Help with RGB Fans

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?

Yes 100% the cables you have connected are all rgb cables, the other cables have to connect to fan outputs on the motherboard.

Thankyou. I just clicked that the circuit board just allowed more of the RGB cables from one RGB header on the motherboard. So the Sata power just gives them more power.

I was actually thinking of replacing the other three plain fans with the same or similar RGB ones that are at the front. I could use the other three slots on the other side. I have ordered two splitters for the 4 Pin header allowing three fans into one.

Can you suggest similar fans that might be compatible with them. I did have a look but a lot of them come with their own controller and different connection types so is a bit confusing.

Thanks again

This wee fan hub is cheap and I've found they are pretty good not had one fail yet, might be worth getting one. Runs 4 fans from one motherboard header.
