4 pin RGB Pump to 3 pin RGB controller

[namarino]

Hi everyone. Wasn't sure where exactly to put this so sorry if it's in the wrong place. I have a res with 4 pin rgb cable and an rgb controller with only 3 pin rgb headers on it. Obviously the res's rgb didn't work when I plugged it in to the controller. Is there anything I can do to make this work? I didn't know anything about rgb when I planned this. Thanks for the help!

You want something like this.

So I plug the pump header into this and then into the 3 pin controller?

sorry no, i got it mixed up this takes a 4 pin in. I can't find anything that works the other way. What is your motherboard's make/model? you may already have a way to power it. also what's the make/model or the rgb controller?

Unfortunately my mobo is a z97 board and doesn't have any rgb headers. I bought the EK loop connect controller.

3-Pin is DRGB, it's addressable with 5V current (pinout is usually +5V / D / GND). 4-Pin isn't digitally addressable, it sports 12V (pinout is usually +12V / G-GND / R-GND / B-GND). Both systems are not compatible. You can try and find an adaptor that puts out an analog 4-pin RGB signal and has its own power connector. That's your only chance. Something like this should work: https://www.amazon.com/DEEPCOOL-Convertor-Transfer-Motherboard-Products/dp/B07QPYSC82

@bowrilla I linked the same adapter, its listing/product name is very poorly worded. It actually takes a 4 pin analogue signal from the MB and turns it into a 3 pin digital one. OP wants to go the other way, 3 pin > 4 pin.

 

@namarino Sorry for the late reply. I had another look around, i cant find a suitable converter, its just not something many people would need. The only other option is another controller, if you just want it to light up a cheap sata powered contoller should work. If you want software control it will have to be a more expensive usb connected controller like your EK one.

 

cheap option. I know it comes with a strip you prob don't need/want but for $5 shipped it doesn't really matter.

Oh, didn't follow your link to be honest. Deepcool or amazon messed up than because it clearly is misleading in that case.

 

I'm surprised there isn't a hub for this because it's not that hard to acchieve. Would be a nice microcontroler electronics project.
