So i have a Z370 I7 PROFESSIONAL GAMING, and connected 3 fans to the headers on the board, when pc is shut down, the fans still get power to them, whats weird is that months ago when i had other fans connected, this didnt happen, these are rgb ll 120 fans from corsair . How do i cut off power to them in the bios ? the S5 deep sleep is DISABLED by default, and i havent touched this setting, any advice ? thanks

Dear Mrshrir,
Thank you for choosing ASRock.
Regarding your case, please try to clear CMOS to load BIOS default.
If still does not work, please get into BIOS setting page and check if pressing shutdown button can shut down the system and fans.
Thank you!
Yours truly,
ASRock TSD

this occured after disconnected pc parts for a while, and moving pc parts from one case to another, bios somehow DID reset itself. and it didnt matter when i pressed the power button or if i shut down from windows.

So if you shut down the computer from Windows the fans still run ? That should not happen no matter what your BIOS settings are. Could you have shorted or static discharged something when moving the board from old case to the new one ?

i used splitters to run 9 fans off a 6 fan commander pro fan controller, gave up with the whole fans off mobo headers. it remains a mystery
