Here's the Z590 test bench with the 5333Mhz kit. And you can see only a single 140mm fan downfiring onto the Noctua heatsink and not offering much airflow to the 5333 kit, although it is an open air build so the room AC cools things down.
This build is where I placed a 120mm Noctua over the 5333 kit at the 5866Mhz CL21 CPU 5.1Ghz profile.
You should not need a dedicated RAM fan for the 5333 and the 5600 profiles.
