Arrrrrrrrrrrrrrggggh there be ventilation in your future mateeeeeeee!!
Good News on the 60mm Noctua, The positive wire simply rotted off the circuit board, encased in green fuzz.
Another fan sucumbs to the green corrosion at the wire entry.
But I nipped away at the hub with some side cut wire cutters until I could see well enough to get a soldering iron in there to reattach. I bridged the red and yellow wire entry, the yellow being a rpm signal to the non existent computer mother board. This was unintentional and undesirable, and remedied after the multimeter confirmed my suspicions.
This wire entry is now submerged and encased with curing Amazing Goop. The inside of the Meanwell Power supply had some badly impacted dust in a few nooks and crannies.
The Arctic Cool f12 PWM fan is installed.

I had one of these fail, but it was 11.5 years old and colored differently. the special mounting rubber feet which hold the hub to frame had long broken off and screws and Zipties took over.
Which caused me to buy a newer one half that age, which lasted but a few months before failure, cause not determined or remembered or both.
The original was then reemployed and only failed recently and the one employed today was bought mainly as a backup, and since it had PWM speed control, I might employ that feature. I did add a PWM third wire to the blue when I soldered red and black so the speed control option is still there. It is much quieter than the recently failed unit, due to rubber mounts replacing screws and zipties. It also places more space between it and the silverstone fm121 it is feeding.
Me thinks this extra 5 to 8mm distance betweeen counter rotating fan blades is Mo betta from airflow and perhaps noise perspective. Unfortunately these rubber feet are all too easily broken.
