honestly im not sure i just purchased a spider farmer inline fan with a EC motor and it has no whine at all no matter if its dialed down or at full speed its silent!!! the only thing i hear is the air moving. but maybe your's just does that naturally i have no idea. i hope someone with a Q max fan can chime in.
also if you dont mind me asking how much did you pay for it?

Yeah I expected silence tbh, it is used tho so maybe some fuckery going on. Fan was £180 which is a great price for this its a beast, but uh not if its not 100 percent. The controller was £35 I think. What price was yours what size is it?

Venting and routing can cause excessive noise

I have 2 ac infinity inline fans. 1 for intake, 1 exhaust. Both quiet as hell.
No it's definitely the fan, it's not even connected to any ducting yet.
I thought maybe the fan blade was rubbing lightly on something but the noise stops when I shut the speed controller off but the fan is still spinning fast, so it's something to do with the electricity.

My ac infinity fans are EC motor and they whine at certain speeds, im gonna test bigger carbon filter cause i was using smaller one which had capacity to level 5/10. As i tried restricting airflow by bending duct attached only whine also showed. Maybe thats your case ? I use EU converter for them. So we are in this together 
Edit OK i saw that you have whine without anything attached. It can be unblanaced blades or something. If u are gonna use it still, try to isolate duct from the fan - something rubbery attached to duct etc to dampen vibrations (whining can be low frequency)

Mine has something to do with the electricity, when I turn the electricity on it whines, if its still spinning fast and I've turned the electricity off there's no whine. It also whines with no speed controller so it's not the speed controller either, it's got to be the motor.My ac infinity fans are EC motor and they whine at certain speeds, im gonna test bigger carbon filter cause i was using smaller one which had capacity to level 5/10.

Good luck with your problem.
