Chassis Fan 1 - The problem I am having is my side panel chassis fan is not working. The four prong cord from the chassis is plugged into the power cord, it is powering (2) fans. The rear fan is connected to the MOBO (chassis2 header). There are no other cords coming from the chassis for the side panel fan, but the (2) fans running off the power supply have a double sided cord from the chassis (male/female 4 prong). The other thing that is strange is my power button is not lighting up.
