post #1 of 7
Thread Starter 
need help wiring one of these fans onto a molex, 3 wires blue red and black and a funky connector (i think its some kind of server connector) can i just put the black to black and red to red and leave the blue (assuming its speed sensor) alone?

Yeah should be able to just put red to red and black to black and let it run at full speed.

Probably a Dell fan connector.

Where did you buy the fan? They should have a datasheet pdf that will let you figure out what wire goes where.

You could look at where the wire is attached to the pcb on the fan.

Unfortunately on the Deltas that I have you can't get at the PCB.

I have a pair of 2-wire Deltas that came with a plug which would connect up with pins, as long as I clipped off that thing on the top of the plug.

I wouldn't assume the colors mean anything.

Does it look like this:

no, it reminds me of a connector that would come on a gpu heatsink, shorter and wider than normal 3 pin connectors
