Corsair 4000X RGB case fans - only one seems to work as an actual fan

I bought the 4000X RGB and installed everything, seems to work fine for the most part. The three fans on the front panel light up fine with RGB, but only the top fan is spinning.

All the cables were labeled, so I plugged the one fan into the MOBO fan channel, which I guess I assumed was daisy-chained with the others like modular power, so that one being powered would power all three, but no, only the top fan spins. Which is weird, because all three are lit up fine.

Are there two additional fan power cables that I'm missing somewhere? I'd prefer not to take it apart again but I can if needbe, but I didn't see a single other plug that was ready to plug in, unless it's hiding somewhere.

MOBO is the B560-A by Asus ROG, if that matters. Thanks.

There is no daisy-chain between the fans. Each of those fans has 2 connectors - 1 for RGB and 1 for PWM (Fan motor). BOTH need to be connected (to different places).

Well, if you only have 1 PWM connector on the motherboard then yes, there are 2 additional connectors that you'll need to find. You could use a 1:3 splitter to run them from the same motherboard port, if you like.

No daisy chained fan cables in the Corsair system. Each fan has separate PWM and RGB wires and each needs a controller. You have 2 more PWM wires hanging about somewhere.

Thanks for the info, it turns out the two cables were buried in the backside of the fan itself, so I had to remove the panel and plug them into the channel fans and now everything is well.

Thanks!
