The Thermal Grizzly AM5 High Performance Heatspreader in detail
The AM5 High Performance Heatspreader is an upgrade heatspreader for AMDs Ryzen 7000 processors. The nickel-plated copper heat spreader features a 240 percent larger, diamond-milled precision surface. This larger surface area compared to the original heat spreader enables maximum heat dissipation for air and water coolers, while precision milling ensures extremely low surface roughness for best contact with the heat sink.

The nickel-plated surface of the AM5 High Performance Heatspreader is compatible with traditional thermal pastes and gallium-based liquid metals. The nickel forms a barrier layer between the liquid metal and the copper cooler, so that liquid metal does not diffuse into the copper and alloying is minimized. This means that repeated application of liquid metal is usually not necessary.

For a system that is as maintenance-free as possible, a KryoSheet graphene thermal pad can be used as a thermal interface between the CPU and the AM5 High Performance Heatspreader. Since KryoSheet pads are electrically conductive, a cover is included to protect the electronic components on the CPU package.
