It sounds like your new fan doesn't have a timer.
Please look again at wiring colours and list them here, a picture would be better especially of old and new fans terminals.
Adding pics is easy just click copy on the pic and paste in here.
Are you sure the old fan actually had an earth terminal?
It may have been a switched live terminal, indicating a timer fan.

Maybe some numpty has used the earth conductor for something else. Did you make a note of which wires went where on the old fan?

sounds like the 2 wires you thought were L and N maybe actually permanent Live and Switchlive, when you turn the light off the fan motor is getting a Neutral return via the lamp.

That sounds like a distinct possibility.
I can't think of any other reason but I want to know the cabling before I offer advice.
