reusable interface sheet.

Installation and common issues

The pad has a hardness of 30 degrees, making it soft and compressible for easy assembly. Natural viscosity allows it to fit closely to the chip surface and be reused. It is non-curing and non-toxic, so it will not dry out or damage components. Users who need a pre-applied paste or a thinner gap filler should look elsewhere.

Sustained load behaviour

Rated for long-term operation from -40 to 200°C, the pad will not melt under continuous high temperatures. It maintains insulation, anti-static and fire-retardant properties during extended use. The material resists wear, compression set and corrosion over time. Buyers requiring a liquid metal compound for extreme overclocking cannot use this pad.
