    im getting some fans that have a 5wire connector on them.

    does anyone know how to wire them up?

    they are 24v fans for a dell server and im wiring them to a meanwell 12v psu.(they will work. already tested)

    as big as the fan is and for what it was designed for im assuming its like this....


    yellow - 24v power
    red - 12v power
    blue - RPMs
    black - 24v ground
    black - 12v ground

    Didn't see the red.:eek:

    Yea that would be my guess too

    I bet your could tie the red yellow together, along with the black.

    Then do what you want with the blue....toss it or hook it up one or the other.

    I would double check with the manufacturer (web site?) once you know the model number. They probably have a pin out listed somewhere.

    Well it is DC

    not

    AC


    Little harder to fry......so you could play around


    Hooking it up backwords should just make it spin backwards....

    says nothing about the other wires.

    you never know....it could very well be up a smurfs ass.



    I bet there is controller that can switch between different voltages for different speeds. Just hook up red and black and see what she does.

    As far as google can tell it maybe a Unipolar 4 Phase Stepper Motor in the past used in 5 1/4" floppy disk drives. Reading up you may need a controller to control the output to the different phases. How did you get them working in the first place?

    I reckon connect the yellow and red together and the two blacks together and apply only 12V for the moment. To make sure, I would say you should get the same resistance reading between yellow-black and red-black, the blue I would also assume is RPM, between blue and black should be different, the odd one out. Got to say though, you are definately a hardware junkie!
    Fitseries3 says thanks.

    yeah... if you do the math...

    8 x 237cfm = 1896cfm

    but then you think they can run from 3v(i tested) to 32v... i bet thats over 2400cfm. i gotta bolt this thing down or it will take off.

    Hook the black upto the ground and play around with the red wire, should be fine. they ain;t that easy to blow up

    How about getting one of these fits? http://www.streetrodcatalog.com/manufacturers/spal/fans.shtml

    From reading around - jst been googling - It seems the extra wires are just for speed sensors and control - not an issue if your going to be running them at full. just use the standard wires and ignore the extras
