Help me with QSC K10 speaker fan not working

How do you know fan is not working?
QSC claims it´s a "very low noise fan"

Also: fans are not always ON, many are temperature controlled and if amp is cold, as in used at home or very low volume, it might never turn on.

Is it new?
Does warranty still hold?
If so, rather than asking at a Forum, ask seller or straight call QSC

In any case, you know the drill:"no User serviceable parts inside"
