Convert 4-pin RGB to 3-pin RGB setup
Convert 4-pin RGB to 3-pin RGB setup
Hi guys, this is kind of an abstract question. I have an Asus Prime Z390-a board with a 9900KF. I'm not interested in changing my board/cpu. I did however switch to a bequiet! light wings 360mm aio, and It has a 3 pin RGB connector. Those who are familiar with this board know that it doesn't have a 3 pin RGB connector, anywhere. It only have 4 pin connectors, which obviously won't work with this cooler. I did some research and have been completely unable to find ANY solutions, other than to get a different board, which is off the table. So on that topic, how could I go about getting RGB to my pump/water block and the fan hub? I'm not necessarily opposed to adding a converter, like some people have said will/could work. If you guys know anything, let me know. I'll be busy the rest of the day as I have a final. Thanks in advance

Connect the RGB to the appropriate port on the controller, and ensure compatibility. Be cautious—standard adapters often fail. A 5V signal on a 12V system is acceptable for RGB, but it may not function properly. Using 12V with a 5V RGB setup can damage the system and disrupt other components.

Choose between a hub or a hands-on approach if you already have a buck converter. You can reduce the voltage from 12 to 5 volts. I found some 3D printed 2-pin 25x25 fans that improve airflow between my GPU and motherboard. They work on 12V but can be quite loud at high speeds. I used a buck converter to lower their voltage and speed. I purchased 10 buck converters for $15 on AliExpress.
Alternatively, ARGB format uses three pins: a +5v input, a data pin, and a ground pin. The controller or motherboard selects which LED displays each color, while the data is translated into voltages for the LEDs. This setup allows you to control RGB fans using ARGB via a microcontroller, which interprets the digital signals and sends commands to the fans.
If you want to manage RGB LEDs from Windows, there are controllers available with USB2 connectors. These let you adjust colors through an app, sending commands that the controller translates into voltage signals for the fans or pumps. This approach offers greater control and flexibility, especially if you prefer using RGB controllers that connect via USB and offer intuitive apps.
Feel free to ask if you need more details!

Each connector includes one input for +12v to control the RGB device, and this voltage feeds all the LEDs in the fan or similar RGB equipment. The remaining three pins serve as ground connections—one for blue, one for green, and one for red. When selecting a color, the motherboard determines the required intensity of each LED and adjusts the voltage accordingly. Using MOSFETs or transistors on the ground side, it regulates the color output. However, all devices display the same color because there’s no processing on the device side; instead, three LEDs switch on or off based on the voltage they receive.

07-16-2018, 09:49 AM #8Yes, my previous fans were Corsair and used the USB header for color control. I hadn’t considered this method with the new fans until today in class. What’s a suitable option? Are there affordable controllers that work well?
What's accessible in your region differs from what you find there, and items that work locally tend to be pricier. Focus on nearby shops and ask them for the most affordable options that fit your needs. Remember, some brands have varying systems, so stay mindful of that. Opt for something compatible with your device.
