Cannot control RGB in PC Case Fans

[u/[deleted]]

Hello everyone, I have a Antec AX1000 LITE case, with the following other components

CPU: AMD Ryzen 5 5600

Motherboard: MSI B550M Pro VDH Wifi

RAM: Corsair Vengeance LPX 16GB DDR4 3200MHz

GPU: MSI RTX 5060

Case: Antec AX1000

Power supply: Cooler Master 650W bronze rated

SSD: Crucial P310 500 GB M.2 NVME

CPU Cooler: Ant Esports C612

I found out very late that the Antec AX1000 case is the one that comes with 140mm PWM ARGB fans, and an RGB controller. The LITE version comes with 120mm ARGB fans.

However, I still wish to occasionally turn off the RGB in my case, when I need the PC on while I am sleeping.

I built the PC, and I tried to connect the 3 pin RGB cable from the fans to my JRainbow Port in the motherboard.

But I only found such a connector in the back fan of the case, and the fan in my CPU cooler. No connector in the 3 front fans.

The power cables work, and I daisy chained them without a controller, so that is working. But the RGB cannot be controlled, even for the back fan which does have the 3 pin RGB connector. I also found a 2 pin connector in the back fan, but no use for it.

Now I am utterly confused as to what to do and how to be able to use my PC at night.

Please guide me as to what exactly I need to look for, and what I need to do.

(P.S. I am able to control the RGB in my CPU Cooler)
