[SOLVED] Converting a 6 pin Delta to a 4 pin?

[crubleigh]

I pulled some Delta PFC1212DE's out of a Dell server and would like to put them in my new build however the dell bs connection has 6 pins. I need to splice this into a 4 pin but I don't know what 4 pins. I found the data sheet for the 4 pin version of the same fan and it seems the yellow is PWM and Blue is F00 (tach maybe?) red and black are positive and negative, however there are 2 red and 2 black wires. I definitely need the PWM control on these since they sound like jet engines. If anyone has any ideas that would be very helpful. Here's some pictures: https://www.delta-fan.com/Download/Spec/PFC1212DE-F00.pdf

I just want to say, you're NOT going to like the noise profile that the delta fans produce for home use. I'd suggest looking elsewhere.

It can't be much worse than what I have now. Also hence the speed control.

Initial google searches haven't produced anything. I'll continue digging.

My gut reaction would be to twist the two blacks and two reds together to achieve your 4-pin layout.
