Gap-Filling Thermal Pad

The Lirealar 120x120mm thermal pad delivers 12.8 W/mK conductivity in a 2.5mm thick sheet. Grey silicone material compresses to bridge uneven surfaces between heat sources and heatsinks. Non-conductive insulation prevents electrical shorts across CPU, GPU or LED cooler components. Supplied as a single 150g pad sized 120x120mm.

Builders Needing High-Conductivity Gap Filler

Suits desktop and laptop repairs where a 2.5mm thickness matches the component stack height. Buyers who need a thinner or thicker interface layer should look at alternative pad heights. Not for applications requiring liquid metal or phase-change compounds instead of a solid silicone sheet.

Simple Press-Fit Installation

Natural viscosity holds the pad in place during assembly without adhesive. Cut to shape if the target die is smaller than 120mm. Avoid stretching the material; over-compression beyond the 30-55 Shore C range reduces long-term performance. Reusable if removed carefully without tearing.

Fragen zu diesem Artikel

What minimum heatsink surface is required for the 120x120mm pad to cover the CPU or GPU die?

The pad measures 120 by 120 millimetres and is 2.5 millimetres thick, so the heatsink contact area must be at least that large to avoid overhang.

Will the 12.8 W/mK pad work if I reuse my existing cooler that has uneven mounting pressure?

Yes, the pad compresses between 30 and 55 Shore C and its natural viscosity fills gaps on uneven surfaces, compensating for irregular pressure across older coolers.

How can I verify the pad is seated correctly after installation?

After mounting, check that the pad has spread evenly without air pockets, that temperatures drop under load within the -40 to 200 Celsius operating range, and that no electrical shorts occur thanks to the >9.8 kV breakdown voltage.
