Again, thank you.

The PSU fans are 2 wire, only positive and negative no feedback signal indicating the fan RPM.

The large case fans on the front and back of the miners are four wire, do have the feedback for RPM, do require circuit boards for simulation.  I have these circuit boards as part of my plan for the case fans.


My question remains open, does anyone have experience with S17+ Immersion for how to deal with the PSU fans?
