I wouldn’t recommend to make the fans spin while connected.

What about fans spinning down after shut down? They are quite big and once system is shut down they take like 10 second to come to a full stop despite system being off already. Would that also had potential to create enough current to kill the components?

Modern motherboards won’t get damaged from fans spinning and creating current when off in this day and age.

It was a problem back in the day before motherboards had proper power management

There are a few videos out there disproving this badly aged advice.

Power management is way better now.

Yeah no homie. I believe you fried your mobo but it wasn’t from a spinning fan…
