- 100 mm square pad fits many heatsinks
- Simple three-step installation: clean, peel, place
Thermal pad for component gaps
This 100 mm by 100 mm by 3 mm silicone pad fills uneven surfaces between a heatsink and a component to improve thermal transfer. It suits builders who need a compliant gap filler with a thermal conductivity of 1.5 w/m-K and a withstand range of 50 to 200 degrees Celsius. The blue colour aids visual identification during assembly. It is not for buyers who need a liquid compound or a thinner interface material.
Single pad in the package
The bundle contains one thermal conductive pad with protective films on both sides. No additional tools, cleaning wipes or mounting hardware are supplied, so the installer must provide isopropyl alcohol and a lint-free cloth for surface preparation. The lack of extra accessories keeps the kit minimal but requires the user to plan the cleaning step beforehand.
Peel-and-place installation
Installation follows three steps: clean the mating surfaces, remove the protective films, then position the pad where needed. The low-hardness silicone compresses easily, which helps it conform to irregular surfaces without excessive pressure. The main risk is trapping dust or leaving film residue on the pad, both of which reduce thermal performance. Trimming the 100 mm square to a smaller shape is possible with scissors but demands care to avoid tearing the soft material.

Questions about this item
Will the 3 mm silicone pad need replacement after long-term use?
The pad is designed to withstand temperatures from 50 to 200 and retains its thermal conductivity of 1.5 w/m-K, so it typically lasts the life of the heatsink without needing replacement.
What limits continuous heat transfer with the 1.5 w/m-K conductivity?
The 1.5 w/m-K rating is the primary limit; sustained loads that exceed the pad’s ability to move heat across the 100 mm square area will cause temperatures to rise.
Does the pad generate noise or extra heat when running all day?
The silicone pad has no moving parts and produces no noise; it simply conducts heat up to its 1.5 w/m-K rating while staying within the 50 to 200 withstand range.
