Question ARGB fans with no ARGB header?

Hey everyone, newbie to this forum. After some help. Just finished a build for a friend and the 3x ARGB fans included with the case dont light up with the included fan hub, nor does the motherboard have ARGB/RGB headers. The case is a CiT Cense case, and the mobo is an AsRock B450M HDV. Not sure on brand of the fan hub, but the SATA powers the fans through it, but doesn’t light them.

Not sure how to insert photos on here, but the hub has a connector for the FP led switch, SATA power cable, and a PWM/ARGB connector with 3 connectors on the end (ARGB 3pin, 4pin connector, and a VDG connector).

Welcome to the forums, newcomer!

Host your images on a site like Imgur or their ilk and then pass them onto this thread for us to see.

You will need an ARGB controller akin to this;
but I think you should've gone with a motherboard that had an ARGB header on it to forgo the extra expense.

Can't find details of that case and its Hub. What I can deduce from its description is that the HUB is really two Hub devices in one board - one part for fan MOTORS and another for LIGHTS. In each case it has OPTIONS - either control manually using buttons on the case, or have the board turn over control to s signal fed from a mobo header. For those purposes it has a three-headed cable to reach mobo headers.

For the fan MOTORS the cable includes a 4-hole female connector that goes to a mobo SYS_FAN or CHA_FAN header, and this will be used to control the speed of the CASE ventilation fans. Do NOT connect the CPU cooler system to this hub - use the mobo's CPU_FAN header for that cooling system. That mobo case fan fan header must be set to use the newer PWM Mode, rather than the older Voltage Control Mode (aka DC Mode).

For the lights on the fan frames, either of the other two connectors on that three-headed cable can be connected to a mobo ARGB header, but as you say there is none. The default in that case is that there should also be a cable from the board to a case top right button marked LED. You use that button to step though a selection of effects in the fan lights.

Each fan shpuld have TWO cables from it, ONE of these will end in a 4-hole female connector to plug into FAN MOTOR port on the board. the other will have a 3-hole connector to plug into a board LIGHTING port. I have assumed (not always a good idea!) that the fans supplied have "normal" separate cables for these two funsctions. There are SOME fans that use only one cable with many connection holes, and these match non-standard ports on the Hub.
