    fan issues

    I ordered a turbo fan off of wish and cant get it to work. The fan that cools the extruder is always running so i ulpugged it and pluged in the new fan and nothing happens. I dont know a whole lot about electronics but does it have to do with the volts and amps of the fan?
    p.s the new fan is 24volts and .12 amps
    i also have another aftermarket fan that is 12volts and .09 amps and that one dosnt work either. The one on the printer is 12volts but dosnt say how many amps

    Hmm. Are the fans you brought 2 or 3 wires ?

    Computer fans usually have 3 wires, positive, negative and speed control.
    I suspect if the thrid wire is not connected the fan probably won't work.
    The two fans (24v) I use on my cooling ducts are just two wire.

    I've only seen two wire fans used.
