Unique-Bargains Thermal Pads 100mm x 100mm x 2mm Blue Pack of 2

Thermal pads for uneven gaps

These 100 mm square silicone pads sit between a heatsink and a component to fill air gaps and improve heat transfer. Each sheet is 2 mm thick and rated at 1.5 w/m-K conductivity. The pack contains two blue pads that are soft enough to compress and cushion the mating surfaces. They suit builders who need a tidy, pre-cut alternative to paste for memory modules, VRM arrays or small chipsets.

Replaces messy paste on flat interfaces

Unlike thermal grease, these pads leave no residue and cannot pump out over time. The jump is worth it when the contact faces are uneven or when a component sits slightly lower than the heatsink base, because the 2 mm thickness bridges the gap without excessive pressure. They are not for buyers who need the absolute lowest thermal resistance on a perfectly flat CPU die, where a thin layer of quality paste still outperforms a 2 mm silicone layer.

Limited by 1.5 w/m-K conductivity

The material withstands temperatures from 50 to 200 °C, so it survives normal operating ranges but cannot match high-end pads rated above 5 w/m-K. At 2 mm thick the thermal path is longer than a typical paste line, which adds resistance on high-power devices. Installers must clean surfaces, peel both protective films and apply even pressure; the pads cannot be reused once compressed.
