Hi all - need some help on figuring out how to keep the power supply fan running at 100% when the machine is either completely shutdown or in sleep mode. Has anyone else dealt with this or know of a solution?
I can hear my deskop fan running all night long

You can unplug your PC after you log out of Windows as a workaround.
If there is no power the fan will not run.
Have you updated the BIOS to the most recent one (01.06.04 Rev. A Aug 6, 2023) available?

Try disabling fast startup.
