Q Fan is not a separate fan, it is a program which adjusts the speed of the fan depending on the temperature of the chip. Before you enabled Q Fan your fan was probably running at max speed all the time (which was the noise you could hear). With Q Fan enabled the fan will now adjust it's speed depending on the temperature. So if the system gets hot you will probably here the fan kick in again until it cooled off. You should open the computer case and have a look at the fans to make sure they are spinning freely and not choked with dust.
The power of accurate observation is commonly called cynicism by those who haven't got it.
