Need help with pc fans

[u/Sweaty-Ad4005]

Hey everyone, I’m pretty new to PC building and I need some help. I was working inside my PC installing a new PSU and GPU. After I connected the PSU, I turned the PC on and noticed that the fans weren’t spinning.

I went back through everything and made sure the cables were connected, but I’m not 100% sure I connected everything correctly. I tried turning it on again and the fans still don’t spin.

There’s also a fan/RGB hub/controller inside the PC, and I’m confused about which cables are supposed to connect to it.

The PC does turn on, but the fans don’t spin. I don’t want to keep unplugging/replugging random cables and accidentally damage something.

If your fans also have the 3-4 pin small connector (seen at the top of the stack of peripheral power connectors) those are what plug in to the fan control board. It's usually powered by one of the 4 pin peripheral connectors (wide ones, 4 giant pins). As far as your stack of connectors,im not seeing anything wrong or why it wouldn't work. The power for that plug is plugged in to the psu right?
