The fan will keep going until cooled down. If it keeps running after several minutes, the temperature gauge may be faulty - it think sit's hotter than it is?
No electronic equipment like consoles or computers or phone chargers or newer TV's are really "off" if they are still plugged in - especially if they have sleep modes. They draw power constantly.
I saw a bunch of products at CES this winter that are trying to change that - powerstrips that you can use that will block that slow passive energy drain and save a ton of power.
