Thermal Grizzly GPU Guard – 100 x 100 x 0.8mm

The TG GPU Guard is a highly compressible foam gasket designed for the graphics chips (GPUs) of graphics cards. It protects electronic components when using liquid metal or other electrically conductive thermal interface materials and simultaneously extends the lifespan of the liquid metal. The TG GPU Guard covers the surface-mounted devices (SMDs) next to the graphics chip and is slightly higher than the graphics chip 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.

When the cooler is mounted, the pressing force fully fills the height difference between the PCB and the cooler with the foam gasket, preventing liquid metals (or other thermal pastes) from running onto other components on the PCB. Additionally, the foam gasket prevents oxygen from reaching the liquid metal, which increases its durability. The TG GPU Guard is gallium-resistant.
