5 wire fan wiring? anyone know?

[Fitseries3]

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)

 

[Fitseries3]

they have red, 2 black, yellow, and blue.

 

[Fitseries3]

looks to use a pcie connector.

 

[DaMulta]

I'd say

yellow power

2 blacks ground

blue read out

 

[Fitseries3]

why are the blacks always on the ground?

 

[2lowSniper]

I'd say

yellow power

2 blacks ground

blue read out

Uhmm 2 blacks? lol aren't you missing a color there dude? heh

Just saw Fits post but you did miss red. there's your power

 

[Fitseries3]

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

 

[2lowSniper]

That could very well be dude.

Didn't see the red.

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.

 

[Fitseries3]

no info at all on it. been searching for a week now.

 

[DaMulta]

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....

theres info sheets on some delta fans here, not sure if they have that connector (it may be dell specific), but worth a look if you know the model no

 

[Fitseries3]

all it says is red = + and black = -.

says nothing about the other wires.

 

[DaMulta]

maybe yellow is a remote antenna wire like in a car stereo...

 

[Fitseries3]

and blue hooks to a smurfs ass right?

 

[2lowSniper]

AHAHAHAHAHAHA Yellow is hooked to Smurfet it's for her hair dryer dude bahahaha

 

[Binge]

and blue hooks to a smurfs ass right?

+1 Smurfodomy

 

[DaMulta]

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.

 

[Fitseries3]

joking aside.... once we figure out the wiring delema all i need is a harness made and sleeved for 8 pcie connectors...

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?

 

[Fitseries3]

so plug and play may not work?

im ordering these in the morning so i need to know asap.

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]

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
