I think it should. but remember I've had motor work done and it really generates some heat
but if your not riding it hard it might take a while to come on
sorry about the crash. I know how you feel. crashed mine in march

 

Mine comes on a lot too. If you don't have coolant boiling out through the overflow tube and you don't need to replace coolant often, then I would think the fan is doing it's job and that is helping the quad cool down. I know when I first bought mine, I worried about it[img]i/expressions/face-icon-small-blush.gif[/img] but, so far, I haven't had to add any coolant[img]i/expressions/face-icon-small-smile.gif[/img] other than, when I replaced it.

Now that I have 2 Z400's[img]i/expressions/face-icon-small-smile.gif[/img] I'll pay more attention to the fans and compare how often both come on.
