Which fan exactly? One plugged into the MB? Its not strictly necessary, you could connect it to a molex cable with one of those adapters.

The rear fan hat is screwed to the back of the case not the cpu fan.

Maybe this will help
Are you sure its not the CPU fan (mounted at the back of the case at the end of a duct from the cpu)?

Does the new fan have two wires, and the old one three? If so, you can't get a speed signal from the fan, so you will get that error message.
