So I have a Red LED Rosewill Cullinan MX case, I also have an Asus Crosshair motherboard. The manual for the case says to just plug in the molex into the PSU and the 3pin connectors to the fan control unit on the chassis. I did that the fans were running the other day just fine, and now they do not. Can someone help me with what I might be doing wrong?
The front panel works, minus the headphone Jack's? So I'm wondering if that side doesn't work which includes the fan control switch but I don't know why that wouldn't work when everything else works.
