The DeepCool AK620 Digital cooler is designed to support processors with high thermal power, but it's not clear whether it's sufficient for an AMD Ryzen 7 9800X 3D. However, the DeepCool AK620 Digital is capable of handling up to 260W of thermal power, which could be enough for a processor like the Ryzen 7 9800X 3D, which has a TDP of 120W. To ensure optimum cooling, it is advisable to check actual performance in practical tests.
