The fans will have a minimum/maximum fan speed percent where the horizontal dotted lines are located in the Fan Curve Editor as shown
here (20/100) and depends on which BIOS you're using..The Primary/Master will allow for zero-fan operation..I think the Secondary/Slave will run the all fans (not just the GPU fan) in low-rpm mode (a minimum of 20%) no matter how low the temps get.
A long time ago I wondered if overclock settings remained after Precision was closed, so I tried it to find out, and I did
PX16 and earlier (with 'Start Up On' enabled) and MSI Afterburner (with 'Apply overclocking at system startup' enabled) will write to the Graphics Driver and apply an OC at Windows Startup when the driver loads, not just after the utilites themselves load and run..PX1/PXOC won't do that.
If you want an overclock to apply at Windows startup without any software being run, install MSI Afterburner, apply your overclock in Precision (or Afterburner), close Precision and open Afterburner and enable 'Apply overclocking at system startup', then close Afterburner and just use Precision from there on out..But don't forget you did that..All that will be lost if you install/reinstall a Grahics Driver.
If you want to have the fans (at least the GPU fan, and maybe the other fans, I don't know) to start at a fixed manual speed, set them in Precision, close Precision, open Afterburner, enable 'Apply overclocking at system startup', close Afterburner..That should probably do it, just like with the clock speeds.
Precision and Afterburner can work together on most things if you know how to do it and become familiar with how they interact with each other, especially the 'Apply overclocking at system startup' button in Afterburner which will write Precision's overclock/fan settings to the Graphics Driver and isn't software dependent.
That should give you something to play with for a while and see what works, or doesn't.

Setting the fans to a static 22% is a dangerous thing to do; because when you start doing something GPU intensive, the card will get hotter and hotter and hotter and the fans will never speed up, because you told them to stay at one speed. It would be better to just leave the fans operating in their default Auto mode controlled by the BIOS or MCU as necessary.
"Run fans without PX1?"
Yeah, they run themself. Just leave them alone instead of doing more harm than good.
True story.
