Thermal Grizzly Ryzen 7000 Lapping Tool

The AM5 Lapping Tool was developed for grinding the heatspreaders of AMD's AM5 processor series. The tolerances of the AM5 Lapping Tool allow the heatspreader to be gradually ground down by 0.4 mm, up to a total height of 1.6 mm. When using the normal AMD mounting frame (SAM), a maximum lapping of 1.0 mm is provided until the middle steps are reached.

A further 0.6 mm is only possible if the CPU is mounted with a suitable AM5 Contact Frame, for example (product to follow shortly). The steps of the AM5 lapping tool are diamond-milled to achieve a high level of transparency. This makes it possible to see which steps have already been reached and which have not when grinding.

Lower temperatures thanks to grinding the heatspreader
The US content creator and tech YouTuber "JayzTwoCents" was able to achieve up to 5 degrees Celsius lower temperatures with slightly higher boost clocks of all cores with a Ryzen 9 7950X using a 360 mm AiO by grinding the heatspreader. In combination with the Kryonaut Extreme thermal paste, temperatures were even 10 degrees Celsius lower (compared to standard thermal paste).

Even with a moderate overclocking of all cores of the Ryzen 9 7950X to 5.4 GHz, the test system remained 4 degrees Celsius below the temperature limit of 95 °C.

These temperature improvements due to the grinding of the heatspreader are partly due to the heatspreaders of the AM5 platform. The heatspreaders introduced with Ryzen 7000 are thicker than the AM4 heatspreaders so that AM4-compatible CPU coolers also remain compatible with the AM5 platform. In addition, the surface area of the Ryzen 7000 heatspreader is significantly smaller at approx. 910 mm² compared to AM4 at 1,300 mm².

Note on compatibility with AM5 mainboards
Please note that grinding the CPU will invalidate the warranty. To ensure the largest possible contact surface between the IHS and the base plate of the CPU cooler, the latter should also be ground.
