I ordered 30 of these... but they have 4 black wires. The connector has no markings... I have no data sheet. I have no clue which goes to the S5 Red White Black Blue.

Data sheet for the fan can be found
here. Look on page 5 for wiring info:
Pin 1: Positive [12V]
Pin 2: PWM control IN
Pin 3: RPM reporting OUT
Pin 4: Negative
That's going to need rewiring to fit on S5s as normal 4 pin fan headers are:
Pin 1: Negative
Pin 2: Positive [12V]
Pin 3: RPM reporting OUT
Pin 4: PWM control IN
Might be worth sending back.
