ill check in bios but i doubt the answer is there. I think ive already checked there actually. I let the fans run to see how long they would stay on. They stayed for over 1 hour so I doubt its a timer.
i know its not the PS because I tried it with 2 diff models but those fans are still kickin after shutdown.
Just to double check what should I be looking for in BIOS incase I missed something?
