Question Which of these fan configs would you pick to improve 7800x3D cooling?

All fans are 120mm Thermalright TL-C12CW-S, same as the ones included in my PA 120SE cooler. Case is a 5000D Airflow.

I have 10 of those fans, but currently I'm only using 7 as my setup is Option A. The problem is the 7800x3D is getting a bit warm for my liking: while gaming stays around 75-80ºC but during heavy cpu tasks (decompressing files or Cinebench R20 all cores) is going up to 88-89ºC (no thermal throttling).

I know the 7800x3D can get hot, but I wonder if my current setup could be improved with Option B. This is, removing the front top fan (exhaust) to allow all the frontal intakes to reach the CPU.

Option C is probably a terrible idea, as opposite fans being so close to each other, could decrease their performance (basically what I think is happening with my current setup Option A, between the front top fan (exhaust) and the frontal top fan (intake) (what a wording mess)).

Option D could be another alternative adding fans from the side of the case as I already have them around, but I think then my PC will become a super dust magnet.

Thoughts? Any other option? Thanks!

None of them. The moment a roof fan is positioned in front of a tower air cooler, when the goal is to maximize cpu cooling, you've failed. Some of the air coming in from the front/side is going to get pulled out before it gets to the front fan of the cooler.
Extra fans up top are to the benefit of the gpu cooler, which most of them dump the gpu's waste heat inside the PC. The idea is to remove the heat from the largest heating device as fast as possible, at the cost of a little higher cpu temperatures.

The extra Z-height caused by the Vcache makes this chip harder to cool compared to other Ryzen 7000s; moving the heat from the die through the IHS is harder... and all these case fans doesn't fix an issue that's under the hood.

Ok ty, what would you suggest then to improve CPU thermals? An AIO?
