Can the laptop's cooler rustle even though the laptop is off?

Is it really disconnected from the electricity? If not, it may only be on standby

It is really disconnected from the electricity.

Shouldn't actually make any noise because there's no power to operate the fan. However, power could still come from the battery. How long after the fan is turned off?

It can't actually rustle unless it is in standby.

Nope 😅😂 Cringe!

Even if the battery is empty or removed? Some of my Toughbook still cools down, but that is a completely different category of devices. This shouldn't be the case with a normal laptop.
