Unplug the switch at the radiator.  If the fan stops, bad switch.

If that's not it, normally either the fan relay on the fuse/relay
panel or if you have A/C another control relay

Yes, pulling S1 should stop the bleeding without diagnosing the
issue.  Since the fan motor is highly inductive, I'd expect a
considerable arc when you unplug the fuse, so not recommended to do
it a lot with the fan running.
