Had an issue recently where my #Corsair #iCue #Link #LX140 & #LX120-R fans got locked on max speed. It was after a temp warning shutdown.
Restarting, reinstalling iCue, disconnecting and reconnecting cables; did nothing.
In the end turning off the PC and clearing CMOS fixed it.
Fans are working again.
Maybe this info will prove useful for someone else one day. Maybe no one who needs it ever finds it. Maybe no one ever has my exact issue.
