Small Fan on TAZ 5

I have a TAZ 5, and i was wondering if the small fan (or at least the smallest fan) it is supposed to be on all the time? and i dont mean on while im printing, but on all the time, i notice that im not printing and nozzle temperature is set to 0 and the fan is still running, is there a way to turn it off when not using the printer or it has to be on all the time?

thank you, and sorry if the question was ask before, but could not find it.


When the printer is powered on it is running. No control over that, except to turn off the printer when not in use.

oh ok! got it
