These fans have two cables attached.

One is the 4-pin cable for power, and this was connected with a splitter. Both fans operate normally.

Another connector is a 4 pin connector with a blocked 3rd pin. These are what Fractal calls "chained connectors."

https://www.fractal-design.com/home/product/casefans/prisma-series/prisma-al-14-/pwm (scroll down a bit, where components are listed).

I assumed these were cross-connected to chain the two fans. What I mean is Fan 1 Male to Fan 2 Female and vice-versa.

The leds don't light up on either fan. Is there something I am doing wrong?
