I'm using the motherboard from a Dell Inspiron 3847 for this build but I can't figure out the front IO and I can't find instructions for this motherboard anywhere. In the original case the front panel IO is handled by a single cable. Is what I'm trying to do hopeless? Surely there's a way to connect this to my new case.
Awesome! Yeah dell makes it complicated, but there is method behind their madness.
Their cables all check if they are connected to what they are supposed to be connected to, so that mass assembly troubleshooting is automatic.
So the work around on the adapter board and manual wire setups is to jump one pin over to another to fake that the cable is connected to the item at the other end.
Why they chose to mess with fan wires is beyond me though...that's just cruel
