Details
Thermal Grizzly's TG GPU Guard as a universal 100 x 100 x 0.8 mm foam pad, cut by you into gaskets that sit around the GPU dies of graphics cards when you run liquid metal. For a GeForce RTX 5090, RTX 5080 or RTX 4090, the NVIDIA GPU Set comes ready cut.

- Material
- Gallium-resistant foam, red
- Height
- 0.8 mm, compresses down to 0.15 mm
What it does
The gasket is a highly compressible foam frame for the GPU die. It covers the surface-mounted devices (SMDs) next to the GPU and protects those electronic components when using liquid metal, such as Conductonaut, or other electrically conductive thermal interface materials. The base material has a height of 0.8 mm, slightly taller than the GPU die itself, and can be compressed to 0.15 mm, easily compensating for height differences of the SMDs. The foam is gallium-resistant.
How it works
When mounting the cooler, the applied pressure fully compresses the foam. It can then bridge the height difference between the PCB and the cooler while ensuring that liquid metal (or other thermal compounds) cannot spread onto other components on the PCB. In addition, the gasket also works for the liquid metal itself, extending its durability: the foam prevents oxygen from reaching it, which further increases its lifespan.
Cutting the pad
The universal variant consists of one pad that can be individually cut to size. Depending on the size of the GPU dies, one pad may be sufficient for multiple GPUs. When cutting the universal version, please observe the following points:
- Measure the GPU die and mark its outline on the foam with a permanent marker. The cutout should be 1-2 mm larger around the die.
- Whenever possible, use a sharp scalpel on a suitable cutting surface.
- Work carefully and patiently.
- Cut the opening for the GPU first and the outer edge last.
Notes
- Apply the gasket according to the instructions before applying liquid metal to the GPU and cooler.
- Each cut gasket is used once: it is not reusable.
- Not for use with CPUs!
