GPU Guard Gasket for RTX 4090 5080 5090

The Thermal Grizzly TG-GG-01 is a highly compressible foam gasket set designed for GPU dies on GeForce RTX 4090 5080 and 5090 graphics cards. It protects surrounding surface-mounted devices when using liquid metal or other electrically conductive thermal interface materials. The package contains nine pieces covering all three supported models.

Upgrade from bare die application

Builders who currently apply liquid metal directly to the die without a barrier gain protection against short circuits from spills onto nearby components. The jump is worth it when switching to conductive compounds or when seeking longer liquid metal durability through oxygen isolation. The gasket compresses from 0.8 mm down to 0.15 mm under mounting pressure to bridge height differences.

Nine gaskets covering three dies

The set includes three gaskets each for RTX 4090 5080 and 5090 dies providing enough pieces for multiple installations or replacements. It comfortably handles liquid metal applications on supported GPUs while preventing compound spread and oxidation. It runs out when used on unsupported GPUs or CPUs as the product is not reusable and not designed for processor dies.

Questions about this item

How thick is the foam gasket before and after compression?

The gasket starts at 0.8 mm and compresses down to 0.15 mm to match SMD height differences.

What does the transfer film do during installation?

It holds each gasket in position so you can place it on the die before applying liquid metal.

When do the gaskets need to be replaced?

They are single-use; install a fresh set whenever you reapply liquid metal.
