I've had this problem come and go since I bought this setup a few yrs back and I've never been able to pinpoint it, Randomly when the PC is shutdown, the fan kick in full bore and stay on until I flip the main power switch, I have tried turning off C states in the bios, which is updated to the latest, I have disabled any hibernate or sleep options on the PC, The fans are Corsair LL120 RGB Black Triple Fan Kit with Lighting Node PRO connected through NZXT Internal USB Hub, I don't know a setting to make the power turn off to that when its shut down, could be the problem? Any idea's will help, thanks.

Mod edit: Latest Chipset, Windows updates etc too.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS: version(not edition) of OS if on Windows 10
Monitor:

For the sake of relevance, you should include the BIOS version for your motherboard and the age of the PSU used in the build. Just out of curiosity, did you try removing the USB hub(and everything it's connected to) entirely and seen if the issue persists?

I haven't unplugged the USB hub because I'm not 100% sure what else is being powered by it, I don't want something to over heat etc, and here is the build.
