Help with a fan solution

[Tommokelly]

I've recently bought a Gigabyte b450m ds3h motherboard and a Corsair Carbide Series Spec-Delta RGB case.

 

I'm trying to figure out how I can power and control the 3 RGB fans at the front of the case, as I don't believe the board has a 12v RGB header.

 

There is an LED-CPU header on the mobo but I'm not sure if that's what I need to be going into? If I was to go into this, do I lose the ability to control the speed/colour via software and it has to be done through BIOS?

 

Any help would be appreciated.

 

Cheers.

the fans of your case using a 12V 4Pin RGB header for light and a 3 Pin fan header  for voltage speed control.

your motherboard has 1x 12V RGB header. so you can connect your fans directly to your  motherboard to control the lights.

for fan control: your motherboard only has 2x fan header (SYS_FAN & CPU_FAN) so you need a splitter to connect all your fans (3Pin connector).

So the LED_CPU header on the motherboard is a functioning 12v RGB header that will allow me to control the RGB lights on the 3 fans?

 

The part I'm getting confused with is the control bit. The case did come with an RGB splitter, as can be see on the PDF manual attached (page 9). Where does this need to plug into? The SYS_FAN header?

 

Is this everything I need to be able to power and control these fans?

Your fans have to different connectors. One for RGB and one for the fan itself (and speed control).

Fans are power with the 3Pin connector.

If I was to buy a splitter (https://www.ebay.co.uk/itm/1-To-5-4-Pin-PWM-CPU-Fan-HUB-Cooling-Splitter-Adapter-Braided-Power-Cable-40cmVQ/163675027159) like this, would I be able to power the 3 front fans, as well as the back fan? I don't want to overload my mobo obviously.

you could buy one of those splitters and connect your 4 fans to it and the splitter to SYS_FAN. your CPU cooling fan to CPU_FAN. RGB connector with splitter to LED_CPU.

your mobo can handle even more.
