I know this is crap, but I tried to plug in one 4 pin to another and it shut down my PC, any advice on how to refit them to the right slots? its an Ibuypower
Sorry I meant just the rgb lights of the fan, the fans still run, on the back side there’s like 100 plugs and a few of them are 4 pins I can send a pic laterNever plug something while the system is running. There is a good possibility that the header is dead.
Try booting without case fan being plugged. Does the system post?
