Highly compressible foam gasket for GPUs, designed to protect electronic components when using liquid metal or other electrically conductive thermal interface materials, while at the same time increasing the lifespan of liquid metal.

The TG GPU Guard is a highly compressible foam gasket for the GPU dies of graphics cards. It protects electronic components when using liquid metal or other electrically conductive thermal interface materials, while also extending the durability of liquid metal. The TG GPU Guard covers the surface-mounted devices (SMDs) next to the GPU and is slightly taller than the GPU die itself. The highly compressible base material has a height of 0.8 mm and can be compressed down to 0.15 mm, easily compensating for height differences of the SMDs.

How it works

When mounting the cooler, the applied pressure fully compresses the foam to bridge the height difference between the PCB and the cooler, ensuring that liquid metal (or other thermal compounds) cannot spread onto other components on the PCB. In addition, the foam gasket prevents oxygen from reaching the liquid metal, which further increases its lifespan. The TG GPU Guard is gallium-resistant.
