Default 400W(?) fan in oil radiator

I was staying at a friend's house and noticed that his oil radiator (similar to the one pictured below) has a built-in fan.
The info tag claimed that the radiator's total power is 2400W: heating is 2000W and 400W for the fan. Can that be right? Can a small fan like that really need 400W? The airflow seemed comparable to a 80mm computer fan which uses only a few watts, so why does this need so much?

EDIT: On second thought maybe there is a 400W heating element in the fan? But that wasn't included in the radiator's heating power on the tag
