As you know, AMD Ryzen 5000 processors come soldered to integrated heat spreaders and provide very good thermal conductivity. Therefore, there is no need for delid on CPUs. Users who like to use quality liquid metal, reduce temperatures and take a little risk can choose the way to delid in various processors.
Ryzen 7 5800X3D, one of the first chips to use 3D V-Cache technology, was produced differently from other Ryzen 5000 models. The new processor has an additional layer of L3 cache above the CPU core chip, increasing the risk of cache unit damage during delid. In short, this process is more risky and more difficult.
User @Madness7771 has completely disconnected the IHS on the processor and claims that the 5800X3D no longer rises to high temperatures (90°C). However, workloads and cooling solutions were not mentioned. It also seems that the chip continues to work, although the user does not provide any evidence.
The user also stated that in the Forza Horizon 5 tests, the temperatures dropped by 10 degrees and the frequencies went higher. As you can see from the photos, the CPU with 3D V-Cache is full of capacitors all over and the process of separating the integrated heat spreader should be much more difficult.
