Help with RGB Fans

[friendlyJai]

I am building a new PC which comes with RGB fans that I am not familiar with.

Here are the components of the build

Case : Cougar MX660 Mesh case with preinstalled RGB fans and controller
Motherboard : Gigabyte B550 Aorus Elite V2
CPU : AMD Ryzen 7 5800X Processor
GPU : Zotac Geforce RTX 3070 Ti
PSU : Msi A850GF
Cooler : BeQuiet! Dark Rock Pro 4
Storage : Crucial P5 Plus 500 GB PCIe M.2

The Fans have the standard 3 pin cable for connecting to the SYS_FAN on the motherboard but also a cable to go to the controller. I connected all three to the controller and there is a cable from that that I have connected to the LED Strip header on the MB and another to the Sata for power. I would have though this would provide the power for both lighting them up and to spin the fans. When I fired up the PC, the lights go on but the fans don't spin. Was I therefore supposed to connect the other cables too?

The first picture show a 4 pin PWM fan connector that should connect directly to your motherboard. The second picture is a board that looks to be a lighting distribution board only, so will not power the spinning of the fan, only the lighting.

Edit: to add, the three pins connected to the circuit board are for ARGB lighting only

Thankyou. I will purchase a splitter for the 4 pin PWM Connector so I can get three fans into one header since I only have three headers in total on my MB.

I was actually thinking of replacing the other three standard fans with the same or similar ones to the front ones that are connected to the circuit board. I take it I can use the three slots on the side of the board?

I did have a search for RGB fans but they looked like they used different types of connections and controllers. Could you suggest a similar fan I could buy to replace them with? I thought it best to buy the exact same ones as the ones that came with the case but they don't tell you which ones they are.
