GPU die protection gasket

The Thermal Grizzly TG GPU Guard is a compressible foam gasket designed to shield GPU dies and adjacent surface-mounted components when using electrically conductive thermal interface materials such as liquid metal. It prevents short circuits and extends the lifespan of the liquid metal by limiting oxygen exposure. Builders applying liquid metal to graphics cards will find this essential for safe installation.

Simple cut-to-fit installation

The universal 100 × 100 mm pad is trimmed with a scalpel to match the specific GPU die layout, and instructions guide the measuring and cutting process. The foam compresses from 0.8 mm down to 0.15 mm under cooler mounting pressure, automatically bridging height differences between the die and surrounding components. The gasket is not reusable and must be replaced if the cooler is removed, and it is explicitly not intended for CPU applications.

Covers multiple GPU sizes

A single 100 × 100 mm sheet provides enough material for several installations across different graphics card models. The foam's gallium-resistant composition ensures it does not degrade during long-term contact with liquid metal. Users requiring a pre-cut shape for a specific card or those installing on CPUs will need a different solution.

Questions about this item

How do I verify the gasket has compressed correctly after installing the cooler?

The 0.8 mm foam compresses to 0.15 mm under mounting pressure, fully bridging the height gap between the GPU die, SMDs and heatsink so liquid metal cannot spread onto the PCB.

What comes in the package and do I need any extra tools to fit it?

One 100 × 100 mm universal pad is supplied; you must cut it to shape yourself using a scalpel or sharp knife following the included measuring and cutting instructions.

Which version should I choose for my graphics card?

Only the universal 100 × 100 × 0.8 mm variant is offered; trim it to match your specific GPU die and surrounding SMD layout.
