The fan on the psu only spins when needed (when it gets hot). It's controlled by the psu, nothing you can do to change the fan settings.
I turned on my Aurora R6 the other day. It has the less-than-ideal 460w PSU (power supply unit). Now when my pc froze it crashed and I had it set to not auto-restart so I can see what happened. There was no error message. I then rebooted and It kept flashing 1 yellow, bios or rom issue. I tested the PSU because I've suspected for awhile that it was going downhill. The button turns green but the fan doesn't spin. Is the fan supposed to kick-up when the button is pressed? The fan will kick on when I stress the system through OCCT. Should I be looking into getting a aftermarket PSU ASAP? If so I was eyeing Corsair X series 750 watt 80 plus rated supply should mine fail. I think my system has been stressing the psu too much since I had to replace the rx480 that came stock with an XFX 580. Thank you.
