SPAL fan setup question

Assuming you are running the factory DME (?), does the DME care that its PWM fan speed control signal that used to connect to the OEM fan isn't connected to anything?

I'd assume "no" but someone is telling me that the DME will put the car into limp mode if it sees the fan control disconnected (perhaps not immediately, but still before actual overheating)? I'm inclined to believe he's conflating that with the cars just overheating because the fan was unplugged, but I could be wrong. If that's actually true, I'm wondering if a little resistor might have solved that problem?

Thanks!
